I worked as a Research Assistant, implementing and solving complex differential equations in C using the PETSc library. Utilizing Krylov Methods and parallel processing, I was able to quickly and efficiently solve large problems. With this code, I modeled heat systems, visualized them in MATLAB, and analyzed the results in a research paper.
