My Erdös number is 4.




I am a currently a sixth year Ph.D. candidate in the Department of Computer Science at the College of William & Mary, under Professor Andreas Stathopoulos. My research interests include numerical linear algebra, iterative methods, preconditioning techniques, trace approximation in lattice QCD, and HPC.
In 2015, I received my Associate's degree in General Studies at Richard Bland College in Petersburg, VA. Following this, I obtained my Bachelor's of Science as a double major in Mathematics and Computer Science in 2018 at Longwood University in Farmville, VA, and my Master's degree in Computer Science with a specialization in Computational Science in 2020 from William & Mary in Williamsburg, VA. I am expected to earn my Ph.D. in Computer Science in the summer of 2024.
