Biography
BSc Physics from St. Stephen's College, Delhi University (2015); MSc Physics from University of Cologne (2018), under Prof. Claus Kiefer, with a master's thesis on a new model of cosmic inflation. PhD from the University of Trieste (2022), under Prof. Angelo Bassi, on primordial black holes as dark matter, testing models of wavefunction collapse via CMB observations and decoherence within quantum electrodynamics. Currently a postdoc at the University of Trieste, in Prof. Angelo Bassi's group.
