Anshuman Acharya | Astrophysics

HELLO!

I'm Anshuman Acharya, a PhD student at the Max Planck Institute for Astrophysics, Garching, Germany (2021-24). Here I am working with Dr. Benedetta Ciardi's group and the LOFAR Epoch of Reionization (EoR) team on improving EoR 21-cm signal simulations to assist extraction and analysis from data collected by telescopes like LOFAR and SKA.

Prior to this, I completed my Bachelor's and Master's at IISER - Mohali, India, with a major in Physics and a minor in Astronomy.
