About Me

Utkarsh Mandavilli

I am a junior pursuing a BS & MS degree in Electrical Engineering at the University of Colorado-Boulder, where I continue to develop a wide range of technical and soft skills. I have experience with digital and analog electronics, digital and embedded systems, various coding/scripting languages, manufacturing and circuit design and testing. I work year-round for the NASA Colorado Space Grant Consortium for their project teams as a technical lead where we develop and implement engineering solutions to terrestrial and extra-terrestrial problems. I'm also a dedicated member of the CU Ultimate Frisbee team which competes at the Division 1 Level of college sports.

Lab Projects
