Rongmon Bordoloi

Assistant Professor

Riddick Hall 400L



Dr Rongmon Bordoloi is an observational astrophysicist studying galaxy evolution. He is particularly interested in understanding how galaxies form and evolve, by studying the cycling of baryons into and out of galaxies. He is an expert observer, who routinely uses  multi-wavelength spectroscopy and imaging (both from the ground and space) to study the galaxy baryon cycle. The baryon cycle is vital in regulating  star-formation in galaxies and dictate the evolution of a galaxy. These diffuse reservoirs of gas outside galaxies contain most of the missing baryons in the Universe.  Dr. Bordoloi works closely with theorists who use numerical simulations to study galaxy formation. This close interaction with theorists help in interpreting his own observational results and in constraining different theories of galaxy evolution. He also works on topics related to the formation of the first galaxies, observational cosmology, and the Fermi Bubbles.

Dr Bordoloi joins the Physics Department as an Assistant Professor in 2019. Dr Bordoloi received his PhD from ETH Zurich in 2013. After that he moved to US as a postdoctoral fellow at Space Telescope Science Institute till 2015.  He then moved to Boston to join Massachusetts Institute of Technology as a NASA Hubble Fellow.
