BRIEF BIO

Understanding many-body systems through corroboration with data is in general computation inten- sive. In this regard, the atomic nucleus is one among the best examples. Studying nuclei at the limits of stability leads to a better understanding of the nuclear force which is still elusive. Theoretical efforts in this direction mainly focus on validating, at such extreme limits, the nuclear models and hence the underlying assumptions. We are investigating the properties of atomic nuclei at extreme conditions and the associated phase transitions. These topics are very interesting and have the potential to unrav- el several fundamental aspects of physics of many-body systems. My research interests are Nuclear Structure Theory: Giant resonances, nuclear fission, thermal pairing, nuclear level density.
