I am an assistant professor in the Department of Computer Science at the University of Iowa. My research interest lies in data mining and machine learning, with a focus on dynamical processes on large networks. My recent works include machine learning on graphs, network structure optimization, graph mining to mitigate healthcare-associated infections, mining clinical data for personalized patient risk prediction, e-commerce search and fraud detection, outbreak detection in hospitals, and so on.

I am also a member of the inter-disciplinary Computational Epidemiology Group , where I primarily investigate problems motivated by public health such as propagation of diseases via contact network, forecasting outbreaks of infectious diseases, and designing optimal surveillance systems.

Prior to joining UIowa, I received my PhD in Computer Science from Virginia Tech under the supervision of Prof. B. Aditya Prakash. I received my Bachelor’s degree in Computer Engineering from Vistula University in Warsaw, Poland.
