In my journey as a theoretical physicist, the interconnectivity of seemingly unrelated aspects of Nature's working, and how simple, yet powerful ideas thread it together has always fascinated me. I am interested in studying foundational questions in quantum mechanics and its broader impact in cosmology, gravity, and their signatures in experiment.
Quantum mechanics, gravity, and cosmology have emerged as three key pillars of our fundamental understanding of the universe, and have been tremendously successful in making quantitative predictions for experiments in their respective domains. We anticipate an elegant unification of the microscopic quantum laws with those of gravity and cosmology that govern physics at the largest scales in our universe. However, quantum mechanics and gravity find themselves at strong odds in their current formulation, both conceptually and mathematically, and how they connect with underlying reality. Part of the disconnect can be attributed to the fact that we tend to think in terms of classical ideas such as "space," "particles" and "fields". Such constructions may not have a place in the fundamental ontology of quantum mechanics, which at its heart, simply describes the evolution of a state vector in an abstract Hilbert space. We typically start with some classical theory and then "quantize" it. Presumably Nature works the other way around: it is quantum-mechanical from the start, and a classical limit emerges in the right circumstances.
That should answer your question why this website is called what is it called.
My work falls into three broad categories all hinged on quantum mechanics and quantum information, with an eye towards understanding their role in fundamental questions in gravity and cosmology: (i.) the role of quantum mechanics in the cosmological evolution of the universe, particularly early universe physics, (ii.) emergence of structure in quantum theory with an eye towards quantum gravity, and (iii.) tests of fundamental physics based on ideas at the intersection of quantum information and gravity.
On a slightly tangential note, I am also interested in looking at connections between physics, statistics, and engineering. One such direction I have worked on is the application of Information Field Theory, in particular perturbative field theory techniques (basically Feynman diagrams) to Civil Engineering.
Let me walk you through each of these directions in brief. Do expand on each sub-topic to know more:
