It starts with
a little curiosity.
Turn the dial. Change the signal.
That instinct to experiment?
It’s how I approach engineering.

Think at the edge.
A TinyML model classifies falls on-device. A warning and cancellation window let the wearer respond before an alert is sent.

Automated a photovoltaic testbed with Arduino control, relay-switched power stages, and closed-loop temperature control. Python-driven illumination sweeps logged data at 20 samples per minute.
Inside the testbed +
Integrated DS18B20 sensors, a thermoelectric module, and a programmable power supply. Designed and 3D printed mounting brackets in Fusion 360 to secure the hardware.

Less waiting.
More understanding.
Built Python and MATLAB workflows for Monte Carlo simulations of electron-hole creation in GaAs. Processed over a million rows and reduced analysis time by 85%.
Inside the analysis +
Simulated 13 energy levels from 5 to 65 keV. Built repeatable visualizations and benchmarked simulation output against published GaAs radiation-response data.

I’m Tri Phan, an electrical engineering student at Illinois Institute of Technology.
I work across embedded systems, semiconductor research, and power design. I enjoy turning an uncertain idea into something I can wire up, program, measure, and improve.
