Matt is an Education Mechanical Engineer at VEX Robotics. Matt recently graduated Magna Cum Laude from Robert Morris University (RMU) with a Bachelor of Science in Engineering and a concentration in Mechanical Engineering. He was introduced to VEX through his work with the VEX V5 Workcell at RMU. Matt brings his expertise and experience as a former math and engineering tutor to his work with VEX, and enjoys finding ways to get students and educators excited about building and engineering. He works to find ways to set students and teachers up for success as they begin building, by sharing his knowledge about why and how builds function in accessible and creative ways.

Matt’s favorite thing about STEM learning is that “there is an endless amount of solutions to any problem. It’s just about finding the optimal solution to the problem, and iterating on your ideas until you do."
