Talks
Presentations with files to view or download; most are tied to my papers. Conference talks are listed on the CV.
JHU Biostatistics Retreat Presentation, October 2, 2026
How to adjust for disease severity when it is not measured. A proxy built from the age at disease onset and the current age carries similar information, but the age at onset is right-censored. The page sets up the statistical problem and shows simulation results for the complete case and IPW estimators across censoring rates.
COMPSTAT 2026, Athens, Greece, August 27, 2026
Talk on Huntington disease data where the age at onset is right-censored and censoring depends on the outcome. The talk compares estimators across censoring rates and shows that choosing the estimator to match the censoring rate improves inference.
International Biometric Conference, Seoul, South Korea, July 14, 2026
Talk on federated learning when each site has missing data, motivated by pleural infection outcomes across hospitals. The talk covers when the complete case estimator is enough and when a weighted estimator is needed, and how to correct its variance.
CIDI T32 Meeting, Johns Hopkins, March 10, 2026
A lecture for the CIDI T32 trainees on federated learning when sites have missing data. The slides introduce distributed research networks and the COLA-GLM estimator, which assumes complete data, and then develop a weighted version for missing covariates, with simulation results on bias, coverage, and the variance correction. The example comes from pleural infection data at two sources.
Stuart Lab Meeting, Johns Hopkins Biostatistics, November 4, 2025
Slides on the values that guide how the lab works together: a mindset of improving the lab, engaging in lab meetings and operations, sharing skills through workshops and co-working sessions, and building community by supporting each other. The slides close with a prompt for each member to propose a team agreement.
