As a teen, Borchelt was always interested in complex puzzles, which helped her decision to being an engineer. “Being an engineer is really just the grown up version of playing with puzzles all day. It's our job to find the best way to put things together in order to achieve a defined goal. We observe the world as it is and use our knowledge to create the next iteration.” Borchelt attended Indiana University Purdue University Indianapolis (IUPUI) where she earned a Bachelor’s of Science Motorsports Engineering degree. From there she worked with Vance and Hines Motorsports as a Design Engineer Intern from 2010 through 2011 and from 2011 through 2012 with Hendrick Motorsports as a Design Engineer Intern before joining Team Penske.
