Biography: I completed B.Sc. (Honours) Physics from Sri Venkateswara College in 2007. After that I did M.Sc. Physics from St.Stephens College in 2009. Post that, I did B.Ed. from Central Institute of Education in 2010. I cleared CSIR NET JRF in Physics in 2009 and completed Ph.D. in Physics (Astrophysics) from Department of Physics and Astrophysics, University of Delhi in 2015. I have 8 years of Postdoctoral Research experience, focused on Astronomical data analysis, from institutes in India and abroad. This includes Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune (from 2015-2018); Kavli Institute for Astronomy and Astrophysics (KIAA), Peking University, Beijing (from 2018-2020); Raman Research Institute (RRI), Bengaluru (from 2020-2023). Since 2024, I am working as an Assistant Professor in Physics at Jaypee University Anoopshahr.

Expertise: Astrophysics, General Theory of Relativity, Cosmology
