Lester Rodriguez Santos, BSc (Hon)

Lester earned a B.S. in Cellular and Molecular Biology from the University of Puerto Rico, Río Piedras Campus in San Juan, Puerto Rico. As an undergraduate, he conducted research using pre-clinical rodent models to investigate the role of endocannabinoids in regulating anxiety-like behaviors.

Following graduation, he joined the Neuroimaging Research Branch at the National Institute on Drug Abuse as a postbaccalaureate fellow under the mentorship of Dr. Elliot Stein. His work focused on examining alterations in functional connectivity during acute nicotine abstinence in smokers.

At Yale, Lester is co-mentored by Dr. Sarah W Yip and Dr. Kelly Cosgrove. His research focuses on examining how acute stimulant drug administration affects brain function and behavior, using functional magnetic resonance imaging (fMRI) and positron emission tomography (PET).

In addition to his research, Lester is committed to scientific outreach and education. He currently serves as Director of OpenLabs at Yale, a student-led initiative that hosts science outreach events on campus each semester. He also works as an Outreach and Education Fellow for Yale Pathways to Science, at Yale’s Office of New Haven Affairs, where he supports efforts to expand access to STEM careers for local students through educational opportunities at Yale.
