My research centers on theoretical high energy physics. The broad questions my work aims to address are:
What is quantum field theory, and what are its limitations as a tool in describing Nature?
What are the building blocks of matter and spacetime?
String theory provides a promising way to address these issues since it is the only known viable approach to unifying quantum theory with gravity.
Currently, my efforts are concentrated in three directions:
1) The study of quantum field theory using the extra dimensions of string theory.
2) The study of formal and phenomenological aspects of string compactification, and in particular F-theory.
3) Conceptual questions connected with the embedding of field theoretic UV cutoffs in string theory.
