Welcome to my homepage!
I am a Applied Science Lead/ Manager at Amazon Ads, and I am skilled in formulating the machine learning problems and prototyping scalable solutions. Before that, I worked as Sr. Applied Research Scientist at Amazon Search (A9.com) QU team from 2018 to Sep, 2022. I received my PhD degree in Systems Engineering (Cyber-physical Systems) from University of California Berkeley, College of Engineering in May 2018, under supervision of Professor Alexei Pozdnoukhov. Before coming to Berkeley, I obtained my B.S. degree in Urban Science and secondary B.A. degree in Economics at Peking University in June 2014.

My chinese name 丹青 has its special meaning. On its wikipedia page: In Chinese painting, danqing (Chinese: 丹青; pinyin: dān qīng) refers to paintings on silk and Xuan paper. Danqing is painted with an ink brush, color ink, or Chinese pigments using natural plant, mineral, and both metal pigments and pigment blends. Danqing literally means "red and blue-green" in Chinese, or more academically, "vermillion and cyan"; they are two of the most used colors in ancient Chinese painting.
