Dr. Rubow is Vice President - Engineering, Research and Development at Mott Corporation. He is responsible for directing value-added product development, design and application testing of sintered porous metal devices used in a variety of industrial applications involving both gases and liquids. These devices, which are used worldwide, include filters, filter systems, restrictors, spargers, diffusers, fluidizers, and metering frits. Industries served include semiconductor, chemical, textile, instrumentation, energy and environmental.

He received his BS, MS and Ph.D. in mechanical engineering from the University of Minnesota. His specialization was particle technology and particulate filtration. Prior to joining Mott in 1995, Dr. Rubow worked at the University of Minnesota in increasing responsible positions during a 22-year timespan. He was Manager of the Particle Technology Laboratory, Associate Director of the Center for Filtration Research, and Adjunct Associate Professor of Mechanical Engineering. Prior to joining Mott he also was a consultant and expert witness for more than 30 companies and government agencies in areas of particle technology and particulate filtration.

Dr. Rubow is an international expert in the field of particle filtration and aerosol science. He has conducted extensive research for more than 25 years in the areas of particle technology, aerosol science, air quality and human exposure monitoring. Specific research topics include aerosol filtration, instrumentation for particle generation and measurement, measurement of airborne particulate matter to assess human exposure, measurement of air quality in workplace and ambient atmosphere, research on fugitive dust emissions, air quality measurement in microgravity environments and aboard Space Shuttles, and measurement of particle size distributions and elemental composition. Dr. Rubow has more than 145 technical publications and has edited three books, all dealing with particle technology and filtration. He has two patents dealing with gas filtration products.

He actively participates in nine technical societies, numerous test standard committees and education activities. He recently served on the Board of Directors of two societies and has served on more than 25 society committees. In particular Dr. Rubow served on the Board of Directors of the Am. Filtration and Separations Society (1991-2002) where he served as Chair (1998-99) and is past Chair of the 1991 and Co-Chair of the 1998 annual technical conferences. He also served on the Board of Directors of the Am. Assoc. for Aerosol Research (1997-1999) where he served on the Finance Committee and chaired the Awards Committee.

He is a member of numerous SEMI committees and taskforces, which are responsible for developing test standards for the semiconductor industry: he chairs the Filter Task Force and is a member of the Facilities Committee, Gases Committee, Particles in Distribution Task Force and Gas Purification Task Force. He continues to teach short courses and tutorials at the University of Minnesota and numerous technical conferences covering the topics of filtration and particle technology.
