Larry L. Howell is a professor at Brigham Young University where his research focuses on compliant mechanisms including origami-inspired mechanisms, microelectromechanical systems, medical devices, space mechanisms, and developable mechanisms. Howell has also conducted research in lamina emergent mechanisms and nanoinjection.[1] He received a B.S. degree in mechanical engineering from Brigham Young University and M.S. and Ph.D. degrees from Purdue University. His Ph.D. advisor was Ashok Midha, who is regarded as the "Father of Compliant Mechanisms." [2]

Biography[edit]

Howell joined the Brigham Young University faculty in 1994 and served as chair of the Department of Mechanical Engineering from 2001 to 2007 and as Associate Dean of the Ira A. Fulton College of Engineering from 2016.[3] Prior to joining BYU, he was a Visiting Professor at Purdue University, a Finite-Element Analyst for Engineering Methods, Inc., and he was an engineer on the design of the YF-22, the first prototype of the U.S. Air Force F-22 Raptor. His patents, technical publications, and research focus on compliant mechanisms, including origami-inspired mechanisms, space mechanisms, microelectromechanical systems, and medical devices. His research has been funded by the National Science Foundation, Air Force Office of Scientific Research, NASA, Department of Defense, and industry. He is the author of the book Compliant Mechanisms[4] and co-editor of the Handbook of Compliant Mechanisms, which are available in English and Chinese. His lab's work has also been featured in popular venues such as the PBS documentary program NOVA.

Howell is a Fellow of the American Society of Mechanical Engineers (ASME), the Past Chair of the ASME Mechanisms and Robotics Committee, and a past Associate Editor for the Journal of Mechanical Design. His research has been recognized by the National Science Foundation CAREER Award,[5] the Theodore von Kármán Fellowship, and the ASME Mechanisms and Robotics Award, the 2015 "Vizzies" Overall People's Choice Award,[6] the ASME Machine Design Award,[7] and the Purdue University Outstanding Mechanical Engineer (alumni award) among others.

Howell is originally from Portage, a small city in northern Utah with a 2010 census population of 245 people. As a young man, he served as an LDS missionary in Finland.
