Naoki Hiratani, Ph.D. — Principal investigator
Naoki Hiratani is an Assistant Professor at the Department of Neuroscience at Washington University in St Louis. He was previously a Swartz Postdoctoral Fellow in Haim Sompolinsky lab at the Center for Brain Science, Harvard University, working on the neural mechanism of structured knowledge processing, and synaptic credit assignment in the mammalian cerebellum and the octopus vertical lobe. Before that, he was a Research Assistant/Fellow in Peter Latham lab at the Gatsby Computational Neuroscience Unit, UCL, where he studied the development and evolution of olfactory systems, perturbation-based learning of deep neural networks, and behavioral analysis of the International Brain Laboratory experiment. He obtained his Ph.D. from the University of Tokyo for his work in Tomoki Fukai lab at RIKEN Brain Science Institute on phenomenological and normative models of dendritic synaptic plasticity and learning in recurrent neural networks.
Pan Ye-Li — Postdoctoral Research Associate
Pan Ye-Li is a postdoctoral research associate in the Hiratani lab, where he investigates how information about time, space, and objects is integrated into episodic memories in the brain through mathematical modeling of hippocampal neuronal data. He got his Ph.D. in Mathematics from the Autonomous University of Barcelona under the supervision of Dr. Alex Roxin, focusing on modeling a novel plasticity rule found in mice hippocampus called the Behavioral Timescale Synaptic Plasticity.

Fatih Sogukpinar — Postdoctoral Research Associate
Fatih Sogukpinar is a postdoctoral research associate in Hiratani lab, where he is planning to work on theoretical foundations of biological and artificial neural networks. He obtained his Ph.D. from Washington University in St Louis, department of Electrical & Systems Engineering, for his work in Monosov lab on computational modeling of human information seeking and reinforcement learning, and astrocytes’ role on reinforcement learning in mice. He obtained his undergraduate degree from Bogazici University, Turkey, in Electrical & Electronics Engineering and Physics. He is curious about many areas of science and philosophy. When he is not working, he is likely playing chess, playing the violin, or watching thrilling documentaries.
