David Kittelson profile

David B. Kittelson

Mechanical Engineering, University of Minnesota

Professor Kittelson has worked for more than 40 years on improving performance and reducing emissions from engines. Current research interests include sampling and characterization of ultrafine and nanoparticles from engines, development of new methods for measuring solid particles, measurement of vehicle emissions using mobile platforms, measurement of performance and emissions of engines operating in advanced low temperature combustion modes, use of hydrogen rich gases to modify combustion in engines, measurement of particles from aircraft engines, development of advanced engine exhaust aftertreatment systems, reducing fuel use and greenhouse emissions from transportation, production and use of biofuels including biodiesel, butanol, DME, Fischer-Tropsch liquids, ethanol, and biocrudes, and development of fast response sensors for engine control. He is a Fellow of the Society of Automotive Engineers.

Thomas Kuehn profile

Thomas H. Kuehn

Professor Emeritus
Department of Mechanical Engineering at the University of Minnesota

Professor Kuehn has over 40 years’ experience with indoor and outdoor air quality measurements and modeling. Applications have ranged from semiconductor manufacturing clean rooms to industrial dust collectors. His work characterizing cooking emissions is now used as the basis for improved emission controls on restaurants and other commercial kitchens and has led to new standards and governmental regulations. He has also performed pioneering work on bioaerosols including fungi, bacteria and, more recently, viruses, and studied the airborne transmission of disease for both animal populations and humans. Professor Kuehn is a Fellow of the American Society of Mechanical Engineers (ASME) and the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE).
