Curriculum Vitae:

Liton Majumdar

I'm an astrophysicist and astrochemist. I am interested in studying chemistry of simple and complex organic molecules in space from interstellar clouds, the birth places of stars, through to protoplanetary disks. These organics eventually seed planetary surfaces and atmospheres and play a role in the "Origin of Life". I use numerical models and single dish telescope observations along with high-spatial and high spectral resolution observations from the ALMA and NOEMA interferometers for my research.
