Courses I’m teaching this semester (Fall 2018)
STEM For All 2019
This summer I am helping organizing and teaching a mini-course in the Stem For All summer program at U of R. If you are a college student in the Rochester area interested in learning some math and possibly doing some research this summer, you should consider applying! We are especially and actively seeking to recruit students from groups that are underrepresented in STEM
I co-organize the topology seminar. Talks are in Hylan 1106A, 5-6 on Wednesdays. There is also a pretalk, also in Hylan 1106A, 12:45-1:45. Here is our schedule–you may have to scroll down a bit.
I study algebraic topology. I am particularly interested in computations related to equivariant and chromatic homotopy theory, as well as applications to geometric problems (such as the immersion problem for projective spaces and computing cobordism rings). I’ve also recently developed an interest in link invariants related to various link homology theories. Scroll down the page for my publications and preprints.
What I’m currently working on:
I am working with Apurv Nakade on lifting Khovanov and Rozansky’s triply graded link homology (which categorifies the HOMFLY-PT polynomial) to homotopy theory.
Together with Nitu Kitchloo and W. Stephen Wilson I’ve made a bunch of computations with Real Johnson-Wilson theories (certain cohomology theorists that come up in chromatic equivariant homotopy theory). Together with Guchuan Li and J.D. Quigley, I’m working on using them to compute some Mahowald invariants. I’m also interested in finding a way to use unstable ER(n)-operations (which one can say a lot about) to say something about the immersion problem for projective spaces.
Together with Alex Iosevich, Jonathan Passant, and a group of very bright undergraduates, we are thinking about a generalization of the Erdos distinct distance problem in combinatorial geometry. This is a continuation of an REU that Alex and I ran last summer.

Last summer, Alex Iosevich and I ran an REU in combinatorial geometry. It has continued into the year as an independent study.
