Expanding the frontiers of physics and acoustics, Micah Shepherd serves as an Associate Professor within the Department of Physics and Astronomy at Brigham Young University. His academic path began at BYU, where he cultivated a strong foundation, earning his Bachelor of Science in Applied Physics in 2005, followed by a Master of Science in Physics just two years later. This early dedication set the stage for his continued scholarly pursuits.
His journey then led him to Penn State, a renowned center for acoustics research. There, he contributed significantly as a research faculty member, deepening his expertise and ultimately achieving his PhD in Acoustics in 2014. This period was crucial in shaping his specialized knowledge and research focus, building upon the broad physics background he gained at BYU.
Professor Shepherd's research interests span a fascinating range of topics, reflecting a deep curiosity about the physical world and its sonic manifestations. He has delved into the complexities of thermoelasticity, exploring how temperature changes affect material properties, and has also contributed to understanding the intense sound environments associated with launch vehicles. His work extends to vibration-based sound power, investigating how mechanical vibrations translate into audible sound.
A particularly engaging area of his research involves the intricate physics behind percussion instruments. He seeks to uncover the fundamental principles that govern how these instruments produce their unique sounds and resonate, blending his physics expertise with an appreciation for musical acoustics. Additionally, he is involved in the vital field of signal characterization of seizures, a research area with significant implications for advancing medical diagnostics and potentially improving treatment approaches.
Since returning to BYU in 2022 to join the faculty, Professor Shepherd has been dedicated to cultivating a vibrant and collaborative research atmosphere. He is passionate about integrating his cutting-edge research directly into his teaching, providing students with firsthand exposure to the exciting developments at the forefront of physics and acoustics and inspiring them to explore these fields further.
Beyond his research and teaching, Professor Shepherd is known for his genuine enthusiasm in mentoring students. He takes great care in guiding them through the challenges and rewards of scientific inquiry, helping them build the essential skills needed for successful careers in science and engineering. His contributions are characterized by a thoughtful combination of theoretical insight and practical application, establishing him as a respected voice within both academic and professional communities.
