who. we. are.
Dr. L is currently in the Mechanical Engineering Department at Colorado School of Mines. She received her B.S. in Aerospace Engineering and B.A. in Dance Performance as a Shipman Scholar from the University of Michigan, and her M.S. degree in Aerospace Engineering from the Georgia Institute of Technology as a NASA Space Grant fellow with a thesis on thin foil fatigue. Leslie received her Ph.D. from the California Institute of Technology under Prof. Ares Rosakis, researching hypervelocity impact damage as a NASA Aeronautics Scholar and NSF Graduate Research Fellow. A former Lockheed Martin Aeronautics Advanced Development Programs (Skunk Works) engineer, Leslie is a recipient of an NSDEG Graduate Research Fellowship, Zonta International Amelia Earhart Fellowship, and the 2009 Ernest E. Sechler Award from Caltech. Leslie spent the summer of 2013 at NASA Glenn as a Faculty Fellow, and she is a 2017 ONR Young Investigator and a 2018 NSF CAREER awardee.
ASSISTANT RESEARCH FACULTY
Research Focus: Low-Impedance Cellular Material Characterization and Development for Next-Generation Helmet Liners to Mitigate TBI
Dr. Koumlis received his B.S. in Aeronautical and Mechanical Engineering from the University of Patras, Greece, with a major in structural mechanics and minor in applied mechanics, materials technology and biomechanics. He received his MSc and PhD in Mechanical Engineering from the University of Southern California in Los Angeles, with a dissertation on an experimental model of blunt-impact induced traumatic brain injuries under Prof. Veronica Eliasson. He also has expertise in shock mechanics and combustion kinetics. Stelios is heading the XSTRM Lab side of a joint ONR project lead by Prof. Christian Franck at U-Wisconsin, Brown University, Sandia National Laboratory and Team Wendy, focusing on dynamic deformation and failure of helmet foam liners for improved head gear and testing methods that address and prevent mild traumatic brain injury (mTBI) and blast related TBI.
