Hello World!

I am a Kavli Postdoctoral Scholar at the Kavli Institute for Theoretical Physics (KITP), University of California Santa Barbara. Currently, I did my PhD at the Center for Scientific Computing and Visualization Research (CSCVR), University of Massachusetts (UMass) Dartmouth. I work on gravitational wave astronomy with Prof. Scott Field, Prof. Gaurav Khanna and Prof. Vijay Varma. I am a member of the recently formed UMass-University of Rhodes Island (URI) Gravity Research Consortium (U2GRC). With my awesome Collaborators, I investigate exciting issues in GW sciences. My expertise lies in building reduced order surrogate models for GWs from binary black hole mergers and employing them in data analysis. I am always happy to talk about my works and discuss possible collaborations. Please write to me if you are interested.

Academic Geodesics

  • I passed Secondary School Examination and Higher-Secondary School Examination with 9th and 14th rank out of 1 million and 0.7 million students respectively. I was awarded Haji Md Mohsin Endowment Fund Scholarship from the West Bengal Minorities' Development and Finance Corporation (WBMDFC) of the Govt. of West Bengal, India.

  • I pursued integrated BS-MS in Physics from Indian Institute of Science Education and Research (IISER) Kolkata. I had been an INSPIRE Scholar [supported by the Department of Science and Technology (DST), Govt. of India; from 2013-2018] throughout my undergraduate. My MS Thesis work with Prof. Koushik Dutta and Prof. Rajesh Kumble Nayak focused on testing astrophysical viability of gravitational theories beyond general relativity. I graduated in 2018 with the Best MS Thesis (Physics) award (out of 43 students).

  • Prior to joining PhD at UMass, I was a student at the International Center for Theoretical Sciences (ICTS), Tata Institute of Fundamental Research (TIFR) at Bengaluru, India. I worked with Prof. Parameswaran Ajith on testing the nature of binaries using gravitational waves.

  • During my undergrad, I did internship at the following institutes in India and Europe:

2017-18 Saha Institute of Nuclear Physics, India
2017 May-July Laboratoire d'Astrophysique de Marseille, France
2016 May-July Raman Research Institute, India
2015 May-July Indian Institute of Technology (IIT) Bombay
2014 May-July Indian Institute of Science Education and Research (IISER) Mohali


I am a member of the LIGO-Virgo collaboration, LISA Consortium and Simulating Extreme Spacetimes (SXS) collaboration. For details of my research works, please navigate the following tabs. My research focuses on many aspects of Gravitational-Wave astronomy and beyond GR theories. I work primarily on building reduced order surrogate models from binary black holes based on Numerical Relativity data and point-particle black-hole perturbation theory (ppBHPT) waveforms.
