91�ؿ�

Brent Hoffmeister joined 91�ؿ� in 1996 and served as Physics Department Chair from  2006 - 2023. He is the faculty advisor of 91�ؿ�’ award-winning chapter of the Society of Physics Students (SPS). In 2011, he received national recognition as an Outstanding SPS Chapter Advisor. He also is a faculty supervisor for the 91�ؿ� CubeSat team that is working with NASA and the University of Oklahoma to develop a satellite to test novel photovoltaic cells in low earth orbit. Dr. Hoffmeister has taught several different physics courses at 91�ؿ�, with topics ranging from the physics of music to advanced electromagnetic theory. Dr. Hoffmeister is the Director of the Physics Laboratory for Ultrasonic Studies (PLUS) at 91�ؿ�, where he collaborates with Dr. Ann Viano to develop ultrasonic techniques to diagnose osteoporosis. In 2021, he was named a Fellow of the Acoustical Society of America for “contributions to the understanding of ultrasound characterization of bone.”
