Lab director

HyungGoo Kim majored in Computer Science and Engineering at Seoul National University. He started his professional career as a software engineer. The limitations of intelligent agents made him interested in the brain. He joined the laboratory of Dr. Choongkil Lee in Interdisciplinary Program in Neuroscience at Seoul National University. He was further trained in visual neurophysiology, psychophysical methods, and computational modeling during his Ph.D. under the supervision of Dr. Gregory DeAngelis in Brain and Cognitive Sciences at the University of Rochester. He then switched from NHP to mice and joined the laboratory of Dr. Naoshige Uchida in Molecular and Cellular Biology and the Center for Brain Science at Harvard University to study dopamine system. His long-term goal is to elucidate learning mechanisms in the brain that can be adapted to improve artificial intelligence.

Graduate students

Jihye Yang

Jihye has an interest in dopamine dynamics while association and dissociation occur in the brain. Through studying correlations between neural activity and behavior, she pursues a feasible method to help people who suffer from memories with unpleasant emotions evoked, such as PTSD. Since she received her bachelor’s degree in Molecular Bioscience, she ideally wishes to integrate her knowledge of molecular neuroscience with circuitry or behavioral level in a computational way. This lab makes Yang fascinated with state-of-the-art techniques for analyzing dopamine activities corresponding to behaviors - which deepens her understanding of various dopamine responses involved in Reward Prediction Errors (RPEs) and Punishment Prediction Errors (PPEs).

Jihwan Kim

Jihwan is interested in RL and decision-making, specifically how different types of cost is integrated in learning agent’s brain. In his experience at cognitive neuroscience laboratory followed by his previous experience in behavioral research on rats, he has developed a keen interest in studying neural mechanisms of reinforcement learning and decision-making process in rodents. He aims to disentangle how different types of costs affect reward-processing circuit via behavioral and neural quantification of cost-benefit decision making model. Ultimately, his goal is to apply his findings during his time in NeuRLab further in both clinical and scientific research regarding different neuropsychiatric diseases characterized with reward-processing deficit. He hopes that such approach can also be in harmony with computational modeling which can be applied and generalized across different field of industries.

Ben Dougen

Ben received his bachelor’s in Neuroscience and master’s in Pharmacology at the University of Minnesota-Twin Cities working with the Carroll and Kerlin labs respectively.
