About
I'm a Senior Staff Research Engineer at Samsung Research America, working on wireless systems and DSP for the next generation of radio access. Today I manage the Platform Innovation Team within the Advanced MIMO Lab, where my day-to-day spans upper mid-band (FR3) massive MIMO platforms, advanced duplexing (XDD and sub-band full duplex), and digital predistortion. It's the messy intersection of RF, signal processing, and software where most of the interesting problems live.
I grew up in southwest Louisiana and started at Louisiana Tech, where I stacked a math degree onto electrical engineering because I couldn't quite pick. Senior design was a 250 W HF power amplifier, which in retrospect explains a lot about everything I've done since.
From Louisiana Tech I went to Rice University, first for an M.S. in Electrical & Computer Engineering. That thesis was on low-complexity sub-band digital predistortion for noncontiguous LTE carrier aggregation, a problem that started as a specific 5G spectrum-fragmentation concern and kicked off a multi-year line of conference and journal papers and a small Matlab library researchers still poke at. I stayed at Rice for a Ph.D. under Joseph R. Cavallaro and pivoted to neural networks for the radio. The dissertation, "Nonlinearity Correction in Massive MIMO Systems via Virtual DPD", used a neural network to do predistortion before precoding in a massive array, turning what had been a hardware problem into a software one.
I first joined Samsung Research America as an RF and PoC intern in 2017 and 2019, working on a GPU LDPC decoder for vRAN and LTE spectrum-sharing tools in the CBRS band. I came on full-time in 2020 and have been pushing on the systems side of advanced cellular ever since: sub-band full duplex (XDD), distributed and hybrid MIMO, satellite NR, GPU-based LDPC for vRAN, and an upper mid-band (FR3) 256-TRX massive MIMO PoC that I led the RF development for. In my current role I'm leading the Platform Innovation Team within the Advanced MIMO Lab, focused on GPU-based AI-RAN testbeds and AI-driven DPD for high-efficiency PAs. A lot of the work shows up in the publications list and projects page.
Before Samsung went full-time, I spent a summer at Lockheed Martin doing SDR development with the Cyber Solutions IRAD group, building a real-time wireless sensing application in GNU Radio. It's where I learned how much fun a fast feedback loop between RF, software, and a deadline can be.
Outside work
My wife Jennifer and I are based in Texas. When I'm not staring at a constellation diagram I'm usually hiking, drinking coffee that is probably too strong, or (yes, fine) running on Strava. I also write occasionally about wireless and tooling on the posts page.
