Tim McLain

Tim McLain has taught in the Mechanical Engineering Department at Brigham Young University since 1995. After completing his MS degree at BYU, he worked for two years with Sarcos, Inc. in Salt Lake City on the design, modeling, and control of fluid-power systems for robotics applications. While completing his PhD work at Stanford University, Professor McLain worked with the Monterey Bay Aquarium Research Institute on the control of underwater robotic vehicles. Since joining BYU, he has been actively involved in the control of hydraulic actuation systems and microelectro-mechanical systems (MEMS). During the summers of 1999 and 2000, he was a visiting scientist at the Air Force Research Laboratory where he initiated research in the cooperative control of unmanned aircraft systems (UAS). Currently, he is the director of the NSF-sponsored Center for Unmanned Aircraft Systems (C-UAS), which in partnership with the University of Colorado and Virginia Tech, perform industry-sponsored research related to UAS.

Prof. McLain's research efforts are directed towards improving the capabilities of small unmanned air vehicles (UAVs). He collaborates with Prof. Randy Beard of the Electrical and Computer Engineering Department in BYU's Magicc Lab. Together, they involve about 20 students in their research. Information on the research of the Magicc Lab can be found at the Magicc Lab website. The Magicc Lab has received support from numerous agencies including AFOSR, AFRL, NASA, NSF and DARPA.

From 2004 to 2008, Prof. McLain served as the director of the Unmanned Air Vehicle Center of Excellence sponsored by the State of Utah. The objective of the center was to move UAV technology developed at BYU towards commercialization with Utah companies. In connection with the center, two spin-off companies were formed: Procerus Technologies and Flying Sensors.

Currently, Prof. McLain is the director of the NSF-sponsored Center for Unmanned Aircraft Systems (C-UAS). In this center, BYU researchers, in conjunction with researchers at the University of Colorado and Virginia Tech, work with industry sponsors to expand the capabilities and improve the reliability of unmanned aircraft.
