Raja Sengupta's research projects follow three distinct but complementary paths that fall under the broad umbrella of GIScience: agent-based models, spatial tools to measure anthropogenic impacts, and methodological improvements to existing GIScience tools. Within GIScience, the use of agent-based models (ABMs) for modelling complex biological and social systems is a new and emerging topic of enquiry. Further, the use of GIS and modeling to understand the impact of anthropogenic disturbance on ecosystems, and thereby direct policy, is an emerging area of enquiry. Within this broad area of research, Sengupta'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 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.
