Rahnev is an associate professor in the \u003Ca href=\u0022https:\/\/psychology.gatech.edu\/\u0022\u003ESchool of Psychology\u003C\/a\u003E at Georgia Tech. After finishing his Bachelor\u0026rsquo;s degree in Psychology at Harvard University, Rahnev obtained his Ph.D. at Columbia University with Hakwan Lau and completed a postdoctoral fellowship at UC Berkeley with Mark D\u0026rsquo;Esposito.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ERahnev\u0026rsquo;s research seeks to uncover the computational and neural bases of perceptual decision making.

In another influential line of studies, Rahnev used a combination of brain stimulation and neuroimaging to demonstrate the existence of a hierarchical structure in the prefrontal cortex such that progressively rostral regions control later stages of perceptual decision making.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EHis more recent work has uncovered the sources of suboptimality in perceptual decision making and developed improved models of visual metacognition.\u003C\/p\u003E\r\n\r\n\u003Cp\u003ERahnev has received an impressive series of grants from NIH, NSF, and the Office of Naval Research and mentored many graduate students and postdocs.
