About
I am a second-year PhD student in Computer Science at Texas State University, advised by Dr. Martin Burtscher.
I received my BS in Computer Science with a Minor in Mathematics at Texas State University in May 2023.
I research in Dr. Burtscher's Efficient Computing Laboratory (ECL), analyzing and optimizing irregular parallel algorithms.
Research
Converted irregular parallel algorithms to the C++ std::thread standard [Indigo2]
Implemented Minimum Spanning Tree in parallel using CUDA, OpenMP, and C++ std::threads [Indigo3]
Inserted optional parallelism and implementation bugs into CPU/GPU graph analytics codes [Indigo3]
Analyzed performance impact of correcting benign data races in GPU graph analytics codes [ECL-Suite]
