Education
BS, Electrical Engineering and Applied Mathematics, Minor in Physics, University of Colorado Boulder, May 2026 (expected).
Technical Skills
I am interested in applied electromagnetic, RF systems, and analog circuit design in general. I have mathematical interest in numerical methods for PDEs and non-linear dynamics.
Skills: Circuit design, simulation (ADS, AWR), electromagnetics simulation (HFSS, FEKO), PCB design (Altium), experience with RF test equipment (VNAs, spectrum analyzers, antenna characterization)
Languages: C/C++, MATLAB, Python, Verilog, Rust, HTML/CSS/JS.
Employment
Research Assistant, Antenna Research Group, CU Boulder May 2024 - Present
- Developed electrically small antennas for HF communication applications, including design of a novel elliptically polarized small antenna.
Research Assistant, High Speed Digital Engineering Group, CU Boulder May 2023 - May 2024
- Investigated techniques for designing high bandwidth interconnects with silver nanoparticle (AgNP) conductive inks.
- Fabricated, measured, and modelled microstrip test structures from AgNP inks, demonstrating feasible interconnects to 10 GHz.
- Developed custom instrumentation (circuit, PCB, and software) for pulsed I-V measurements of ink structures, demonstrating I-V under isothermal and heated conditions.
- Investigated characteristics of Cu–AgNP interfaces and techniques for rapid prototyping of ink circuits onto existing copper structures.
Learning Assistant, Department of Electrical, Computer, and Energy Engineering, CU Boulder Aug 2023 - Dec 2023
- Lectured introductory electronics, helped students design and build freshman engineering projects.
