A selective snapshot of some of the most important work that I am currently working on or have worked on. If you’re working on similar problems, feel free to reach out. I’m always happy to compare notes.

GPU Accelerated RAN Algorithm

2025–Present

When we realized that 6G SLS would take ~ 100x longer because of massive antenna arrays, wider bandwidths, and the lack of ISAC abstractions, my team and I turned to scalable GPU computing to bring turnaround times back down to under 6 hours.
