The Department of Mathematics & Statistics at IISER Kolkata has a diverse mix of faculty members actively involved in research. Faculty research interests encompass a wide spectrum of areas. Research groups engaged in core areas of mathematics coexist with groups working in applied mathematics and statistics, to create a synergistic research approach in order to understand problems that lie at the juncture of several disciplines. The collective knowledge helps in providing a perspective to promote the interdisciplinary use of mathematics and statistics across various areas of science and engineering. Some of the thrust areas of research in the department are as follows:
