About Me

Currently I'm a PhD candidate in the College of Information Science and Technology, Pennsylvania State University. Advised by Dr. Zhenhui (Jessie) Li, I'm mainly interested in the field of Data Mining, especially spatio-temporal data mining. Before joining Penn State in 2017, I received my master and bachelor degree from Beihang University (BUAA) majoring in Computer Science, working with Prof. Jinpeng Huai and Dr. Tianyu Wo.

I've always been excited about real-world applications in industry. I interned at DiDi Research for 9 months working with Dr. Pinghua Gong and Prof. Jieping Ye on building online and offline models for carpooling recommendation, payment habits prediction and subsidy optimization. I also interned at Microsoft Asia-Pacific Research & Development Group as an intern working on integrating knowledge-based question answering methods into Microsoft's chatbot - XiaoIce. Supervised by Yue Liu, I also work with Dr. Nan Duan in MSRA on end-to-end answer prediction.

Last year, I had an exciting internship in Hangzhou City Brain Research with my advisor, working on intelligent transportation, epscially using reinforcement learning for traffic signal control.
