FPGA, wireless sensing, and real-time signal processing.

I am a graduate researcher currently building custom low level systems including: an FPGA impedance analyzer that sorts single biological cells in under 5 ms, and a NASA-funded FMCW radar on an RFSoC. I recently graduated from the University of Virginia in 2026 with a B.S. in Electrical Engineering and with Highest Distinction.

Multi-Frequency Impedance Analyzer with Real-Time Biological Cell Sorting

A digital lock-in amplifier and deterministic triggering instrument on a Zynq-7020 SoC with a custom 10-layer mixed-signal board. It excites a microfluidic channel with four tones, demodulates magnitude and phase per frequency in fabric, and fires a sorting actuator at a pre-computed timestamp. Two-person capstone continued as funded research; publication targeted mid-2027.
