Ranja Roy received her Ph.D. from Binghamton University in 1998 under the guidance of Distinguished Professor F.T. Farrell, known for his research on Borel Conjecture in Mathematics. Her thesis work resulted in a globally recognized publication, providing a counterexample to a famous Trace Conjecture in the K theory of C*Algebra that was presented in major American and Canadian math society conferences in year 2000. Roy held visiting assistant professor positions at Millersville University and Union College before joining NYIT.

Roy's research interests include algebraic and differential topology and geometric group theory. Currently, her collaborative research with professors at the University of Seville in Spain already has resulted in numerous published research articles.

She has applied her skills in other ways as well. Roy contributed statistical analysis to a study by NYIT's Department of Life Sciences that investigated the link between dietary intake and geographic distribution of liver and stomach cancer in Thailand (research published in the journal Nutrition and Cancer). Roy also enjoys working with students on math modeling projects in science and engineering.
