Professional Education BSc, Technion, Aeronautical Engineering (1964) MSc, Technion, Aeronautical Engineering (1971) DSc, Technion, Aeronautical Engineering (1974) Main academic Appointments Professor Emeritus, Mechanical Engineering, Technion (2010-present) Main Research Interests In the early years of his academic career Professor Etsion research focused on fluid mechanics aspects of tribology. He developed original solutions for gas bearings and made pioneering contributions in the area of mechanical seal dynamics. He then started to study solid mechanics aspects of tribology and made some breakthrough contributions in modeling contact, adhesion, and static friction of rough surfaces. Professor Etsion invented in 1996 the laser surface texturing (LST), which is now recognizes worldwide as a promising technology for energy conservation. HE also made original contributions in micro/nano-tribology and in bio-tribology. He is the author and co-author of more than 200 scientific archival publications (h-index 52 as of January 2022) and the inventor and co-inventor of 15 patents. He supervised more than 50 graduate students, supervised scientists from the former USSR that immigrated to Israel, and collaborated with scientists from many nations. His current research focus in on: modeling of coated rough surfaces aiming at optimizing coating thickness for best tribological performance.
