I am an associate professor in the Computer Science and Engineering Department and the Institute for Computational and Data Sciences (ICDS) at the State University of New York (SUNY) at Buffalo. I completed my PhD from University of Minnesota, Department of Computer Science. My research is in the area of scalable anomaly detection and data mining for big graphs, temporal, and spatial data.

I lead the UB data science research group. I am also affiliated with the The Center for Hybrid Rocket Exascale Simulation Technology (CHREST) and the The Computer Science for Social Good (CS4G) group at UB. I am also the director of the ICDS/CDSE PhD program.

I am on a temporary leave from UB for next few years, and will be serving as a Program Director in the Office of Advanced Cyberinfrastructure, at the National Science Foundation. I will not be taking any new students until then.
