I am primarily interested in black holes and their highly energetic neighborhoods. I study them using x-rays and gravitational waves. Check out Research Interests for details.
My secondary interests include science outreach, linguistics, history and philosophy.
My hobbies include exploring new places, new culture and new food.
2010 BSc in Physics (CMI, India)
2012 MS in Physics (UT Brownsville, Texas, US)
2015 PhD in Physics (UT San Antonio, Texas, US)
2015 Postdoc, Fudan University (Shanghai)
2017 Young Researcher (Tuebingen, Germany)
2019 Humboldt fellow, (Tuebingen, Germany)
With Prof. Bambi's group at Shanghai, I have developed RELXILL_NK (click through to access the model), a model for data analysis of X-rays to look for signatures of modified black holes. Click here for more.
With masters student Lorenzo Kuchler at Tuebingen, I have developed a new generic metric which serves as a theory-independent test of the nature of black holes.
With graduate student Alejandro Cardenas-Avendano at Montana State University, I am working on similar tests of black hole metrics using gravitational waves.
With Dr Victoria Grinberg in Tuebingen, I am investigating how systematic effects, for example interstellar gas, would affect the capabilities of X-ray instruments in testing gravity.
A crucial assumption of RELXILL_NK is the assumption that the accretion disk is infinitesimally thin and located on the equatorial plane. With graduate student Shafqat Riaz in Shanghai, I have studying the changes introduced by a thick disk.
