Clifton Dassuncao

Dr. Clifton Dassuncao is an epidemiologist whose career has focused on understanding and mitigating human exposures to harmful contaminants in the environment. He has a strong background in research methods and biostatistics developed during his doctoral and post-doctoral training, where he built models to better understand the fate, transport, bioaccumulation, and human exposures of emerging contaminants.

At ERG, Clifton has supported federal, state, and not-for-profit clients in conducting exposure assessments, risk evaluations, toxicological reviews, and epidemiological studies covering a wide range of emerging concerns including PFAS and COVID-19. Clifton has become a leader in wastewater-based epidemiology, an emerging public health tool used to determine exposure to chemicals or pathogens in a community. He supports a diverse set of projects that monitor for drugs and SARS-CoV-2 (the virus that causes COVID-19) in wastewater.

Clifton holds an Sc.D. and M.S. in environmental health from the Harvard T.H. Chan School of Public Health and a B.S. in civil and environmental engineering from the Massachusetts Institute of Technology.
