Dr. Austin Lines, a mechanical research engineer and ice friction researcher at the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory (CRREL), slides down a luge track during an ice friction workshop held by USA Luge in Park City, Utah. Austin and Dr. Emily Asenath-Smith, lead of the Ice Adhesion Facility at CRREL, were invited to be a part of an interdisciplinary research and development team to develop approaches that decrease ice friction and increase speed for the luge team.
