Gravitational Waves from a Quantum Field Theory Perspective

Subhendra Mohanty obtained his PhD from University of Wisconsin, Madison, USA in 1989. After that he held postdoctoral positions at CERN and ICTP. He joined the Physical Research Laboratory in Ahmedabad (India) in 1994, where he is currently a Professor. He spent a sabbatical year in Universita Autonoma of Barcelona in 2007. His fields of investigation are particle physics and cosmology. He was elected as a Fellow of National Academy of Sciences India in 2021.He published 100+ papers in international peer-reviewed journals and has been involved in teaching courses for graduate students and young researchers. He already published in Lecture Notes in Physics the volume Astroparticle Physics and Cosmology: Perspectives in the Multimessenger Era (Springer, 2020).
