Bio

I am responsible for all operations and mechanical design at H3X. In prior roles, I have led projects developing control systems for electric and hybrid powertrain systems from the ground up. I have a BS in Mechanical Engineering from University of Wisconsin-Madison. I come from a proud heritage of craftsmen – from butchers and bakers to electricians and steamfitters. This unique background has enabled me to bridge the gap between advanced engineering theory to practical and scalable solutions.
