Philip Graybill joined the faculty at Messiah University in 2022. He previously taught at Penn State Altoona and served as a teaching assistant at Penn State’s University Park campus, where he was awarded a Harold F. Martin Graduate Assistant Outstanding Teaching Award in 2019. Phil interned at Los Alamos National Lab (LANL) in 2016 and also at LANL’s partner institute at Chonbuk National University in South Korea in 2017.

Phil grew up in south-central Pennsylvania and followed his siblings’ footsteps to Messiah University, where he earned a bachelor’s degree in music education with a concentration in voice in 2005. After several years working in an unrelated field, Phil returned to school to earn a second bachelor’s degree in electrical engineering from Penn State in 2016. He continued at Penn State for his PhD, which he received in 2022. His research interests include embedded systems for biomedical applications, assistive technology, unscented Kalman filtering, sleep state prediction, and academic integrity among engineering undergraduates.

Phil enjoys spending time with his extended family. He is an active member of Holy Apostles Orthodox Church, where he sings in the choir. His other interests include classical music, fitness, theology, ping pong, and Penn State wrestling.
