  - Title: Causal effects conditional on post-treatment variables
  - Abstract: Many studies aim to estimate treatment effects on outcomes that are defined only for individuals who experience a post-treatment event. For example, the effect of cancer therapies on quality of life is only well defined among individuals who are alive. Similarly, the effect of vaccines on post-infection outcomes is only of interest among individuals who become infected. A naive comparison of outcomes conditional on such post-treatment events generally lacks a causal interpretation, even when treatment is randomly assigned.
  In this talk, I discuss causal contrasts for outcomes conditional on post-treatment events, including principal stratum effects and conditional separable effects. I then derive identification results for these estimands and discuss their interpretation and the conditions under which they might, in principle, be falsified. I illustrate the relevance of these results for clinical trials of cancer therapies and vaccines, and I conclude by revisiting the classical birth weight paradox in epidemiology.

  - Title: Causal Inference as a Logical Problem
  - Abstract: The goal of this talk will be to show how problems of causal inference can be usefully and precisely understood as logical problems. Adapting tools and concepts from mathematical and computational logic affords new perspectives, raises new questions, and sheds light on some practical and theoretical issues in causal inference. We illustrate with several examples, including some ways in which a logical lens can help clarify the empirical status of assumptions sufficient to bridge gaps between limited data and substantive causal conclusions.

  - Title: Stable Discovery of Treatment Effect Modifiers
  - Abstract: Identifying covariates that modify treatment effects is a critical problem in causal inference. Yet existing data-adaptive methods lack rigorous error control, risking spurious findings that fail to replicate. We propose a method combining pseudo-outcomes with a novel cross-fitted stability selection algorithm to achieve finite-sample false discovery control for effect modifiers. We prove that selection probabilities are asymptotically unbiased, converging to oracle probabilities at parametric rate under doubly robust pseudo-outcome estimation. False discovery is controlled at the nominal level while maintaining power to detect genuine heterogeneity. We demonstrate the method on simulated and real-world data.

Instructions for Attendees

You can join the webinar by clicking the link on the webpage. If you signed up to the mailing list, you will receive an email with the link before the webinar begins. On Tuesday, you should join the seminar shortly before the start time 8:30 am PT.

Please participate during the seminar!

Due to high demand, we will host the seminar as a Zoom webinar. As an attendee, you will not be able to unmute yourself. If you have questions about the content of the talk, please submit the questions using the Zoom Q&A feature. Time permitting, and depending on the volume of questions, the moderator will either ask your question for you or confirm with you to ask the question yourself and unmute you at a suitable time. In some meetings, the collaborators of the speaker will be online to address your questions in Q&A. Note that Q&A will be moderated by us so you will only be able to see some of the questions of the other attendees. If you want to send messages to the moderators during the seminar, please use the Zoom chat feature. 

Zoom instructions

If you have not used Zoom before, we highly recommend downloading and installing the Zoom client before the meeting. Additional instructions on how to use Zoom during a webinar can be found here. Note that for the online causal inference seminar, we do not require registration in advance so you will be able to join by simply clicking the link on this webpage or in the email.
