Convenors: Werner Schneider (Bielefeld, GER), Helge Ritter (Bielefeld, GER)
Professor Charan Ranganath received his undergraduate degree in psychology from UC Berkeley in 1993. He received his Ph.D. in Clinical Psychology from Northwestern University in 1999, and was a postdoctoral fellow at the University of Pennsylvania and UC Berkeley from 1999 to 2002. Since 2002, he has been a faculty member of the Psychology Department and the Center for Neuroscience at the University of California at Davis, and he has been a Full Professor since 2010.
Dr. Ranganath studies the neural basis of episodic memory, and the role of cortico-hippocampal networks in processing of complex events. He was recognized as a Visiting Fellow at the University of Cambridge, UK, a UCSB Sage Center Distinguished Fellow, and he received the Samuel Sutton Award for Distinguished Scientific Contribution to Human ERPs and Cognition, Cognitive Neuroscience Society Young Investigator Award, DoD Vannevar Bush Faculty Fellowship Award, and a Guggenheim fellowship.
Current Main Research Interests
My lab uses neuroimaging, electroencephalography, and computational modeling to understand the neural basis of episodic memory in healthy individuals and in those with brain damage. We are currently investigating how different cortico-hippocampal networks represent different aspects of complex events experienced in videos, stories, and virtual reality experiences in real time, and during episodic memory retrieval. We also are investigating how memories for complex events are affected by sleep-dependent consolidation processes.
