Professor
Department of Engineering, Computer Science, & Physics

Dr. Mendelsohn grew up in the Cleveland area and attended Boston University and did his graduate work at Northwestern University. After a stint as a research scientist for Halliburton Services he was a professor in the Departments of Engineering Mechanics and Mechanical and Aerospace Engineering at The Ohio State University from 1982 until his retirement from OSU in 2017. His research interests are in wave propagation, vibrations and fracture mechanics of solids, and he also served as Undergraduate Studies Chair and then Associate Chair of Mechanical and Aerospace Engineering from 2005 to 2017. Since then he has been a STEM consultant for K-12 education, and an adjunct professor of mathematics at Columbus State Community College. He joined the faculty of the Department of Engineering at Otterbein University in the summer of 2018. He is an avid amateur guitarist and vocalist and lover and collector of music of all kinds.
