My research work has been featured in Prairie View A&M University's Student Spotlight for my research on analog accelerators for deep neural networks (DNNs).
Last summer 24, I visited Sandia National Labs in Albuquerque, NM, to explore CrossSim, a Python-based crossbar simulator for analog in-memory computing in DNNs. I collaborated with the CrossSim team to integrate it into a Multi-Image Super Resolution (MISR) DNN, testing the effects of cell bits and ADC input profiling.
Received "Outstanding Computer Science Student Award 2025" for academic excellence and contributions.
