4th year graduate student at Columbia University. My advisor is Eric Urban.
This year, Yihang Zhu and I are organizing a seminar on the work of Harris and Henniart on the proof of the Local Langlands conjectures for GL_n. During this fall semester, the focus will be mainly on the automorphic side of the story. We will save most, if not all, of the geometry for next semester.
Time and place: Tuesdays 4:30-6:00 in Mathematics 507.
Michael Zhao has been Live-TeXing notes for the seminar. They are available on his webpage.

The following three references directly prove the Local Langlands Conjectures, and local-global compatibility at bad primes, by studying certain simple Shimura varieties at those primes. We will not use these references during the first semester, but it is important to know about them.

Right now I am writing a friendly introductory survey of Iwasawa theory, based on lectures I gave at PROMYS in the summer of 2018. They will be available shortly.
Here is my senior thesis (45 pages). The last section contains a new adelic proof of the Riemann-Roch Theorem for number fields.
Here is a link to my paper on this proof on the arXiv (8 pages).
Local Compactness and Number Theory: These are the notes for a seminar course (Math 639 Section 001) which I taught at UNM in the spring of 2015.
