Primal Pappachan is an Assistant Professor at Portland State University in the Department of Computer Science. I completed my Ph.D. from the Department of Computer Science at the University of California, Irvine. I lead the DIPr (Data & Internet Privacy) Lab. His research interests are in the intersection of data management and privacy. Specifically, my research focuses on data protection methods such as access control, differential privacy, inference control, and privacy policies. My overall research objective is to build data management systems that support fast, scalable, transparent, secure, and private computing.
