Expertise

Theoretical Condensed Matter Physics

Profile

Professor Bulbul Chakraborty is a condensed matter theorist who is interested in systems far from equilibrium. Her recent research has been focused on a) analyzing the origin of glassy dynamics in supercooled liquids with a specific focus on the question of an underlying critical point, (b) exploring the origin of force chains in granular media and their effect on the jamming of granular flows, (c) the nature of the jamming transition and (d) modelling the dynamical instability in microtubules.
