Biography

Dr. Theo Keith is one of ten University of Toledo Faculty members, and only the second Engineering College Faculty member, to hold the rank of Distinguished University Professor. He was elected to this rank in 1991 and re-appointed in 1996.

Dr. Keith received a BME degree from Fenn College (Cleveland State University) and an MSME and Ph.D. from the University of Maryland in College Park Maryland. His field of study was in the thermal sciences (fluid dynamics, heat transfer and thermodynamics).

Dr. Keith worked as civilian employee of the U.S. Navy at the Naval Ship Research & Development Center in Annapolis Maryland for over 7 years. His research work involved the numerical simulation of the emergency ballast–blow system of a nuclear submarine and the analysis of the propulsion systems of various surface watercraft.

Dr. Keith joined the Mechanical Engineering Department faculty at the University of Toledo in 1971. He was appointed the Department Chair in 1977 and served in that capacity until 1985. Dr. Keith has taught over 45 different courses at the graduate and undergraduate levels. He has authored/co-authored more than 180 articles in archival journals and conference proceedings. He has been the advisor/co-advisor of 22 completed Ph.D. dissertations and 3 current Ph.D. candidates and 41 completed MS theses and 4 MS candidates. He has received external funding for over 160 projects totaling more than $10,000,000. He has worked with 15 postdoctoral researchers.

Recently, Dr. Keith received a grant from the Ohio Board of Regents for $1, 235,000 in order to develop a consortium of 5 universities tribology laboratories (the University of Akron, Cleveland State University, Case Western Reserve University, the Ohio State University, and the University of Toledo. The group is called the ULTRA Consortium, which stands for University Laboratories in Tribology Research and Application. This group is expected to develop a world-class set of tribology laboratories in the state of Ohio that will be of significant benefit to industry. Moreover, ULTRA is expected to lead to a new spirit of collaborations between the participating university researchers.

Dr. Keith has received several honors and awards. In 1977 he received a University of Toledo Outstanding Teaching Award. In 1978 he received a Ralph R. Teetor Award from SAE. In 1988 he received the University of Toledo Outstanding Research Award and in 1989 the D. Raftopolous Sigma Xi Award for Research. He is an Associate Fellow of the AIAA and a Fellow of the ASME. He is an Associate Editor of the STLE’s Lubrication Engineering and is a member of the Editorial Board of The International Journal for Numerical Methods in Heat and Fluid Flow.

Dr. Keith is active in the AIAA and has been involved with the organization of a number of national and local meetings and workshops. He is the Technical Chair of the 34thAIAA/ASME/SAE/ASEE Joint Propulsion Conference that will be held in Cleveland Ohio in July 1998. He is member of the Executive Committee of the Northcoast Section of the AIAA. He is also a member of ASME, ASEE, STLE and Sigma Xi. Dr. Keith started the SAE student club at the University of Toledo.

Dr Keith has a joint appointment at the Ohio Aerospace Institute (OAI) in Cleveland, Ohio where he is the Vice-President of Workforce Enhancement. He joined OAI in 1990 as a visiting faculty member and has held a variety of positions within the Institute. OAI is a consortium of nine universities (the University of Akron, Cleveland State University, Case Western Reserve University, Cincinnati University, the University of Dayton, the Ohio State University, Ohio University, Wright State University and the University of Toledo), 2 federal laboratories (the NASA Lewis Research Center and Wright Paterson Air Force Laboratory) and a number of aerospace/technology companies. Dr. Keith is the OAI Director of the Institute for Computational Mechanics in Propulsion, a co-director of the NASA Lewis Summer Faculty Fellow Program, the OAI Director of the NASA/OAI Summer Intern Program, Advisor to the Ohio Space Grant Consortium, Director of the NASA On-Site Graduate Education Program, and the host of the OAI Distinguished Lecture Program.
