Halo~! My name is Jiexin, you can also call me Judy.

I am currently a postdoctoral researcher working with Dr. Eiji Uchibe in the Department of Brain Robot Interface at ATR Computational Neuroscience Laboratories.

I completed my PhD under the supervisions of Prof. Shin Ishii at the Integrated Systems Biology Lab, Grad School of Informatics, Kyoto University, and Prof. Kenji Doya in the Adaptive Systems Group, Neural Computation Unit, Okinawa Institute of Science and Technology (OIST).

During my Phd, I developed an affordable and sustainable smartphone robotic platform to investigate artificial intelligence, focusing primarily on building Reinforcement Learning (RL) methods to better understand animal and human behaviors.

My current research examines how separating reward and pain, distinct from traditional RL reward frameworks, can enhance exploration and improve sample efficiency and robustness within RL and Deep Reinforcement Learning (DRL) frameworks.

Outside of my research, I am a mountain climber at the pre-alpinist level.
