I am the Associate Dean of Academic Affairs, Director of the BSPH program, Associate Professor in Biostatistics and Vice Chair of Education in Biostatistics at the University of Pittsburgh, School of Public Health. I am also Senior Biostatistician in the Center for Health Equity Research and Promotion (CHERP) Biostatistics and Informatics Core at the VA Pittsburgh Healthcare System. In my roles as Principal Investigator, Co-Investigator, and Lead Biostatistician, I have primary responsibility for statistical integrity, including conceptualization, design, and grant development, recruitment/data collection, monitoring, analysis, reporting, and manuscript preparation. My primary area of statistical expertise is regression modeling with extensive experience analyzing big data from large administrative data systems as well as prospective clinical trials and epidemiological studies involving time to event modeling and mixed effects modeling. I have maintained successful research collaborations most recently with VA investigators. In my roles as Educator and Mentor, I teach courses in introductory biostatistics, applied regression analysis, scientific communication skills, mathematical methods for statistics, and mixed models as well as direct the MS Capstone in Biostatistics. I have mentored over 100 students, fellows and early career faculty and 36% of my peer-reviewed publications are with mentees.
