Tan Pei Sze | National Institute of Informatics, Japan

About Me

I am a Postdoctoral Fellow in Echizen Lab, National Institute of Informatics, Japan. Also, I studied my doctoral studies at Monash University Malaysia, supervised by Professor Raphael Phan, Dr Sailaja Rajanala and Dr Ong Huey Fang. I graduated from Xidian University in 2022 with a Bachelor’s degree in Communication Engineering. Malaysian born and raised. Grew up in Klang (aka Bak Kut Teh land). IC says Banting—no complaints, both got good vibes.

Research Interests
