Professional Interests:

I use data science to help clinical and health services researchers from a vast spectrum of disciplines and specialties which has resulted in 250 publications. The majority of these projects involve comparative effectiveness, clinical trials, association studies, and prediction modeling. I am especially interested in survival (aka, time-to-event) analysis, causal inference and most recently the decline in American longevity.



Courses Taught:

QBS 121: Biostatistics II; a course in statistical modelling (Winter) with Tor Tosteson




Past Teaching:
PH 271 (TDI) "Practice of Statistics in Medicine" with James O'Malley: This course was aimed at junior faculty, post-doctoral fellows and PhD students.


PH 147 (TDI) "Advanced Methods in Health Services Research" with Tracy Onega

PEMM 107 "Biostatistics" : A course in biostatistics I developed for bench and translational scientists in molecular medicine.
