Research
Prof. Debarati Chatterjee is a theoretical astrophysicist with an expertise in analytical and numerical description of compact stars (neutron stars and white dwarfs). Her main interests are in developing global models which take into account both microscopic (involving interdisciplinary physics such as nuclear and particle physics, superconductivity) and macroscopic aspects (magnetic fields, relativity) consistently in order to improve astrophysical simulations and for better interpretation of multi-messenger astrophysical observations.
