About Me

This website is a technical portfolio and place for posts from my hobbies.

In 2022, I graduated with MS and BS degrees in mechanical engineering from Drexel University in Phildelphia, PA.

My primary professional interests are precision motion systems, vibrations, damping, flexures, design of linear/rotary electric machines (motors), numerical methods, and precision machining/fabrication.

The work I most enjoy is applying fundamental engineering concepts to high complexity next-generation machines, equipment, etc... in all domains of mechanical and electrical engineering (structural statics/dynamics, heat transfer, electro-magnetism, fluid dynamics, control systems, etc...).

I ride and race XC and Downhill mountain bikes. I like working on them and doing/making things to make them better. Click to see some of my recent race results.
