Integrated Photonics and Semiconductor Fabrication, a perfect match.

Microrings that resonate
Microring and microdisk resonators for dense wavelength-division multiplexing. I am now working towards designing systems in ANSYS Lumerical to address AI power dissipation bottlenecks.

Measuring films by their color
I built a python program to measure SiO₂ thickness on silicon with an OceanOptics HR2000+. Report in progress.
90.36 nm · RMSE 0.0097 — measured vs. Fresnel fit after dark subtraction
Full-stack monitoring for a fleet of Bambu and Prusa printers, including a subnet auto-discovery script so new machines announce themselves instead of being added by hand.

public circuits-practice site · in use now
An open educational resource for circuit analysis, with assignment attempt-tracking I rebuilt around Firestore transactions after hunting down two interlocking bugs in the deploy pipeline.
A bed-of-nails alternative: probes on a CoreXY motion system measuring impedance point-to-point, so a bare board gets tested without machining a custom fixture for it.

Laser-Doped Diode
laser doping of silicon → p-n junction
Driving dopant into silicon with a laser to form a working junction using close to hobbyist equipment. Success criterion: one honest rectifying IV curve.

Maskless Lithography
DMD projection · Elegoo Mars 4 as UV source
Homemade photolithography: a resin printer repurposed as a UV exposure unit already gave a clean first exposure in dry-film resist. Next up, a UV laser photolithography device built from a gutted MakerBot 3D Printer.

In the classroom
TA, ECE 2001 — and my passion for teaching
I propose repeatable, intuition building practice sets into shifting the way students learn. I also make videos to guide my students when the patches get rough. All this lives free to the public at circuitspractice.org and YouTube.
