Software

  • JuliaOpt - a suite of optimization software in Julia. Includes:
    • JuMP: an algebraic modeling language for linear, integer, and nonlinear optimization.
    • Convex.jl: a "disciplined convex programming" modeling language.
    • Efficient wrappers for over a dozen state-of-the-art solvers (Gurobi, Ipopt, Mosek, etc.), with a unified, abstract interface.

Research Interests

I study operations research, specifically the theory and application of optimization. Much of my current work is concerned with mathematical formulations: that is, how to translate a high-level optimization problem to a mathematical description we can solve efficiently.

I'm also interested in all aspects of computational optimization, especially user-facing tools for modeling and for developing advanced algorithms.

About Me

I'm a PhD student in the Operations Research Center at MIT, advised by Juan Pablo Vielma. I'm supported by the NSF Graduate Fellowship. I received my B.A. in Applied Mathematics from Rice University, where I worked with Beatrice Riviere and Hadley Wickham.
