About Me

I am expecting to graduate with a PhD in Applied and Computational Mathematics from Southern Methodist University in May, 2023. My advisor is Daniel Reynolds and I am currently funded by FASTMath SciDAC. My research is focused on adaptivity in multirate numerical IVP-solving methods.

I am passionate about mathematics and software development with experience in industry, academia, and national labs.

I am currently looking for a post-graduation job in computational mathematics, scientific computing, machine learning, and related fields!

Professional Experience

Intern, Lawrence-Livermore National Lab

In the summer of 2022 I interned with the SUNDIALS team to optimize integrator parameters, in collaboration with the GPTune team.

Software Engineer, Northrop Grumman

From May, 2018 to June, 2020, as both intern and full software engineer, I worked with a team in an agile environment to develop software for the US Government.

Intern, InterPublic Group

In the summer of 2017 I interned with InterPublic Group, writing user-management scripts and developing tools for their global IT Support.
