Stephen Boedo
Associate Professor Phone: 585-475-5214 E-mail: sxbeme@rit.edu Office: 2031 Gleason
Biography Stephen Boedo is Associate Professor in the Department of Mechanical Engineering at the Rochester Institute of Technology, Rochester, New York. Dr. Boedo received a B.A. degree from SUNY Buffalo, and M.S. and Ph.D. degrees from Cornell University. He is also a General Partner in the partnership Tribology Associates specializing in software design and engineering consultation services. For the 2007-2008 academic year, Dr. Boedo served as a Visiting Associate Professor at Cornell University. Dr. Boedo brings to RIT fifteen years of industrial experience along with over twenty years of part-time and full-time teaching experience.
Dr. Boedo specializes in the computer-aided simulation and design of mechanical systems, with activity in three overlapping research areas: tribology, automotive systems, and MEMS. Experimental studies in support of the computational work are also part of his research agenda.
Dr. Boedo’s primary research area pertains to the development of new computational tools to study the behavior of dynamically loaded conformal fluid-film bearing systems. He currently studies the interaction of thin lubricant films with structurally compliant surfaces, including effects of geometric irregularity, lubricant supply, and lubricant cavitation on predicted mechanical system performance. These analytical methods have proven useful to the understanding of automotive engine bearings, the nonlinear behavior of fluid-film rotors, and the lubrication of artificial human joints.
A second research area involves computer simulation and experimental testing of automotive systems and related components. Recent work has included modeling of the vibration characteristics of automotive timing drive systems, along with modeling and experimental testing of a novel impulse turbine design for chain testing systems.
A third research area recently started at RIT is in the area of microactuator design and the tribological characteristics of MEMS bearing systems. He is currently investigating the role of friction and wear on MEMS-scale micromachinery, the study of residual stresses induced from wafer deposition processes, and the effect of geometric and material parameters on the deflection of MEMS-scale thermal actuators.
Dr. Boedo serves as the course coordinator for machine design, computer-aided design, and lubrication. He is also a core faculty member in the Ph.D. Microsystems program.
