Andrew Petruska

Assistant Professor, Mechanical Engineering

Andrew PetruskaAndrew Petruska joined the Mechanical Engineering department at Colorado School of Mines in 2016, where he is currently an Assistant Professor.  He graduated from Carnegie Mellon University, Pittsburgh, PA, USA in 2005 with dual B.S. degrees in Mechanical Engineering and Physics as well as an M.S. degree in Mechanical Engineering. For the next four years, he worked as a Design Engineer at ATK Launch Systems in Utah and was responsible for designing, testing, and qualifying solid rocket motor components. In 2010, he enrolled at the University of Utah and was awarded an NSF IGERT Fellowship to study noncontact magnetic manipulation. He received his PhD in 2014 after developing the first real-time reconfigurable magnetic manipulation system. In 2014, he joined the Multiscale Robotics Laboratory in the Institute of Robotics and Intelligent Systems at ETH Zurich and was awarded a Max Planck ETH Center for Learning Systems fellowship, where he investigated the magnetic manipulation of needles, endoscopes, and catheters. His research interests are in the areas of complex system modeling and design, dynamics and control, and advanced magnetic manipulation.
