I am a demographer and epidemiologist. I study the social, economic, political, and biological determinants of health, mortality, health disparities, and aging.  

I am the Chief Epidemiologist at the Philadelphia Department of Public Health.  I received my PhD in Demography and Public Affairs in 2015 from Princeton's Office of Population Research and School of Public and International Affairs. 

You can occasionally find me on Twitter or LinkedIn.
