This week, the Johns Hopkins Bloomberg School of Public Health is holding its spring graduation ceremonies. Today, Caitlin Ceryes, a soon-to-be PhD in Environmental Health and Engineering, talks with Dr. Josh Sharfstein about what led her to a career in public health, her diverse research ranging from soda taxes to sustainable aquaculture, and how the pandemic caused her to pivot her dissertation work to focus on COVID-19 occupational hazards for essential food workers.
