AI Executive Leader

As an executive AI leader, I help organizations build AI teams, shape AI mindsets, and form product visions and strategies around AI-first principles. I specialize in Search, Recommendation & Advertising for Modern Marketplaces (e.g., Jobs, E-commerce, etc.) and have deep experience transforming AI solutions into business upsides.

Currently, I am Director of Engineering, AI at LinkedIn, Head of Talent Marketplace AI team, which comprises nearly 60 ML engineers and applied researchers. I am responsible for overseeing multi-billion-dollar impact for LinkedIn Talent business and empower millions of job seekers find next plays. Our team owns both the organic and paid experiences for job search, recommendation and notification product domains, which creates unique opportunities to drive innovations from a holistic point of view.

Prior to joining LinkedIn, I served as a Director of Data Science and Machine Learning at Etsy, where I was instrumental in growing a team of five members to an organization of 40 data scientists and machine learning engineers, with teams in New York City and San Francisco. The centralized organization I developed delivered critical machine learning solutions on Etsy’s search and recommendation products, contributing to its early success in applying AI to products. Before Etsy, I worked as a Senior Manager of Research at Yahoo Research from 2013 to 2016. I hold a Ph.D. (2013), M.S. (2010) from Lehigh University and B.S. (2007) from Beijing University of Chemical Technology, all in Computer Science.

In addition to these roles, as an industrial researcher, I co-authored papers in all major international conferences in data mining and applied machine learning including SIGIR, WWW, KDD, CIKM, AAAI, WSDM, RecSys, and ICML with more than 6,200 citations (H-index: 28), winning multiple paper awards (WWW 2011, WSDM 2023, RecSys 2014). I also regularly serve as senior or regular program committee members in KDDWWW, SIGIR, WSDM, AAAIEMNLP, ICWSM, ACL, CIKM, IJCAI as well as constantly reviewing articles in most prestigious journals such as DMKD, TKDD, TIST, TOIS, and TKDE. Previously, I co-organized several tutorials on user engagement metrics and optimization topics at WWW 2019, WSDM 2018, KDD 2014, and CIKM 2013. More recently, I co-organized workshops on computational jobs marketplace on KDD 2022 and WSDM 2022.
