5th Year
B.A. Connecticut College

My current research interests focus on understanding cognitive functioning in individuals with substance use disorders.  In an effort to more accurately characterize the drug-abusing population, my research uses a multidisciplinary approach by combining neuropsychopharmacology and social psychology. I am also interested in how public perceptions of individuals with substance use disorders shape drug policy.

J.D. Harvard University

Michael J. Naft is a third-year doctoral student working with Geraldine Downey. Prior to coming to Columbia, Mike worked as the general counsel of a hedge fund based in New York City, as a white-collar criminal defense attorney, and most recently as a lab manager for Valerie Purdie-Vaughns. Mike is interested in pursuing research related to institutional bias, decision-making, and moral psychology. He hopes to explore the implications of his work in these areas on questions of justice and ethics across a variety of domains, including law, business, and medicine. Mike received his JD, cum laude, from Harvard Law School, and his BA, summa cum laude, in Philosophy, from Emory University, where he was elected to Phi Beta Kappa. He served as a law clerk or the Honorable Constance Baker Motley of the U.S. District Court for the Southern District of New York.


1st Year
B.A. University of Wisconsin-Milwaukee

Christopher graduated from the University of Wisconsin-Milwaukee, magna cum laude, with a B.A. in Psychology. As an undergraduate, he was a McNair Scholar and conducted research in the Brain Imaging and Neuropsychology (BraIN) Laboratory, as well as with the Milwaukee County Drug Treatment Court evaluation team. Through this work, he began to notice how misinformation about the neuropharmocological actions of drugs have contributed to the phenomenon of mass incarceration. This inspired him to gain a more thorough understanding of the neurobiological and environmental factors that determine response to drug effects.
