In this dissertation I prove various results that encompass multiple fields. Within higher representation theory, I categorify the Boson-Fermion correspondence, settling a standing conjecture of Cautis and Sussan. I categorify the creation and annihilation operators for Schur functions, known as Ber...

In this dissertation I prove various results that encompass multiple fields. Within higher representation theory, I categorify the Boson-Fermion correspondence, settling a standing conjecture of Cautis and Sussan. I categorify the creation and annihilation operators for Schur functions, known as Bernstein operators. I also expand the diagrammatic calculus of Khovanov's Heisenberg category by constructing new explicit branching isomorphisms. Moreover, I show that certain categorical vertex operators are Fock space idempotents, proving another series of conjectures of Cautis and Sussan. Within algebraic combinatorics in joint work with Sami Assaf, I enhance the known tools for Demazure crystals by constructing a new axiomatic local characterization for these crystals.
