Research interests

My research is driven by the search for a unified theory of quantum gravity that combines gravity with quantum mechanics. The aim is to understand the workings of gravity at small distance scales when quantum mechanics cannot be ignored. Examples of such extreme conditions are the Big Bang at the start of our universe and the black holes predicted by Einstein's theory of gravity.  My present work is focused on  non-relativistic string theory and its underlying non-relativistic gravity and geometry  to find out whether or not relativity is indispensable for the construction of a theory of quantum gravity. A popular introduction  to this issue can be found at the website

I am using the same non-relativistic geometry in effective field theory to gain new insights into certain aspects of the fractional quantum Hall effect.
