Biography
Matthew Ponticiello (he/him) is an MD PhD student pursuing his PhD in Epidemiology of Microbial Diseases through the Yale School of Public Health. His research interests include implementation science, LGBTQ health, the treatment of opioid use disorder in criminal legal settings, and mood disorders. Matt is particularly interested in using mixed methods research to improve the uptake of evidence-based care. He is currently living in Lima, Peru working on his dissertation studying barriers and facilitators to and preferences for PrEP delivery among men who have sex with men in Lima, Peru.
Matt earned his B.S. in Global and Public Health Sciences at Cornell University. He then worked at the Weill Cornell Center for Global Health under Dr. Radhika Sundararajan. There, his research focused on community-based interventions to improve the uptake of HIV care among medically pluralistic communities. The majority of Matt's work was spent studying novel methods to improve the uptake of HIV care by collaborating with traditional healers in Uganda and Tanzania. Matt also contributed to the development of a community health worker-delivered gestational diabetes screening program in Pune, India.
