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, then 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.
Jeff joined Kitware in April 2006. Jeff is focused on building robust
software tools for informatics and information visualization. He is a
main developer of the Titan informatics toolkit 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 powerful, extensible, scalable visualization framework. He is
currently involved in visualizing data from a variety of sources
including genomics, network traffic, document databases, and
geospatially located information.
