Jeff earned B.S. degrees in Computer Science and Mathematics from Clarkson University in 2000. Since then, he worked for two years at Eastman Kodak in Rochester, NY as a development engineer, and also participated in their Imaging Science Career Development Program. At Kodak he developed computer models for photographic film scanners and digital microfilm writers. From 2003 until 2006 he was a Ph.D. student at Rensselaer Polytechnic Institute. A student of Prof. Mark Goldberg, his thesis topic was Discovering Groups in Communication Networks. The goal of his research there was to automatically discover coalitions in vast communication databases using structural information only. His contributions include novel graph clustering algorithms which allow cluster overlap, and algorithms for discovering subsets of individuals persistently connected over time. He has also developed a software tool for executing these algorithms and visualizing the results.

Jeff joined Kitware part time in April 2006, and became a full-time employee in September 2006. Jeff is focused on the information visualization project, Titan in conjunction with Sandia National Laboratories.  The purpose of Titan is to add support for visualizing graphs, trees, tables, databases, and the Earth into VTK in a way that integrates with existing scientific visualization capabilities to create a powerful visualization framework.
