Dr. Sumit Sarkar is Professor of Information Systems and holds the Charles and Nancy Davidson Chair. "Sarkar's expertise lies in modeling uncertainty in databases and knowledge bases, and devising efficient ways to automate reasoning under uncertain conditions. His fascination with uncertainty modeling has led to publications in a wide variety of applications. For example, his research on personalization demonstrates how a website can quickly infer profiles of customers based on their browsing history, which can in turn be used to improve recommendations in e-commerce environments."
