Teaching
At Hopkins
330.605: Doctoral Seminar in Public Mental Health (terms 1 and 2, starting 2023)
330.636: Methods for Handling Missing Data in Psychosocial Research (summer institute, 2017-present, co-teaching with Liz Stuart). Analyses that use just the individuals for whom data is observed can lead to bias and misleading results. This course discusses types of missing data, and its implications on analyses. We covers solutions for dealing with attrition (non-response) and missingness on individual items. These solutions include weighting approaches for unit non-response and imputation approaches for item non-response. Practical implementation is emphasized, including discussion of software to implement multiple imputation. Examples come from school-based prevention research as well as drug abuse and dependence. This course has received Excellence in Teaching recognition a bunch of years.
330.805: Seminar on Statistical Methods for Mental Health – Prediction models: promises and pitfalls (term 1, 2022, co-taught with Nick Seewald). This seminar class received Excellence in Teaching recognition.
330.805: Seminar on Statistical Methods for Mental Health – Causal mediation analysis (term 2, 2021)
330.637: Causal Mediation Analysis (summer institute, 2021 and 2022, co-taught with Liz Stuart). This serves as a first course on this complex topic. We give a quick review of causal inference basics and then dive into causal mediation analysis for a simple case with a single mediator or multiple mediators considered en block. (More complex cases are touched on in extra material, but are not the focus.) We cover three steps of causal mediation analysis: (1) matching research questions to effect definitions, (2) considering assumptions required for effect identification, (3) estimating the effects.
OLD causal mediation course: I did this as a postdoc in 2015 when my understanding of causal mediation analysis was rudimentary. Here are the slides anyway, in case they are helpful to someone else. (They would have been helpful to me at that point.) [session 1] [session 2] [session 3] [session 4]
