Xiao Ma


I am a Machine Learning research engineer at Google (2019 - present) with a background in Human-Computer Interaction (HCI). I currently work on Large Language Model (LLM) safety and human-ML collaboration.

My prior research focuses on understanding 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 hold a PhD in Information Science from Cornell (NYC campus) on 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 U.S., I completed my bachelor's in Electronics Engineering at Peking University (2010-2014) in Beijing.


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 to pitch an idea. I also make art under the name Maximal Margin.


Happy to talk about responsible Machine Learning, HCI, art, diversity, and food. If you send me an email with concrete questions, I will try my best to reply.
