Jessamyn's current mathematical interests are very broad and include algebraic structures, braids, knots, lattice models, and anything that might secretly be yarn.

Most recently they have been working with a particular set of K3 surfaces as part of a project that developed out of Rethinking Number Theory 4; a paper is available on the ArXiv here:  Hypergeometric decomposition of Delsarte K3 pencils 

 In summer 2022 they participated in a Polymath Jr. group and subsequently published a paper on the 6-vertex "ice rule" lattice model in n colors, on the ArXiv here: Solving the n-color ice model
