The rank pricing problem: Models and branch-and-cut algorithms
Computers & Operations Research, 2019 One of the main concerns in management and economic planning is to sell the right product to the right customer for the right price. Companies in retail and manufacturing employ pricing strategies to maximize their revenues. The Rank Pricing Problem considers a unit-demand model with unlimited supply and uniform budgets in which customers have a rank ...

Integrability in gravity from Chern-Simons theory
Journal of High Energy PhysicsThis paper presents a new perspective on integrability in theories of gravity. We show how the stationary, axisymmetric sector of General Relativity can be described by the boundary dynamics of a four-dimensional Chern-Simons theory.

Branch-and-Cut Algorithms for Colorful Components Problems
INFORMS Journal on ComputingWe tackle three optimization problems in which a colored graph, where each node is assigned a color, must be partitioned into colorful connected components. A component is defined as colorful if each color appears at most once. The problems differ in the objective function, which determines which partition is the best one.

Branch cuts: writing, editing, and ramified complexities
, 2021 As I was preparing my tenure application, the University of Wisconsin Board of Regents voted to redefine tenure, removing many of the institution's historical protections. Reevaluating my career priorities in light of these changes and a resurgent two-body problem, I recognized that my fundamental goal was communicating mathematical ideas.

Full-potential modeling of blade-vortex interactions [PDF]
A comparison is made of four different models for predicting the unsteady loading induced by a vortex passing close to an airfoil. (1) The first model approximates the vortex effect as a change in the airfoil angle of attack.

On-shell functions on the Coulomb branch of $$\mathcal{N}$$ = 4 SYM
Journal of High Energy PhysicsWe study on-shell functions in the kinematic space for the Coulomb branch of $$\mathcal{N}$$ = 4 SYM. We construct BCFW bridges that help us build bigger on-shell functions.
