Dr. Preetom Nag joined North South University as an assistant professor in January 2018. Before his joining, he had an experience as an Assistant Professor (Specially Appointed) in the Molecule & Life Non-linear Sciences Laboratory, Research Center of Mathematics for Social Creativity, RIES, Hokkaido University, Japan. He obtained PhD from the same laboratory in the field of Life Science. For PhD research (2011-2014), he was awarded the "Monbukagakusho (Mext)" scholarship by the Japanese government. His PhD works provided a mathematical pedagogy to understand the dynamical heterogeneity in a complex fluid system such as colloidal fluids in response to a mechanical perturbation. After PhD, Dr. Nag continued his research as a postdoctoral research fellow in Mathematical & System Sciences for a project to infer the behavior of epithelium cell colonies during their collective migration.

Dr. Nag's research area includes Computational fluid dynamics, Chaotic mixing in complex fluid systems, Lagrangian Coherent Structures (LCSs), Collective behavior of biological systems, Data Science, and Information theory.
