Scientist and Sysadmin thriving at the intersection of mathematical models, high-performance computing, and data storage.Specializing in Linux clusters and solid-state microstructure evolution in metals. Passionate about building a better tomorrow.

• 🏳️‍⚧️ My pronouns are they/them/theirs.
• 🔭 I’m looking for remote-friendly opportunities in research software engineering and Linux systems administration.
• 🌱 I'm learning about PETSc and spectral methods for PDEs.
• 🪨 I'm easily distracted by cool rocks. Every rock is a cool rock.
• 💬 Ask me aboutgit, high-performance computing (HPC), grain growth in metals, really anything of a technical nature!
• 📫 Drop me a line!tkellerphd@gmail.com

Looking for my contributions on GitHub? Here are a few!

• HPC Carpentry: training materials for novice cluster users.
  • Running Jobs on a Cluster
  • HPC Workflows
• HiPerC: apples-to-apples CUDA and OpenACC comparison for diffusion problems.
• floating-point: exploration of how IEEE-754 represents numbers and why it matters.

• Kim-Kim-Suzuki for phase-field binary solidification:save iterations using a lookup table to solve a routine solidification problem.
• Phase-field Precipitate Aging:incomplete model with explicit finite differencing, which can't reconcile the different timescales required.
• MMSP:explicit finite differencing framework for highly parallel execution.

• Doctoral thesis:Bias in Polycrystal Topology Caused by Grain Boundary Motion by Mean Curvature
• Master's thesis:Effects of Magnesium(II) on Zinc Oxide Nanorod Growth From Aqueous Solution
