Pongpat Putthinun, PhD

Postdoctoral Fellow

Pongpat Putthinun is a health economist and postdoctoral scholar in the UCSF Memory and Aging Center. He joined the Decision Lab team, led by Dr. Winston Chiong, and is currently working on a project aimed at understanding how genetic predispositions to frontotemporal dementia influence decision-making in the pre-symptomatic phase. Through neuroeconomic methods, the research seeks to identify incidents of early impaired judgment that could lead to early intervention strategies to decelerate the onset of frontotemporal dementia.
