Societal Computing research · Deputy Head (Information Management), DSTA Singapore · Principal Investigator, The LAN Shop
I study how AI agents (bots) and humans interact in online communities, and how automated persuasion shapes those communities. My methods draw on network science, computational social science, and natural language processing.
I lead The LAN Shop — Language, Agents, and Networks — at the Information Programme Center, DSTA, Singapore. I obtained my PhD in Societal Computing from the Department of Computer Science at Carnegie Mellon University, advised by Prof. Kathleen Carley, where I received the Best Dissertation Award, for the foundational impact and influence of my research. I received my B.Comp. from the Department of Computer Science, National University of Singapore, where I was awarded the NUSS Medal for Outstanding Achievement.

I was born with hypertrophic cardiomyopathy and lived with it for 29 years, including two pacemakers, before receiving a heart transplant at UPMC Presbyterian in March 2023. It's a whirlwind story I'm still writing — read and subscribe here.
Outside of research, I play violin with the Pittsburgh Philharmonic Orchestra and love exploring Pittsburgh and the wider United States. Some of that shows up on my Instagram, which has been featured by CMU's School of Computing.
