Chien Liu

My name is Chien Liu

I grew up in Taiwan, and now studying M.A. Computational Science and Engineering in University of Rostock, Germany. I worked as a data scientist and machine learning engineer. In the past 6 months, I worked with Teraki in Berlin, developing radar processing algorithms. When I'm not coding, I enjoy cooking, playing board games and badminton.
