Instructor Bios:

Johnson-TimTim Johnson has a Bachelor’s degree in Physics from Macalester College in St. Paul Minnesota. He has worked at TSI Incorporated for over 38 years and has worked with the Automated Filter Tester products for over 26 years. He is currently Senior Application Engineer in the Particle Instruments product group. He is responsible for the product applications using automated filter test equipment and components used in filter testing applications.  He is actively involved in filtration standards development in the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE), and at the international level (ISO/TC142).

Dr. Thad Ptak has over 30 years of experience in filtration technologies, aerosol science and indoor air quality. He has conducted extensive research in the areas of particulate technology, aerosol science, air quality, instrumentation for particle generation and measurement.

Currently he is VP of Research and Development at Columbus Industries. At this position he is responsible for the advanced research projects in air and liquid filtration. Prior to joining Columbus Industries in 2005, he served as VP of R&D of StrionAir, company developing advanced air purification systems based on utilization of electrostatic field.

Prior to StrionAir Thad worked on development new filtration applications, products and technologies in consumer products, commercial and residential HVAC, industrial filtration and automotive filtration applications for several different companies.

Dr. Ptak has published more than 50 technical papers related to the particle technology and filtration field, chaired and organized several sessions and co-chaired a filtration conference. He actively participates in technical societies and numerous standard committees.

Kenneth Rubow is Vice President for Filtration and Advanced Media Science at Mott Corporation. He received his BS, MS and Ph.D. in mechanical engineering from the University of Minnesota. Prior to joining Mott in 1995, he worked at the University of Minnesota in increasingly responsible positions for 22 years. He also served as a consultant for more than 30 companies and government agencies in the areas of particle technology and particulate filtration.
