Researcher (Grant-Funded)
Madison, WIWisconsin Power Systems Group (Prof. Bernard Lesieutre)
Partnered with the federal agency operating the Pacific Northwest power grid to build a MATLAB signal-processing pipeline over a proprietary 1.8 TB dataset and characterize periodic sub-Hz power oscillations driven by GPU-intensive machine learning workloads.
- Selected as an Alvarado Scholar (faculty-interviewed research cohort) and awarded a competitive ECE SPARK fellowship ($7,000) for full-time summer research.
- Partnered with the federal agency operating the Pacific Northwest power grid to build a MATLAB signal-processing pipeline over a proprietary 1.8 TB dataset, resolving data center load behavior at 2 kHz across five months.
- Characterized periodic sub-Hz power oscillations driven by GPU-intensive machine learning workloads, identifying spectral signatures with the potential to excite inter-area and torsional resonance modes in the transmission grid.
- Developed a frequency-domain algorithm correcting current-transformer phase error in instantaneous three-phase power calculations, eliminating a systematic bias affecting 230,000+ minute-long measurement files.

Cadence Virtuoso · CMOS
ECE 555 · Fall 2026
In progressCMOS Neuron for Human Activity Recognition
- Designing a neuron for a multilayer perceptron that classifies sitting and running from accelerometer and knee-stretch sensor inputs, using a multiply–accumulate datapath and ReLU activation with 2-bit signed inputs and weights.
- Developing modular multiplier, adder, and multiplexer blocks in Cadence Virtuoso. The design workflow covers schematic simulation, DRC/LVS verification, and parasitic extraction to evaluate post-layout delay and area.

MATLAB · Python
3ω Thermal-Conductivity Instrument (ETC Lab)
- Designed a 3ω measurement system to test semiconductor thermal conductivity, applying current at ω to produce Joule heating at 2ω and measuring the resulting voltage response at 3ω.
- Built the 3ω measurement system around thin-film heating elements made in a cleanroom using lithography, electron-beam lithography, and thermal deposition.
