Background

I am a research software engineer, applied mathematician, and STEM educator. My experience includes performance portable software development for physics based simulations on exascale hardware as part of centers funded by grants from the Department of Energy and statistical analysis for the U.S. Air Force. I have professional experience in C, Rust, Python, C++, CUDA, Julia, Fortran, and R, among other languages. I have taught at the U.S. Air Force Academy and University of Colorado at Boulder, and I am a mentor online at freeCodeCamp and help moderate the freeCodeCamp Discord and freeCodeCamp Forums.

Software

libCEED

libCEED logo

libCEED provides fast algebra for element-based discretizations, designed for performance portability, run-time flexibility, and clean embedding in higher level libraries and applications. It offers a C99 interface as well as bindings for Fortran, Python, Julia , and Rust. While our focus is on high-order finite elements, the approach is mostly algebraic and thus applicable to other discretizations in factored form.

Ratel

Ratel logo

Ratel provides solid mechanics solvers based on libCEED and PETSc. While the current library focuses on hyperelastic formulations, with ongoing work in quasistatic and fully dynamic examples, the long term goal of this project is to implement the material point method in a matrix free fashion.

HONEE

HONEE provides fluid dynamics solvers based on libCEED and PETSc. The library solves the compressible Navier-Stokes equations in three dimensions using explicit or implicit time integration.

LFAToolkit.jl

Local Fourier Analysis is a tool commonly used in the analysis of multigrid and multilevel algorithms for solving partial differential equations via finite element or finite difference methods. This analysis can be used to predict convergence rates and optimize parameters in multilevel methods and preconditioners. This package provides a toolkit for analyzing the performance of preconditioners for arbitrary, user provided weak forms of partial differential equations.

A list of my publications can be found on ORCiD, ResearchGate, and Google Scholar. The source and PDFs of my presentations can be found on GitHub.

Hobbies

BattleTech

Colorado BattleTech logo

I enjoy playing BattleTech and run demos as part of the Catalyst Demo Team. It is especially important to me for new players to feel safe and welcome joining this hobby space. See the Colorado BattleTech website to find BattleTech players in Colorado. I also help moderate the Catalyst Game Labs Discord and Colorado BattleTech Discord online communities.

BattleTech Outworlds Wastes logo

I’ve developed a lightweight narrative league and event framework with simplified logistics rules, BattleTech: Outworlds Wastes.

Mercenary's Pride logo

Mercenary’s Pride is a fun project retelling Jane Austin’s Pride and Prejudice as a series of BattleTech scenarios and comm logs.
