Research Assistant Professor
Dr. Kristin Tufte is a Research Assistant Professor in Computer Science and Civil & Environmental Engineering. Dr. Tufte's area of specialization is database systems. In particular, she studies techniques for processing data streams such as network (Internet) traffic, environmental sensor readings, traffic sensor data, and telephone call records. Interesting challenges presented by these types of data are the "unending" nature of data streams and disordered, dirty, skewed, and bursty data. Dr. Tufte is interested in applying data stream technology to Intelligent Transportation Systems (ITS) data streams such as loop detector data and bus dispatch data in an effort to provide improved traffic measurements to ITS professionals. Dr. Tufte is currently involved in the PORTAL project which is archiving ITS data for the purpose of improved traffic assesment and modeling. In her previous research, Dr. Tufte has been involved in the development of two large database systems: most recently, the Niagara Stream Query Engine and previously the Paradise GIS Database.
