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:
Structure and evolution of biological networks, Structural changes in human brain
functional networks in ageing.
Analysis of nonlinear differential forms, Pullback equations, Differential inclusions,
Nonconvex calculus of variations.
Depth functions in high dimension, Gaussian process, MCMC simulation.
Ordering and ageing of probability distributions, Weighted distributions, Order statistics and
records, Entropy, Replacement and maintenance.
