Work

Researcher, designer, and builder working across AI/ML, defense systems, and creative technology. PhD in High-Frequency Devices from University of Arkansas. Previously led Xtremis AI's 600-acre spectrum research campus and $80M Army contracts.

Director of Experimentation | Deputy Principal Investigator — Xtremis AI
2023–2025 | Established and operationalized a 600-acre isolated RF research facility — architecting networking infrastructure, deploying servers and computing resources, and staffing a multidisciplinary team of 8. Deployed to Middle Eastern warzones to integrate RF localization systems with Special Operations Task Forces. Led ML-driven signal identification, AoA/TDoA localization, and noise filtering for field-ready capabilities.
Research Lead — KCNSC, Honeywell FM&T Radar Consortium
2019–2023 | Patented novel assembly methods for W-Band power amplifiers. Led design, simulation, fabrication, and characterization of K-Band and W-Band radar systems using LTCC packaging.
Doctoral Academy Fellow — University of Arkansas
2018–2023 | Developed computational models for high-frequency semiconductor devices with deep learning-based surrogate models. Theorized and designed patented Double Gunn Diode semiconductor devices.
Systems Engineering — Northrop Grumman
2017–2018 | Automated EMIT cosite analysis. Completed EMI/EMC compliance for NATO program aircraft per DO-160D and MIL-STD-461.
