My name is Chao Wen. I’m a PhD student at the Max Planck Institute for Software Systems (MPI-SWS). I am advised by Dr. Adish Singla in the Machine Teaching Group.

I received M.Sc. in the College of Computer Science and Technology from Nanjing University of Aeronautics and Astronautics, China, advised by Prof. Xiaoyang Tan. Then I worked as an algorithm engineer at Lazada, Alibaba Group from June 2021 to July 2022.

My research interests include reinforcement learning (RL) and AI for programming education.
