I am the VP of Technology at Petuum, Inc., a startup for datacenter-scale Artificial Intelligence and Machine Learning operating systems, and analytical software for enterprises. Previously, I was Lab Head and Principal Investigator for Distributed Analytics at the Institute for Infocomm Research, A*STAR, Singapore. I hold an adjunct Assistant Professor position at the Singapore Management University School of Information Systems. I received my PhD in 2014, under Eric P. Xing at Carnegie Mellon University's Machine Learning Department. My research focuses on distributed cluster software systems for Machine Learning at Big Data and Big Model scales, with a view towards theoretical correctness and performance guarantees, as well as practical needs like robustness, programmability and usability. I also work on statistical models for large-scale network analysis and social media, including latent space models for visualization, community detection, user personalization and interest prediction.
