I am currently a Postdoc at SISSA (website), where I work on theoretical aspects of cosmology. In particular, my work is centred around primordial magnetic fields and early universe (pre-BBN) cosmology.
Academic history
I earned my Bachelor’s degree in Mechanical Engineering from IIT Bombay in August 2016. However, by the end of my undergraduate I became quite sure about my interest in physics. Subsequently, I went on to pursue a 1 year Master’s degree in theoretical physics (they have a fancy name: ‘Quantum Fields and Fundamental Forces’) at Imperial College London in 2017. After my masters, I landed in Illinois, pursuing my PhD under Prof. Jessie Shelton and Prof. Peter Adshead. Continuing my streak of continental jumps, I have now came to Italy for my first postdoc.
