Bayesian Semiparametric Estimation of Heterogeneous Effects in Case-Control Studies with an Application to Emergency Department Visits and Home Medication Use
Nov 2023 – May 2024
Incorporated Bayesian additive regression trees (BART) into the conditional logistic regression model to identify heterogeneous effects of home medication use exposures in a case-crossover design.
Applied conditional logistic BART (CL-BART) to a study of the impact of home medication use on patient-level ED visits from five Emory Healthcare hospitals within the Atlanta Metropolitan area during the warm season (May to September) from 2013 to 2019 and effect modification by other chronic conditions.
Conducted a comparative analysis by stratifying data based on home medication usage, revealing heightened correlations between daily maximum temperature and emergency department (ED) visits.

Multicenter Trial of Stem Cell Therapy for Osteoarthritis
Aug 2023 – May 2024
Identify a superior stem cell source for osteoarthritis treatment by comparing four treatment groups using statistical methods (LDA, cLDA, ANCOVA, survival analysis) and models (LDA, cross-sectional) in SAS and R.
Generated publication-ready tabular and graphical summaries for manuscript inclusion, including outcomes such as visual analog score (VAS) pain score, knee injury and osteoarthritis outcome (KOOS) score.

Risk Factor Analysis for Multimorbidity across Age Groups in the U.S.
May 2023 – Sep 2023
Harmonized and bridged national longitudinal data from 7 nationwide datasets to track the incidence of chronic diseases and multimorbidity in the U.S. starting at age 30 using R, Stata, and Excel.
Drafted comprehensive analysis plans, authored in-depth specifications for analysis files, performed statistical analyses, interpreted findings, and maintained the analytical rigor of the study.
Incorporated 7 national longitudinal datasets encompassing over 135K participants to study the various associations among chronic conditions, their risk factors, and morbidity rates at multiple time-points.
