Manibrata Sen

I am an Assistant Professor at the Indian Institute of Technology Bombay, India. My current area of research focuses on particle and astroparticle physics.

Previously, I was a research fellow at the Max-Planck-Institut für Kernphysik, Heidelberg, working with Prof. Manfred Lindner. Before that, I was a postdoc with the Network for Neutrinos, Nuclear Astrophysics and Symmetries (N3AS) Physics Frontier Center, UC Berkeley, I was based at Northwestern University with Prof. Andre de Gouvea as my local mentor (2018-2021).

I received my doctorate in theoretical particle physics (2018) from the Tata Institute of Fundamental Research, Mumbai, India, where I worked with Prof. Amol Dighe and Prof. Basudeb Dasgupta.

Research Interests

My research focuses on topics in neutrino physics, and dark matter physics, especially in the context of the early Universe, as well as compact astrophysical objects, like core-collapse supernovae and binary neutron star mergers.

Trained as a neutrino theorist, I combine inputs from astrophysics and cosmology to probe some of the most fundamental questions in our Universe. I have worked on the flavor evolution of dense neutrino streams in astrophysical environments, particularly a core-collapse supernova.

For instance, my recent interests include studying fast flavor conversions of neutrinos emitted from a supernova, as well as binary neutron star mergers.

I am also interested in more fundamental questions governing neutrinos.
