Commutative and Homological Algebra Market Presentations

a virtual seminar series in commutative algebra

The main goal of CHAMPS is to give graduate students and other early career researchers on the academic job market a platform to showcase their research. CHAMPS started as a weekly virtual seminar in Fall 2020, created by Eloísa Grifo and Keri Sather-Wagstaff and based on an idea by Keri and Hugh Geller. In the first two years we had weekly seminars. In Fall 2022 we will profiling early-career researchers on our website and releasing elevator pitch videos on our YouTube channel.

Here are our 2020-2021 speakers and our 2021-2022 speakers.

All past seminars and elevator pitch videos can be found on our YouTube channel.

If would like to recommend an early career researcher in commutative algebra and related fields to speak at CHAMPS, please contact us.

Postgrads on the 2022-2023 academic job market

Josh Pollitz is an NSF postdoc at the University of Utah, working with Srikanth Iyengar. He received his PhD from the University of Nebraska-Lincoln in 2019 under the supervision of Luchezar Avramov and Mark Walker. Josh's research interests are in commutative algebra, especially applying homological techniques to acquire ring and module theoretic data. He has had successes applying triangulated category techniques, certain notions of cohomological support, Hochschild cohomology and certain graded Lie algebras associated to rings or maps. As an educator, Josh has taught a variety of courses at all levels of undergraduate mathematics. He puts an emphasis on group work and creating a dynamic and welcoming learning environment.
