He holds a BBA from the University of Oklahoma with a double major in Management Information Systems and Energy Management.
Phil Kauppi
Senior Applications Scientist
Phil entered the air emissions analysis and measurement community over 27 years ago, with his first FTIR field test performed in 1998. He has been an advocate for the use of FTIR-based technologies in a large range of source categories including power generation, cement, chemical, ethanol, catalyst research, wood/paper, biomass, semiconductor, purity analysis, and more. Phil has managed hundreds of field projects and research studies, trained hundreds of individuals on FTIR operation, and actively participates with ASTM and the EPA on FTIR-based methodologies. Phil Kauppi received a B.S. in Chemistry from Central Michigan University.
Trevor Tilmann
Senior Applications Scientist
Trevor Tilmann began his career in 2017 at Prism Analytical Technologies while attending Central Michigan University. At Prism, he specialized in performing FTIR field tests across a wide range of source categories for engineering and compliance purposes. In 2023, he joined Thermo Fisher Scientific as an Applications Engineer for the Max Analytical product line, where he developed and supported applications such as Carbon Capture, Utilization, and Storage (CCUS), Beverage Grade Carbon Dioxide, and Bulk Gas Purity. Trevor has a passion for innovation and specializes in FTIR spectrometry and method development. He holds a B.S. in Chemistry from Central Michigan University.
Charles M. Phillips, Ph.D.
Senior Applications Consultant
Dr. Charles M. (“Mark”) Phillips is Senior Applications Consultant at Ellington Valley Technologies. Dr. Phillips has extensive experience in the spectroscopic detection of gases, with technical positions previously at MAX Analytical Technologies (now a part of Thermo Fisher Scientific), MKS Instruments and Scott Specialty Gases (now Airgas/ Air Liquide Specialty Products).
