Dr. Raja Sengupta is an Associate Professor of Geography at McGill University. Raja’s research projects follow three distinct but complementary paths that fall under the broad umbrella of GIScience: agent-based models (ABMs), spatial tools to measure anthropogenic impacts, and methodological improvements to existing GIScience tools. Within GIScience, the use of ABMs for modeling complex biological and social systems is a new and emerging topic of inquiry. Raja’s goal has been to develop GIS-based analysis and tools that spatially link disturbances with outcomes at the landscape level, with a view to informing policy making. Finally, a third research trajectory of Raja’s focuses on improving existing methods, or creating new algorithms, to solve problems encountered with GIS in its current temporally static, two-dimensional, database-centric form. Raja received his PhD in Geography from Southern Illinois University Carbondale. Raja served as a member on SESYNC’s External Advisory Board.
