About

I am a software engineer at Google Search NYC (2019 - present) with a research background in Human-Computer Interaction and Computational Social Science. My engineering work improves search dialog quality with better ranking and query understanding. My research focuses on articulating how AI increasingly mediates social exchange and its societal impact on trust. Previously I worked at Facebook Core Data Science (2018) on trust in social groups and Airbnb (2016) on trust in host profiles. I run the NYC Computational Social Science happy hour series pre-pandemic. I also attempt to write about social computing in the wild on substack.

Education

I hold a PhD in Information Science from Cornell (NYC campus) on the topic of Networked Trust: Computational Understanding of Interpersonal Trust Online. I was lucky enough to be advised by Mor Naaman, Karen Levy, Serge Belongie, and Jeff Hancock. Before coming to the U.S., I completed my bachelor's in Electronics Engineering at Peking University (2010-2014) in Beijing. I have also spent time at Technion (2012) and Stanford (2016) as a visiting student researcher.

Art

As a New Yorker, I am always looking to support (through donation and technical volunteering) local cultural institutions that promote diversity in the intersection of art and technology, e.g., National Sawdust and Rhizome. Please reach out if you have other ideas.
