Dr. Clayton TeagueDr. Greg Lowry is a Professor of Civil and Environmental Engineering at Carnegie Mellon University. He teaches courses in Environmental Engineering, Environmental Fate and Transport of Organic Compounds in Aquatic Systems, Environmental Nanotechnology, Water Quality Engineering, and Environmental Sampling and Sample Characterization.

His research interests broadly include Environmental Nanotechnology, Energy and Environment, and Environmental Remediation. Specific research areas include nanoparticle characterization, reactivity, and transformations, macromolecule-nanoparticle interactions, and contaminant fate in the subsurface.

He is an experimentalist working on a variety of fundamental and application-oriented research projects including developing nano-enabled environmental technologies, assessing environmental fate of engineered and natural nanomaterials and organics, and understanding the impacts of CO2 on deep subsurface biogeochemistry.

Lynn L. BergesonDr. Paul Tratnyek is a Professor at the Oregon Health and Science University in the Institute of Environmental Health; Division of Environmental and Biomolecular Systems. He is an Affiliate Scientist in the Center for Groundwater Research.

Dr. Tratnyek's research interests include pathways, kinetics, mechanisms, and other fundamental, molecular aspects of environmental oxidation-reduction reactions; the contribution of these reactions to the fate of organic substances under natural conditions, and the enhancement of these processes for application in remediation technologies; the development of quantitative structure-activity relationships (QSARs) for explaining and predicting the properties that affect environmental fate.

His recent research addresses use of nanomaterials in environmental remediation.
