These features arise naturally in education, public health, policy evaluation, and many other fields, but they also complicate causal estimation and inference by undermining the validity for familiar estimators and standard errors.\n\nThe first part of the dissertation studies clustered randomized trials with heterogeneous cluster sizes. We show that the commonly used estimators that average stratum-specific treatment-control contrasts can be inconsistent for the average treatment effect in such settings, a problem that has received limited attention. We establish consistency of a simple alternative, the H\u00e1jek estimator, under standard asymptotic regimes, develop an asymptotically conservative variance estimator valid under arbitrary stratum sizes, and propose a score-type test with improved small- to moderate-sample performance.\n\nThe second part of the dissertation extends this framework to multi-arm stratified clustered experiments, where inference must account for not only treatment-versus-control comparisons, but also comparisons among active treatments. We show that regression adjustment admits a unified two-stage representation, allowing adjustment models to be fit on the full sample, a subset of units, or external data. We establish multivariate asymptotic theory for vectors of covariate-adjusted H\u00e1jek estimators and develop a covariance matrix estimator that is asymptotically conservative in the positive semidefinite order.\n\nThe third part of the dissertation connects design-based inference for randomized experiments with matched and stratified observational studies. We compare the observational assignment mechanism to an emulated stratified clustered randomized trial with the same realized blocking structure. Assuming sufficient within-block homogeneity in treatment propensities, we show that a sandwich-type variance estimator for the covariate-adjusted H\u00e1jek estimator is asymptotically conservative.\n\nTogether, these results provide a unified design-based framework for estimation and inference in randomized and observational comparative studies. The dissertation contributes both diagnostic insight, showing when common estimators fail, and constructive methodology for valid causal inference in complex empirical designs.", "occurrence_notes":null, "guid":"148339-21903956@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148339", "building_id":"1000167", "building_name":"West Hall", "campus_maps_id":"163", "room":"438", "location_name":"West Hall", "has_livestream":0, "cost":"", "tags":["Dissertation"], "website":"", "sponsors":[ { "group_name":"Department of Statistics Dissertation Defenses", "group_id":"4045", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21903956 } , "147712-21901642": { "datetime_modified":"20260603T183057", "datetime_start":"20260603T140000", "datetime_end":"20260603T150000", "has_end_time":1, "date_start":"2026-06-03", "date_end":"2026-06-03", "time_start":"14:00:00", "time_end":"15:00:00", "time_zone":"America\/Detroit", "event_title":"Resume Lab", "occurrence_title":"", "combined_title":"Resume Lab", "event_subtitle":"", "event_type":"Careers \/ Jobs", "event_type_id":"2", "description":"*RSVP required to attend.

But what about the weevil?\n\nThis talk responds to environmental scholar Malcolm Ferdinand\u2019s call to also look at the weevil in this dramatic story.\n\nBoisseron is the author of \u201cCreole Renegades: Rhetoric of Betrayal and Guilt in the Caribbean Diaspora\u201d (2014) and \u201cAfro-Dog: Blackness and the Animal Question\u201d (2018).\n\nHer current book project focuses on food repurposing and was supported by a Guggenheim Fellowship, alongside additional funding for her broader work on repurposing practices.\n\nHer recent publications examine pesticide contamination on banana plantations in the French Antilles.\n\nIn Winter 2024, Boisseron taught Food Literacy for All as a faculty instructor and is a Sustainable Food Systems Initiative Affiliate.\n\nThe University of Michigan Biological Station serves as a gathering place to learn from the natural world, advance research and education, and inspire action.
