About Me

I am an Associate Professor of Statistics at The Ohio State University (OSU). I am also the co-director of the community of practice on foundations of data science and AI at the Translational Data Analytics Institute (TDAI). My current research has two focus areas: (1) network analysis, including multilayer and temporal networks, network time series, and peer effect estimation, problems, (2) heterogeneous transfer learning and privacy-preserving federated learning under the general theme of statistical foundations of AI. I am interested in interdisciplinary collaborations, and in the past, I have collaborated with researchers in Computer Science, Neuroscience, Microbiology, Psychology, and Economics. My research has been funded by a joint NSF-NGIA grant from the Algorithms for Threat Detection program.
