Thank you for visiting this website! I am a demographer. I was a David E. Bell Fellow at the Harvard Center for Population and Development Studies (2022-23). I have a PhD in Demography and Sociology from the University of Pennsylvania. My research focuses on empirical measurement of mortality, as well as social and environmental determinants of health. It uses both demographic and field methods. You can access it here. The photo below is from rural Mymensingh, Bangladesh. A teddy bear dries in the sun, after a shower, suspended with a string tied to its ear. Without it, this page was a bit bland.
