Professor Sadeghi, after receiving his Ph.D. in 1986 from the Department of Mechanical Engineering at North Carolina State University, joined the School of Mechanical Engineering at Purdue University and founded the Mechanical Engineering Tribology Laboratory (METL).

As the director of METL he has lead the laboratory to prominence and as one of the leading tribology laboratories in the world. His research interest includes lubrication, friction and wear of rolling and sliding surfaces, rolling contact fatigue, surface science, dynamics, and MEMS for tribological applications. He has authored and co-authored over 165 archival publications and three book chapters in leading international journals and has numerous presentations at various conferences, industries and governmental agencies.

Professor Sadeghi has graduated 79 PhD. and M.S. and students, currently serving as the chair of 10 Ph.D. and 1 M.S. students. Professor Sadeghi has received more than $30M in research grants and contracts from governmental agencies and industrial companies.
