Peter McDonald

I'm a sixth year graduate student in mathematics at the University of Utah interested in commutative algebra and algebraic geometry, particularly the use of derived category methods to study singularities in equal characteristic. My advisors are Srikanth Iyengar and Karl Schwede. Check out our student commutative algebra seminar, BIKES.

Before coming to Utah, I had a brief stint in consulting at EY-Parthenon. Prior to that, I received my BA in mathematics from Williams College in Williamstown, MA where I did research in commutative algebra with Susan Loepp and on multidimensional continued fractions with Tom Garrity. Outside of math, I enjoy skiing, hiking, biking, roller skating, and (listening and dancing to) music. I'm also passionate about public transit and urbanism and am a board member of Sweet Streets.

I am on the academic job market this year! Here is a copy of my CV (updated January 2024).

Below are some activities I've been involved with here in the math department.

Association for Women in Mathematics

While I'm not currently involved with the AWM, I've organized two editions of our RTG Conference BRIDGES and was also treasurer for the two years before that. As an organization, we are focused on supporting all underrepresented groups in mathematics. You can find out more information about our activities on our website.

BRIDGES Workshop

Last summer, I chaired the organizing committee for the BRIDGES Workshop, hosted at the University of Utah June 7-10, 2022. Intended for advanced undergraduate and early career graduate students interested in algebraic geometry, commutative algebra, geometric group theory, and number theory, the conference aims to introduce students to possible research areas and build a sense of community among a diverse group of young mathematicians. More information can be found on our website. The next iteration of this conference will be summer 2024!

University of Utah Directed Reading Program in Mathematics

The University of Utah Directed Reading Program in mathematics partners undergraduate students with graduate mentors to pursue independent reading projects during the semester. In the past, I've worked with students to read about algebraic geometry, complex analysis, and mathematical logic. The program is not currently running, but more information about the program can be found here.
