Previous Keynote Speakers
J. (Dick) Haynes
The University of Queensland, Australia
Professor Haynes works in the areas of soil and environmental science. His present research interests are in the use and recycling of industrial, agricultural and municipal wastes and minimising their effects on the environment. He has extensive experience having worked as both an applied research scientist and as a university professor and has worked in New Zealand, South Africa and Australia. He has published over 170 original research papers in international journals, over 20 review papers in international volumes as well as many conference and extension papers and contract reports. He has been an invited keynote speaker at 7 international conferences and has served on the editorial board of 4 international research journals. He has acted as principal supervisor and co-supervisor of PhD, MSc and honours students in both South Africa and Australia. Professor Haynes has carried out research in commercial horticultural, pastoral, arable and forestry production as well as in small-holder semi subsistence agriculture. He has also worked on bioremediation of soils contaminated with organic pollutants, rehabilitation of mined sites, application of organic and inorganic wastes to soils and the effects of heavy metal contaminants on soil processes. His research has been mainly in the areas of applied soil chemistry and soil microbiology/biology with links to soil physical properties and to pollution of air and water. He has specialised in working on applied problems and maintains strong links with industry. Major areas of research have included the role of grazing animals in the fertility of pastoral soils, N cycling and gaseous and leaching losses from arable and pastoral systems, soil quality and soil degradation under agricultural land use, effects of soil contaminants on soil processes, rehabilitation and remediation of contaminated, degraded and mined sites and use of wastes as soil amendments.
Prof. Chris Frey
North Carolina State University, USA
Adjunct Professor, Division
of Environment and
Hong Kong University of Science and Technology
H. Christopher Frey is a professor of environmental engineering in the Department of Civil, Construction, and Environmental Engineering at NC State. His research interests are measurement and modeling of real-world fuel use and emissions of onroad and nonroad vehicles; modeling and evaluation of advanced energy conversion (e.g., combustion, gasification) and environmental control systems; development and application of methods for quantification of variability and uncertainty and for sensitivity analysis in environmental systems models; and exposure and risk analysis. He teaches courses on air pollution control, environmental exposure and risk assessment, and sustainable infrastructure. He is also an adjunct professor in the Division of Environment and Sustainability at the Hong Kong University of Science and Technology, where he has taught on urban air quality and conducts research on exposure to air pollution.
Dr. Frey was Chair of the U.S. Environmental Protection Agency’s Clean Air Scientific Advisory Committee (CASAC) from 2012 to 2015. He chaired CASAC review panels on ozone, nitrogen dioxide, and lead. He has served on CASAC review panels for all six criteria air pollutants, including ozone, particulate matter, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. He was a member of the U.S. EPA Science Advisory Board from 2012 to 2018. He current serves on an advisory committee on EPA’s “MOVES” vehicle emission factor model. He has served on the Board of Environmental Studies and Toxicology of the National Research Council, an EPA Science Advisory Board panel on expert elicitation, National Research Council committees on review of the toxicological assessment of tetrachloroethylene and of EPA’s New Source Review program, a NARSTO assessment of multipollutant air quality management, and a World Health Organization working group on uncertainty in exposure assessment. He was a lead author for 2006 guidance by the Intergovernmental Panel on Climate Change (IPCC) regarding uncertainty in greenhouse gas emission inventories. He currently serves as a member of the Transportation and Air Quality Committee (ADC20) of the Transportation Research Board and on the Editorial Board of the journal Atmospheric Environment. He is a member of the Publications and Critical Review committees of the Air & Waste Management Association. In 2018, he wrote and delivered the 48th Annual A&WMA Critical Review on “Trends in Onroad Transportation Energy and Emissions.”
Dr. Frey is a Fellow and Past President of the Society for Risk Analysis and a Fellow of the Air & Waste Management Association. Recent awards include the 2019 Frank A. Chambers Award of the A&WMA for excellence in air pollution control. Dr. Frey has a B.S. Mechanical Engineering from the University of Virginia, and from Carnegie Mellon University he has a Master of Engineering in Mechanical Engineering and PhD in Engineering and Public Policy.
