Chen Scholars

Headshot Yuki Oka

Yuki Oka

Assistant Professor of Biology and Chen Scholar
B.A., The University of Tokyo, 2002; Ph.D., 2007. Caltech, 2014; Chen Scholar, 2019.

The long-term goal of Dr. Oka's research is to understand how the brain integrates internal body state and external sensory information to maintain the balance in the body. In particular, his lab investigates various aspects of homeostatic regulation and innate behavior including (1) thirst and satiation mechanisms, (2) short- and long-term appetite regulation, and (3) interaction among peripheral, interoceptive, and neural signaling.

Dean Mobbs

Assistant Professor of Cognitive Neuroscience and Chen Scholar
B.S., University of Birmingham, 1999; Ph.D., University College London, 2008. Assistant Professor, Caltech, 2016; Chen Scholar, 2019.

Dr. Mobbs studies what happens in our brains when we interact with others and when we are under threat. Using brain-imaging, computational modeling and behavioral techniques, his lab is probing the neurobiological systems responsible for fear and anxiety, revealing how people learn to control their fears, and how anxiety and psychiatric disorders disrupt those processes. He's interested in the value of social behavior. His research also focuses on the interplay between social interaction and emotion—how fear can depend on whether you're alone or in a group (e.g. risk dilution).
