Areas of Interest: 

Brian’s current research interests include better characterizing the clinical course and consequences of anemia and secondary hyperparathyroidism in patients with chronic kidney disease; methods for conducting post-marketing drug surveillance studies; longitudinal data analysis using large databases; and application of methods for controlling time-dependent confounding and confounding-by-indication in studies of treatment effects.

Brian D. Bradbury, MA, DSC, is currently an Adjunct Associate Professor in the Department of Epidemiology and Director in the Center for Observational Research at Amgen, Inc. leading the epidemiologic research program for medications used in the treatment of patients with kidney disease. Brian received his Doctor of Science in Epidemiology from Boston University in 2004 and a Master of Arts in Education & Psychology from Pepperdine University in 1998. Brian currently teaches the Introduction to Pharmacoepidemiology course (EPI 268). Before joining Amgen, he worked at the Boston Collaborative Drug Surveillance Program (BCDSP) conducting and publishing post-marketing drug surveillance studies. He has authored or co-authored various peer-reviewed publications in the areas of pharmacoepidemiology, cancer epidemiology and methods for controlling confounding-by-indication.
