Hardware / biosensing / controls
Electrical engineer building hardware-centered systems for biosensing, lab automation, embedded navigation, and state estimation.
I work on systems where circuits, fixtures, firmware, and test data all have to agree. That means the work moves between boards, chips, gaskets, sensors, code, and the awkward bench details that decide whether a tool is useful.
Much of my work sits near the physical layer: microfabricated biosensor chips, 555-timer signal-delivery boards, multiplexed electrochemical interfaces, IMU-based navigation, and the validation tools needed to know whether the system is trustworthy.
Selected systems across biosensing hardware, embedded navigation, lab automation, and validation work.
A GPS-free wearable navigation system for recording and retracing a walked path using a foot-mounted IMU, ESP32 hardware, ESKF-based estimation, computer-vision validation, and offline optimizer tooling.
Open project → A compact 555-timer signal-delivery module that reduced a manual biosensor deposition bottleneck and was deployed in Grenada field testing.
Open project →
An active electrochemical signal-routing subsystem for adding deposition and sensing capability to Terry/ASATS, a lower-cost IsoPure-style magnetic bead processing platform.
Open project →
Microfabricated Ti/Au biosensor chips, cleanroom fabrication, lab automation hardware, signal-delivery electronics, optical inspection, and diagnostic workflow support in Yanik Lab at UC Santa Cruz.
Open project →Where project work turns into explanation, field notes, and arguments about why the small engineering choices matter.
Why raw IMU integration fails, why foot-mounted sensing helps, what ZUPT and ZARU correct, and how TARAF is being validated with side-profile computer vision.
