Biased but Better? Minimax Estimation of Average Treatment Effects | UW CSSS SEMINAR

SAV 409
Wednesday, Apr. 22, 2026, 12:30 – 1:30 p.m.

Abstract:

In the social and biomedical sciences, researchers often seek unbiased estimators of causal effects. Yet unbiased estimators are often inadmissible, in the sense that a biased alternative will always have lower expected error. This raises a natural practical question: how much is gained by using biased estimators instead? In this talk, I present an algorithm for computing minimax estimators of average-treatment effects from experimental data and compare their performance with that of the standard difference-in-means estimator.

Conor Mayo-Wilson is an associate professor in the philosophy department at the University of Washington and an affiliate faculty member in the Center for Statistics in the Social Sciences. His philosophical interests are rather broad, spanning much of epistemology (esp. formal and social), philosophy of science, decision theory, game theory, and philosophy of statistics.

CSSS Seminar - How Militarization Impacts the Climate Crisis: A Global Perspective

Wednesday, Apr. 22, 2026, 12:30 – 1:30 p.m.

Andrew Jorgenson, Professor of Sociology, University of British Columbia
Wednesday, April 22nd, 2026 - 12:30 pm

Abstract:
In this talk I will provide a broad overview of my collaborative research concerning the ways in which militarization, as a form of coercive power, contributes to anthropogenic carbon emissions for nations throughout the world. First, I will summarize research on the short-run and long-run effects of militarization on national carbon emissions. Second, I will describe research that focuses on how militarization shapes the effect of economic growth on nations’ carbon emissions. Third, I will summarize research on militarization facilitating and supporting transnational capital in Global North nations outsourcing their carbon pollution to Global South nations. This body of empirical work serves as the foundation for a book in progress.

Andrew Jorgenson is a Professor of Sociology and Founding Director of the Climate & Society Lab at the University of British Columbia, and a Senior Research Fellow in the Department of Theoretical Economics at Vilnius University. As an environmental sociologist trained in global political economy, he conducts macro-comparative research on the human dimensions of global and regional environmental change, with a focus on the societal causes and consequences of the climate crisis. Hi work appears in various disciplinary and interdisciplinary journals, including American Sociological Review, American Journal of Sociology, Social Forces, Social Problems, Nature Climate Change, Environmental Research Letters, Nature Communications, and Sustainability Science.

CSDE Seminar - Data Equity and Identity: A Qualitative Analysis of Public Feedback on Asian Racial Categories - Ninez Ponce

Friday, Apr. 24, 2026, 12:30 – 1:30 p.m.

Speaker: Ninez Ponce, Professor and Endowed Chair of Health Policy and Management & Director of UCLA Center for Health Policy Research, University of California Los Angeles

Abstract: Proposed changes to the federal racial and ethnic classification system in the United States offer a unique opportunity to understand how the general public thinks about Asian American identity and how Asian populations should be classified in federal data. The Improving Asian Classification Typologies (ImpACT) project analyzes public comments submitted in response to two Federal Register Notices: (1) the OMB's proposed revisions to Statistical Policy Directive 15, 2023, and (2) the U.S. Census Bureau's draft race and ethnicity coding guidelines, 2024.

Using a mixed deductive-inductive coding framework, six coders working in pairs analyzed comments to develop key themes. Overall, we found the boundaries of the Asian category are contested in the comments, particularly at the intersections with the Middle Eastern and North African, White, and Native Hawaiian and Pacific Islander categories. The geographic subgroups used to define Asian communities, including East Asian, Southeast Asian, and South Asian, are similarly disputed, particularly for communities with identities that traverse regional boundaries. We also found disagreement over whether Census' pre-defined regional categories should be retained or eliminated, with some commenters arguing that standardized groupings are essential for longitudinal research and reporting, while others contending that pre-defined categories introduce misclassification and can undermine community self-identification. Additional themes examine debates over terminology, data collection practices, and how classification decisions shape community visibility and health equity.

Marginalized Regression for Bounded Outcomes with Floor and Ceiling Effects | UW CSSS SEMINAR

SAV 409
Wednesday, Apr. 29, 2026, 12:30 – 1:30 p.m.

Abstract:

Outcomes studied in social science and health research frequently take the form of fractions or percentages with a defined lower and upper limit, such as the percentage of medication doses taken, the rate of condom-protected sex, and the number of substance use-related problems endorsed in a screening questionnaire. Such data commonly exhibit floor and ceiling effects due to many participants that never engage in the outcome (e.g., never take prescribed medication) or are consistently at the upper limit (e.g., take all prescribed doses). Prevailing statistical approaches used to analyze such data do not fully account for clusters of responses at the lower and upper limits, which risk invalid conclusions about the effectiveness of interventions and theoretical models. We introduce an accessible extension to zero-inflated regression, the marginalized zero- and N-inflated binomial (MZNIB) model, that can analyze fractions and percentage data on the entire range between zero and 100% with greater accuracy than prevailing approaches when assessing naturally bounded outcomes with floor and ceiling effects.

Dr. David Huh is the Director of the Methods Division at the UW Indigenous Wellness Research Institute and the Associate Director of the Methods Core at the UW Behavioral Research Center for HIV (BIRCH). A key emphasis of Dr. Huh’s research is increasing the accessibility of statistical approaches that can more powerfully and accurately assess behavioral health interventions and test theoretical models of health for both specific groups and broad populations.

China Studies Program - From Malthus to Musk: Searching for Population Equilibrium in East Asia

Thursday, Apr. 30, 2026, 3:30 – 5 p.m.

University of Washington

From Malthus’s warnings of overpopulation to Musk’s urge to boost fertility, the drastic turn of humanity’s relationship with population growth is one of the defining features of East Asian societies. Nowhere have demographic shifts been more seismic in their speed, scale, and scope than in East Asia over the past century. Populations in this region now simultaneously exhibit the world's longest life expectancies and its lowest fertility rates.

How did East Asian societies arrive at this point? Can they return to replacement-level fertility? Echoing the historical contrast between East Asian and Western European demographic regimes, we debate the existence of a distinct "East Asian model" of demographic transition. Adopting a regional and comparative perspective, we argue that intense family competition and proactive government intervention—both operating within the context of deep-seated cultural traditions—have defined the region's current demographic challenges.

We conclude, however, that policy interventions alone will likely prove insufficient without addressing the fundamental shifts in social values and the complex interplay of economic, cultural, and political factors driving this historic demographic transformation.

CACHE Webinar - Measuring Heat for Use in Population Research

Wednesday, May 6, 2026, 11 a.m. – 3:30 p.m.

PAA 2026 CACHE Workshop Registration: Measuring Heat for Use in Population Research
May 6, 1-5:30 PM CT

So many questions arise when trying to measure heat as a health exposure – let CACHE help!

Heat is one of the most frequently examined environmental influences on population health, and a wide variety of data sources exist to measure exposure. This workshop, sponsored by the Center on Aging, Health, and Environment (CACHE), provides an overview of heat measures and examples of two, including hands-on experience with code available via the CACHE website. Participants will generate temperature exposure measures from publicly available data, as well as wet bulb temperatures. The Universal Thermal Climate Index data will also be demonstrated and linked to population data.

The workshop’s first exercise uses data from two different sources: National Oceanic and Atmospheric Administration (NOAA) weather-stations and ERA5-Land Reanalysis from the European Union’s Copernicus Project. Both are publicly available. The workshop will review information on acquiring and cleaning daily temperature data for New York City, as an example. Key is that air temperature as well as wet bulb temperature exposure variables are generated, and at varying temporal resolution. On the CACHE website, the code is embedded in an R Markdown pdf file.

The second exercise demonstrates how to construct severe heat measures using the Universal Thermal Climate Index (UTCI, Copernicus ERA5-HEAT). It starts by showing data manipulation from raster (grid data) to a tabular dataset that obtains UTCI values for each municipality in Mexico as an example. Then, the data are mapped and analyzed as linked to population data. Finally, the number of days of severe heat (32°C UTCI and above) are generated. This code, also available on the CACHE website, is part of the demonstration CACHE project “Heat, Disability in older adults and Care” from El Colegio de Mexico.

Lead Instructors:
Dr. Frank Heiland, CUNY Institute for Demographic Research
Dr. Alex Mikulas, CACHE
Dr. Landy Sanchez, El Colegio de Mexico

Organizers:
Lori Hunter, University of Colorado Boulder, and Deborah Balk, CUNY Institute for Demographic Research

Using Multilevel Modeling to Investigate Agitation in Long-Term Care: Evidence from Older Chinese Residents | UW CSSS SEMINAR

SAV 409
Wednesday, May 6, 2026, 12:30 – 1:30 p.m.

Abstract:

Agitation is one of the most common and distressing behavioral symptoms among older adults living in long-term care facilities, particularly among residents with cognitive impairment. Despite its clinical importance, limited research has examined how individual and facility-level factors jointly contribute to agitation among older Chinese residents in institutional settings. In this seminar, Dr. Wang will introduce the application of multilevel modeling to investigate agitation in long-term care facilities serving older Chinese adults. The presentation will discuss conceptual considerations in studying behavioral symptoms across nested care environments, methodological decisions in multilevel analysis, and challenges encountered when working with facility-based data. The study underscores the need for person-centered strategies that consider residents’ psychosocial needs, family engagement, and organizational support within long-term care settings.

Kaipeng Wang joined the University of Washington School of Social Work as an Associate Professor in January 2026. His research examines health disparities and mental health among older adults and diverse populations, including ethnically minoritized and immigrant communities. Dr. Wang’s work addresses end-of-life care planning, cognitive health, and social determinants of health, aiming to improve health equity and quality of life for aging populations.

From Estimands to Robust Inference of Treatment Effects in Master Protocol Trials | UW CSSS SEMINAR

SAV 409
Wednesday, May 13, 2026, 12:30 – 1:30 p.m.

Abstract:

A platform trial is an innovative clinical trial design that uses a master protocol to evaluate multiple treatments, where patients are often assigned to different subsets of treatment arms based on individual characteristics, enrollment timing, and treatment availability. While offering increased flexibility, this constrained and non-uniform treatment assignment poses inferential challenges, with two fundamental ones being the precise definition of treatment effects and robust, efficient inference on these effects. Such challenges arise primarily because some commonly used analysis approaches may target estimands defined on populations inadvertently depending on randomization ratios or trial operation format, thereby undermining interpretability. This article, for the first time, presents a formal framework for constructing a clinically meaningful estimand with precise specification of the population of interest. Specifically, the proposed entire concurrently eligible (ECE) population not only preserves the integrity of randomized comparisons but also remains invariant to both the randomization ratio and trial operation format. Then, we develop weighting and post-stratification methods to estimate treatment effects under the same minimal assumptions used in traditional randomized trials. We also consider model-assisted covariate adjustment to fully unlock the efficiency potential of platform trials while maintaining robustness against model misspecification. For all proposed estimators, we derive asymptotic distributions and propose robust variance estimators and compare them in theory and through simulations. The SIMPLIFY trial, a master protocol assessing continuation versus discontinuation of two common therapies in cystic fibrosis, is utilized to further highlight the practical significance of this research. All analyses are conducted using the R package RobinCID.

Ting Ye is an Assistant Professor in Biostatistics at the University of Washington. Her research aims to accelerate human health advances through data-driven discovery, development, and delivery of clinical, medical, and scientific breakthroughs, spanning the design and analysis of complex innovative clinical trials, causal inference in biomedical big data, and quantitative medical research.

CSDE Seminar - Enduring Illegality: Time and the State of Waiting in Undocumented Middle Life - Angela Garcia

Friday, May 15, 2026, 12:30 – 1:30 p.m.

Speaker: Angela Garcia, Associate Professor of Crown Family School of Social Work, Policy and Practice, The University of Chicago

Abstract: How does the state govern immigrant lives not only through law, but through time? This book talk centers “illegality” as a temporal mechanism of U.S. migration governance: by withholding broad pathways to legal status, the state sustains prolonged legal uncertainty, blocked mobility, and restricted cross-border movement that structure the life course. Drawing on three waves of longitudinal interviews with long-settled undocumented Mexican immigrants in Chicago, the talk traces how those who migrated as young adults enter middle life in a condition of legal and temporal suspension that coincides with peak responsibility for others—raising children in the United States while supporting aging parents from afar. Examining the undocumented “sandwich generation,” the talk shows how family caregiving is reorganized through prolonged legal uncertainty: strain concentrates when children are young, responsibilities shift onto adolescents as they age, and care for parents abroad becomes coordinated long-distance support marked by the emotional costs of absence, even as immigrants’ own later-life security remains uncertain. By centering time as a tool of migration governance, the talk offers a structural account of how immigration policy produces inequality that outlasts any single reform or administration, embedding waiting, deferral, and constrained mobility across the arc of adulthood.

Bio: Angela S. García is Associate Professor at the University of Chicago’s Crown Family School of Social Work, Policy, and Practice, with affiliations in Sociology and Comparative Human Development. Her research examines international immigration, law, and membership, focusing on migration governance and the shaping of immigrants’ long-term life chances. Her first book, Legal Passing: Navigating Undocumented Life and Local Immigration Law (University of California Press 2019), compares how restrictive and accommodating local immigration contexts reorganize undocumented life and drive strategies of “passing” within uneven legal landscapes. Her second book, Enduring Illegality: Time and the State of Waiting in Undocumented Middle Life (University of California Press 2026), shows how the state uses time as a mechanism of immigration control, with prolonged legal uncertainty shaping the life course into middle age through deferred futures and constrained caregiving, work, and health trajectories. García currently studies documentation and municipal ID programs across cities in the Americas and Europe, focusing on urban inclusion, administrative justice, and policy diffusion. She earned a PhD in Sociology and an MA in Latin American Studies from the University of California, San Diego, where she was affiliated with the Center for Comparative Immigration Studies and the Mexican Migration Field Research Program.

Almost Magic: The Promise and Pitfalls of AI-Assisted Coding | UW CSSS SEMINAR

SAV 409
Wednesday, May 20, 2026, 12:30 – 1:30 p.m.

Abstract:

Artificial intelligence tools are democratizing programming, making computational research accessible to researchers who have little or no formal programming background. This seminar offers a practical introduction to programming with AI assistance, beginning with a brief history of how AI—and AI coding tools in particular—came to be. We then discuss practical considerations for programming with AI: how to work effectively with AI assistants, how to frame problems clearly, and how to evaluate the code they produce. The foregoing skills are essential in addressing “technical debt” in AI-assisted programming, where generated code does not generalize easily to new features. The talk should provide insights into what AI-assisted programming can and cannot do, and a foundation for using AI tools responsibly.

Joseph L. Hellerstein received his PhD in Computer Science from the University of California at Los Angeles. He has thirty years of experience in research and software engineering at the IBM TJ Watson Research Center, Microsoft Corp. and Google. He is a Fellow of the IEEE for contributions to the control engineering of computer system performance, and has approximately 200 peer-reviewed publications. At the eScience Institute, his primary focus is on AI-assisted software engineering. His role in the Department of Bioengineering is teaching and research related to mechanistic models of biological systems.

CSDE Seminar - The Promises and Pitfalls of Social Scientific Instruction in U.S. Medical Schools - Lauren Olsen

Friday, May 22, 2026, 12:30 – 1:30 p.m.

Speaker: Lauren Olsen, Assistant Professor of College of Liberal Arts, Temple University

Abstract: Medical schools have increasingly incorporated the humanities and social sciences into their teaching, seeking to make future physicians more empathetic and more concerned with equity. In practice, however, these good intentions have not translated into critical consciousness. Humanities and social sciences education has often not only failed to deliver on its promise but even entrenched the inequalities that the medical profession set out to address.

Lauren D. Olsen examines how U.S. medical school faculty conceived, designed, and implemented their vision of education, tracing the failures of curricular reform. She argues that the way medical students encounter humanities and social sciences material in practice has served to reinforce the status quo by teaching them to individualize systemic problems. Students learn to avoid advocacy, critique, and attention to structural inequalities—while also gathering that it will be up to them to find coping strategies for problems from burnout to systemic racism. Olsen pinpoints the limitations of how clinical faculty understand the humanities and social sciences, arguing that in structuring and teaching courses, they assumed, reinforced, and glorified a white, elite model of the medical profession. Showing how deeply intertwined professional and social identities are in medical education, Curricular Injustice has significant implications for how occupations, organizations, and institutions shape understandings of inequality.

Bio: Lauren D. Olsen joined the Department of Sociology within the College of Liberal Arts at Temple University as a faculty member in 2019. Before starting as an Assistant Professor at Temple University, Dr. Olsen completed her PhD in Sociology at the University of California San Diego (UCSD), where she also received her Master’s degree in the same field. Prior to that, she received her Bachelor’s of Arts degree in Religion from Columbia University. As a sociologist of medicine, Dr. Olsen’s award-winning research has been published in flagship journals, like the Journal of Health and Social Behavior, Social Science and Medicine, and Social Problems and has a new book out with Columbia University Press (2024), entitled Curricular Injustice: How U.S. Medical Schools Reproduce Inequalities.

Dr. Olsen’s research lies at the intersection of the sociology of medicine, knowledge, education, culture, and social inequalities. Focusing on the case of U.S. medical education, she studies how educators, physicians, and policy makers apply knowledge to improve patient care and how the context in which these actors work impacts how they utilize knowledge. Dr. Olsen addresses questions about how these actors understand the sources of health and healthcare inequalities in the U.S. patient population, how they decide what kinds of knowledge are clinically relevant, and how they reproduce forms of inequality in their educational materials and interactional processes.

Building off of the research captured in her book, Curricular Injustice: How U.S. Medical Schools Reproduce Inequalities, Dr. Olsen is currently engaged in research on premedical students’ experiences and expectations along their career path with a team of Temple University undergraduates, medical students’ and educators’ conceptualizations and engagements with “service learning” with physicians and social scientists at Lewis Katz School of Medicine, medical students plans to serve primarily underserved populations with colleague Laura Orrico, and medical school leaders’ institutional statements about national and local policies affecting their patients, students, and communities with a Temple University undergraduate.

One Model, Many Methods: NIMBLE for Hierarchical Statistical Modeling in Social and Other Sciences | UW CSSS SEMINAR

SAV 409
Wednesday, May 27, 2026, 12:30 – 1:30 p.m.

Abstract:

People often need to customize statistical models for particular problems and then consider a variety of methods for estimation and inference. Customizations may include adding components across space, time, repeated sampling, networks, non-parametric relationships or distributions, or multiple data sources, among others. Methods may include MCMC with potentially many kinds of samplers, empirical Bayes or marginal maximum likelihood, Laplace approximation and its extension to adaptive Gauss-Hermite quadrature, integrated nested Laplace approximation and related methods, sequential Monte Carlo, and others. Some methods represent hybrids, such as Particle MCMC combining particle filtering and MCMC. I will give an overview of the NIMBLE framework (R package nimble) for such problems. NIMBLE combines a language for writing models (an extension of the BUGS/JAGS language) and an algorithm programming system from R, in which all built-in algorithms are written and users can write new algorithms. Models and algorithms are automatically generated into C++ and compiled, and they can use derivatives of arbitrary order. NIMBLE has been used in over 600 peer-reviewed publications across many fields, with a center of gravity in ecology and environmental science. I will illustrate NIMBLE with a 2-parameter logistic item-response theory model with nonparametric distribution of abilities for education and health data and with a multi-species occupancy model of bird species distributions in California. The first example shows use of Bayesian nonparametric distributions, while the second shows configuration of MCMC samplers such as Barker, slice, and HMC along with comparisons to Laplace and INLA-like nested approximations. Finally I will point to future developments for NIMBLE, including greater scalability, better workflows, and better use from other packages.

Perry de Valpine is a mathematical and statistical ecologist. His research interests include population dynamics, theoretical ecology, and computational methods for fitting biologically realistic models to data. He is a lead developer of NIMBLE (r-nimble.org), a flexible computational system for hierarchical statistical modeling. He has contributed to modeling and data analysis of many systems in environmental science, including bird communities, large carnivore populations, agricultural insect dynamics, forest change, soil microbiomes, plant chemical diversity, fisheries, and more. De Valpine is a Professor in the Department of Environmental Science, Policy, and Management and teaches courses on statistical and mathematical modeling methods in ecology and environmental science.

CSDE Seminar - Ice Geographies and Critical Demography - Jen Rose Smith

Friday, May 29, 2026, 12:30 – 1:30 p.m.

Speaker: Jen Rose Smith, Assistant Professor of Geography, University of Washington

Abstract: Ice animates the look and feel of climate change. It is melting faster than ever before, causing social upheaval among northern coastal communities and disrupting a more southern, temperate world as sea levels rise. Economic, academic, and activist stakeholders are increasingly focused on the unsettling potential of ice as they plan for a future shaped by rapid transformation. Yet, in Ice Geographies, Jen Rose Smith demonstrates that ice has always been at the center of making sense of the world. Ice as homeland is often at the heart of Arctic and sub-Arctic ontologies, cosmologies, and Native politics. Reflections on ice have also long been a constitutive element of Western political thought, but it often privileges a pristine or empty “nature” stripped of power relations. Smith centers ice to study race and indigeneity by investigating ice relations as sites and sources of analysis that are bound up with colonial and racial formations as well as ice geographies beyond those formations. Smith asks, How is ice a racialized geography and imaginary, and how does it also exceed those frameworks?

Bio: Jen Rose Smith (dAXunhyuu) is assistant professor of Geography and American Indian Studies at the University of Washington. She works at the intersection of critical Indigenous studies, cultural human geography, and environmental humanities. Her book Ice Geographies: The Colonial Politics of Race & Indigeneity in the Arctic was published with Duke University Press and she has also published in EPD: Society and Space, The Geographical Journal, and Transactions of the Institute of British Geographers. She serves on the advisory board for the Eyak Cultural Foundation, a non-profit that organizes language and cultural revitalization gatherings.

Addressing Measurement Error Bias in Grouped Continuous Data for Causal Inferences | UW CSSS SEMINAR

SAV 409
Wednesday, June 3, 2026, 12:30 – 1:30 p.m.

Abstract:

Applied researchers often analyze ordered categories that discretize continuous quantities (income, time frequencies, biomarkers, exposures). Treating such indices as continuous or imputing bin midpoints are convenient but misleading strategies to estimate marginal effects in regression analyses. This paper characterizes a form of measurement error that arises in those strategies by design, from the sampling mechanism, which induces biased and inconsistent estimations that are model-dependent and a priori unpredictable. I provide a solution to this problem, a calibration method - regularized interval regression - that treats responses as intervals of a latent distribution, and predicts calibrated proxies robust to measurement error biases in downstream linear regressions. Monte Carlo evidence shows that, relative to midpoint imputation and “ordinal-as-continuous,” the calibrated proxy yields unbiased linear estimates, especially in the presence of right-censoring/top-coding. An example based on survey income data illustrates the source of this measurement error but the approach generalizes to any grouped-continuous ordinal variables and has direct implications for observational and experimental designs that rely on ordinal treatment measurements.

Ramses is a Ph.D. candidate in the department of Political Science, and research assistant at the CS&SS consulting service. His research interests are in political economy and methodology.
