Dr. Dore is a pharmacoepidemiologist who specializes in studying the post-marketing safety and effectiveness of medical products as they are used in customary clinical practice. He has over 15 years of experience with regulated post-approval safety studies (PASS) conducted with secondary data sources (e.g., healthcare claims), and he has developed expertise in novel data linkages and supplementary data collection to address biases in these studies. Additionally, Dr. Dore specializes in research applications of large electronic health records (EHR) systems, which typically include a myriad of data types from various health systems. This work has included evaluating and improving the quality of complex EHR data, conducting applied research that involves the use of free-text clinical notes and methods to address missing data, and the design of pragmatic randomized trials. Dr. Dore has been on the faculty at the Brown University School of Public Health since 2008.
