Still chasing the questions I had as a kid—just getting better at answering them.

Soldering fine wires onto an earpiece electrode assembly at a workbench
Students crowd around a live EEG demo in a chalkboard classroom
Cluttered vintage electronics bench with vacuum tubes and glowing oscilloscopes
Working in a respirator and gloves beside a hot plate stirrer
Wearing an EEG electrode cap in a gym mirror
Prototype ear-worn electrode headset with ribbon cables during fitting
Showing prototype hardware to students at a lecture-hall table
Electron micrograph of a microneedle array at 31x magnification
Foil-covered beakers stirring on a row of hot plates
Thumbs up in a lab coat, respirator, and purple nitrile gloves
Bare green circuit board with playful Doofenshmirtz-themed silkscreen art
Glass electrochemical cell wired to a Gamry potentiostat
Room of resin 3D printers and wash stations
Microscope close-up of coated microneedle tips
Clear 3D-printed hexagonal lattice standing on a wooden desk
Motorized gantry rig positioning a probe over a tissue phantom
Gel-coated electrode array on a flexible circuit, up close
Sawing open a gel skull phantom clamped in a bench vise
Water tank test bench with oscilloscope and submerged phantom
Transcranial focused ultrasound planning software with MRI targeting views
Circle-and-slash symbol burning on a parking lot at night
A goldendoodle sitting on the workshop's polished concrete floor
Two engineers grinning over halves of a cut-open skull phantom
Holding a 3D-printed resin lattice in a gloved hand
