About Me

I am a PhD student at the University of Oregon studying pure mathematics. My research interests lie at the intersection of geometry and theoretical physics; in particular I am interested in how algebraic and differential geometry play a role in string theory, and quantum field theory.

Expository Works

The following projects are at various stages of completeness. Please email me with any corrections or questions.

• Algebraic Geometry: Filling in the Gaps This project originally began as my study tool for the Part III algebraic geometry and abelian varieties exams, and was an attempt to fill in the details left as exercises in the lectures. These lectures, by Dhruv Ranganathan and Tony Scholl, were my first introduction to algebraic geometry, and thus the exposition is from the perspective of someone slowly understanding the geometric content in scheme theory. Many comparisons are drawn to the theory of smooth manifolds, as I was at one point much more comfortable with the language of differential geometry than schemes.
  
  These notes have taken on a life of their own since my days at Cambridge, now covering far more than the original lecture series while still omitting much content that I plan to include in the future (in fact, the current draft says nothing of abelian varieties). Since these began as personal notes, I have done a terrible job at citing references; hopefully I will fix this one day. At the moment I have drawn mainly from the aforementioned lectures, the stacks projects, Vakil's 'Rising Sea', Hartshorne, and 'Liu's Algebraic Geometry and Arithmetic Curves'. The topics are presented in an order that makes the most sense to me, though I recognize it may not be the most natural presentation. I am unsure if there will ever be a point where I will say these notes are finished.


• The Geometry of Gauge Theory This is my undergraduate honors thesis which I wrote under the supervision of Matt Szczesny in my final year at Boston University. It was an ambitious project, with the goal of starting at the definition of a smooth manifold, and building up to the construction of the Yang-Mills-Dirac Lagrangian on a pseudo Riemannian manifold. It was heavily inspired by Mark Hamilton's 'Mathematical Gauge Theory', and Lee's 'Smooth Manifolds'. This project is essentially complete; one day I would like to add a chapter on general relativity and gauge theory.

Teaching & Office Hours

My office hours are Mondays from 1:30pm to 3:30pm, and Thursdays from 3pm till 5pm in Fenton 213. In the Spring I will be teaching the following courses:

• MA251. MTWF 10–10:50 AM, Straub 254

Here is my CV.
