What sparked your decision to become an epidemiologist?
I gravitated towards science as an undergraduate because I enjoyed devising studies to test my ideas about how the natural world worked. However, I found that doing biological research did not connect as closely as I would have liked to the topics that were most important to me. I grew up in Baltimore, a city facing severe problems with racial segregation, poverty, violence, and substance use. I was motivated to better understand how Baltimore and many other US cities had developed into these sorts of situations, and how these conditions were impacting the people who lived there. During my senior year, to satisfy a statistics requirement for my biology major, my advisor Anne Fausto-Sterling recommended that I take something called “epidemiology”. I truly had no idea what it was. Sally Zierler taught the introductory epidemiology course at Brown at that time, and many of the example studies in the course related to social determinants of health. This was an eye-opening experience because it revealed that the scientific method that had drawn me to biology could be applied to the social issues that I was motivated to better understand. I quickly shifted from marine biology and oceanography to epidemiology and public health when planning for next steps after graduation. That is how I ended up on the path to epidemiology.
