Matthew Claassen is a research scientist at the Desert Research Institute (DRI) in Reno, Nevada and a graduate student in Mechanical Engineering at the University of Nevada, Reno (UNR). He previously obtained his Bachelors degree at UNR in Engineering Physics with a minor in unmanned autonomous systems. His research at DRI focuses on particulate air pollution and monitoring. He also builds and maintains software and database infrastructure for the Environmental Analysis Facility at DRI. His other interests include machine learning and robotics, as well as an interest in spacecraft and space missions. In his free time, Matthew enjoys mountain biking, rafting, and skiing in the mountains surrounding Reno.
Judith C. Chow, Nazir and Mary Ansari Chair in Entrepreneurialism and Science and Research Professor in the Division of Atmospheric Sciences (DAS) at the Desert Research Institute, has more than 40 years of experience in atmospheric, air quality, and environmental health research and education. Chow is a member of the graduate faculty in the Department of Environmental Science and Atmospheric Sciences Program in the Department of Physics at the University of Nevada, Reno (UNR). Her current strategic priorities include expansion of EAF capabilities to obtain more information from archived samples of existing monitoring networks using thermal and mass spectrometric technologies; improving detection of brown carbon in speciation network samples; applying microsensors to human exposure estimates and fugitive dust control; and simulating source profile changes using a
photochemical flow tube reactor. Chow was re-appointed to as one of seven chartered members on the U.S. EPA’s Clean Air Science Advisory Committee in 2021, after previous service from 2015-2018. She served on the Board of directors for the Air & Waste Management Association, chaired the Editorial
Review Board for the Journal of the Air & Waste Management Association, and is currently a co-editor-for Aerosol and Air Quality Research and Particuology.
John G. Watson research includes: 1) evaluating, characterizing, and advancing methods to measure carbonaceous material in suspended particles; 2) developing and applying real-world, multipollutant
emission measurement technologies; and 3) designing and conducting aerosol characterization, source apportionment, and adverse effects studies. Watson has organized and presented mini-courses and symposia related to aerosol measurement and source apportionment in various parts of China, Hong Kong, Macao, Taiwan, various parts of India, Viet Nam, Egypt, South Africa, Mexico, and Chile. He is one of 250 highly-cited authors in the energy and environment section of ISIHighlyCited.com and is
listed in the 2021 Stanford University's Top 2% of Most-Cited Scientists. Watson co-chaired the National Academy of Engineering panel on Energy Futures and Urban Air Pollution Challenges for China and the United States and was a member of the National Academy of Science panel on New Source Review for Stationary Sources of Air Pollution. He authored the Air & Waste Management
Association (A&WMA) 2002 critical review on Visibility: Science and Regulation, the 2017 critical review on Air quality measurements From rubber bands to tapping the rainbow, and has served on the A&WMA Critical Review committee since 1982.
Dr. Xiaoliang Wang is a research professor in the Division of Atmospheric Sciences at the Desert Research Institute (DRI). He completed his B.E. degrees in Thermal and Environmental Engineering at Tsinghua University, and his M.S. and Ph.D. studies in Mechanical Engineering at the University of Minnesota. Before joining DRI, he worked for TSI Inc. as a senior engineer and developed a suite of aerosol instruments. His research interests include physical and chemical characterization of aerosols,
pollution source emission measurement, and instrument development.
