Brett WalkerElectro-Mechanical Control Systems Engineer
I work at the intersection of power electronics, controls, and commercial-duty electrification, currently at Allison Transmission, with a growing focus on the business side of emerging vehicle technology.
Engineering background, business direction.
I bring 7+ years of experience spanning Corporate Business and Engineering, across Passenger Automotive, Defense, and Commercial/Hybrid markets. I’m currently an Electro-Mechanical Control Systems Engineer at Allison Transmission, where I lead electromagnetic compliance and controls work on electrified powertrain programs, including the eGen Force and eGen Flex platforms. Before that, I worked in procurement and electronics engineering at North American Lighting, and as a research engineer at Purdue University on EV charging optimization for the IndyGo bus fleet.
I hold a B.S. in Computer Engineering Technology and an M.S. in Electrical and Computer Engineering, and I’m currently completing an MBA. In 2026, I was named a Conexus Rising 30 honoree for my work building Allison’s in-house EMC pre-compliance lab.
The regulatory side of electrified powertrains.
My work on Allison’s TCM and shift-selector electronics runs through electromagnetic compatibility (EMC) testing and certification, the discipline that governs how electronics can coexist with the radio-frequency environment around them. The reference charts below aren’t my own work, credited to their original sources, but they frame the concepts my compliance work is built on.

Two projects, two sides of the same interest.
One is a hands-on power electronics build. The other is a market and investment analysis. Both come from the same question: how does a piece of technology actually earn its place in a vehicle or a portfolio.
Automotive Grid-Connected Inverter Design
A three-phase, two-level inverter for grid-connected vehicle applications, built around power factor, EMI, and THD targets, modeled and simulated in MATLAB/Simulink.
