About Me

I have joined Kuaishou(HK.1024) as the Head of Recommendation (VP of Engineering) since June 2020, overseeing both core modeling and data mining teams. I manage and lead 100+ engineers and scientists to develop machine learning models that power Kuaishou's recommendation and ads engines in all major services, including domestic products (Kuaishou and Kuaishou Express) and international products (Kwai). We are one of the world's leading short-video content communities and social platforms with 1 billion monthly active users, and still growing at a tremendous speed (Bloomberg, Forbes). I'm also actively oraganizing academic conferences and have served as PC&Area Chairs in Recsys, WSDM, TheWebConf(WWW), IEEE Big Data etc.

I was a Research&Engineering Manager in the Deep Dialogue group of Machine Intelligence in Google AI, working on building the world's best dialogue engines for Google products using deep learning, NLP and recommender systems. Before that, I was a Senior Software Engineer at Google Seattle working on user modeling and machine learning for Ads.

I spent over 7 years at Microsoft Research before joining Google. I was a Researcher at the Deep Learning Technology Center at Microsoft Research Redmond. Before that, I was a Researcher affiliated with Internet Services Research Center (ISRC)Search Quality & Cyber-Intelligene Lab (SQ-CIL) in MSR Redmond. I joined MSR in 2009 after I got my Ph.D. During my Ph.D, I worked with my advisor C. Lee Giles on the next generation scientific literature search engine CiteSeer, which was once the world most popular search engines for scientific literature [screenshot].

Here is the link to my Google Scholar page.

[new]The first comprehensive book about query understanding for search engines has been published. We co-authored the chapter of query suggestions.

We have recently open-sourced our code that implemented Multi-view DNN and Temporal DSSM in Keras [github link].
