I have been working on inflation, early universe cosmology, dark energy, dark matter and different classical and quantum aspects of non-canonical field theories. Currently I am interested in the following questions: What was the origin of the expansion in the universe: a quantum gravity or strongly coupled regime, a bounce or something else? Are there alternatives to inflation? What is the microscopic origin of Black Hole thermodynamics? What is inside a black hole? What are possible UV-completions for a QFT? What is Dark Energy and what is the structure of quantum vacuum in the presence of gravity? I hope I will see answers to some of these questions in the near future. I will be very happy, if some of these deep issues are clarified in my research.
