Biography

Dr. Parimita Roy has served as an Assistant Professor since 2016. An applied mathematician, she specializes in mathematical biology, with research interests that encompass nonlinear population dynamics and complex ecological systems. Her work particularly focuses on extinction risk analysis for endangered species and the mathematical modeling of brain disorders. Dr. Roy earned her Master’s degree in Mathematics and Scientific Computing (MSc) from MNNIT, Allahabad in 2011, followed by a PhD in Applied Mathematics from IIT (ISM), Dhanbad in 2016. She participated in the 5th Heidelberg Laureate Forum from September 23 to 29, 2017, in Heidelberg, Germany, an event that invites only the top 200 young researchers to engage in its unique atmosphere. She has published 22 papers in prestigious SCI/SCIE journals, including ten in Q1 journals. Her current Google Scholar citations total 334, with an h-index of 11 and an i10-index of 12. Some of her research has garnered international media attention, including coverage in prominent outlets (see: [Science Blogs](https://scilogs.spektrum.de/hlf/draft-6-200-parimita-roy-predicting-extinction-risks-endangered-species/) and [HLF Foundation](https://www.newsroom.hlf-foundation.org/blog/article.html?tx_news_pi1%5Baction%5D=detail&tx_news_pi1%5Bcontroller%5D=News&tx_news_pi1%5Bnews%5D=188&cHash=6366942547f0f920e21c6d5fe6596817)). Currently, her research at the University of Leicester focuses on the conservation of coral reefs projected to vanish by 2050. Dr. Roy has secured two major research projects funded by the Indian government and has supervised four Master’s students and one PhD student, with two PhD students currently under her guidance. Recently, she participated in the Interdisciplinary Research Cluster (IRC) on "Exploring shifts in biogeochemical cycles and mass extinction events through slow-fast dynamical systems," funded by the NSF and organized by the Institute for Mathematical and Statistical Innovation at the University of Chicago.
