Marisa L. Henry is a PhD student in the Department of Environmental Health & Engineering at Johns Hopkins University and a graduate research assistant with the Environmental Program Innovations Collaborative (EPIC) directed by Dr. Paul Ferraro. She is interested in interdisciplinary research applying insights from behavioral science to create evidence-based policies, programs, and technologies for social and environmental good. She has worked on projects including estimating the causal effect of electronic home energy reports on residential electricity consumption; designing and testing a prototype thermal cooker to reduce household air pollution in rural Peru; and is currently working on the design and implementation of a field experiment to estimate the effect of peer comparisons on polluting facilities. While completing her PhD, Marisa is also pursuing an MSE in applied mathematics & statistics from Hopkins and serves as an advisor to an Engineers Without Borders team. Marisa holds a BS in environmental & ecological engineering from Purdue University and an MPhil in engineering for sustainable development from the University of Cambridge, where she was a 2016 Gates Cambridge Scholar.
