## Project Details

### Description

One clue towards a more comprehensive understanding of string theory is the fact that different corners of string theory are often related by "duality": two quite dissimilar seeming physical regimes turn out in fact to be equivalent, or "dual". Duality is ubiquitous in string theory, and may be thought of as a consequence of the fact that a fundamental string has a length and can wrap or wind. This

means that a string sees the world in a fundamentally different way to a particle, demonstrating that a theory of fundamental strings may ultimately display striking differences to our naive expectations.

In this project, I will study new applications of an approach to string theory based on a geometry that captures the effects of dualities. I will use this new geometry to describe string theory scenarios applicable to the physics of our observable universe; develop the fundamental description of the elementary objects of the theory in a unifying language; and understand intriguing connections to a spectrum of seemingly unrelated aspects of physics.
