EEWR Brown Bag Seminar with Professor Mark Zondlo and Peter Jaffe
Speaker: Professors Mark Zondlo and Peter Jaffe
Series: EEWR Brown Bag Seminars
Location: Engineering Quad E219
Date/Time: Friday, October 15, 2010, 12:00 p.m. - 1:00 p.m.
Professor Mark Zondlo, Atmospheric Chemistry Lab
Professor Zondlo’s group conducts research in global climate change and air quality by deploying novel optical sensors in the atmosphere and analyzing the data as part of field campaigns on local to global scales. Water vapor and ammonia are examples of two important trace gas species that are critical to aerosol and cloud particle processes. Recent advances in laser-based sensors allow for unprecedented capabilities to observe these and other trace gases in the atmosphere. Instrumentation developed in the laboratory is deployed as part of international field experiments on aircraft-, network-, and ground-based platforms. Specific research areas include cloud and aerosol particle formation, trends and distribution of water vapor in the atmosphere, and emissions of greenhouse gases to the troposphere.
Professor Peter Jaffe, Environmental Biogeochemistry Research Group
Professor Jaffe’s research interests relate to the physical, chemical, and biological processes that govern the transport and transformation of pollutants in the environment and their application toward the remediation of contaminated systems. Areas of current emphasis include laboratory and field experiments as well as mathematical simulations of biogeochemical processes in porous media, such as:(1) numerical simulation of denitrification in soils as a function of rainfall and soil properties, and the scaling of these results to link them to climate change models; (2) biogeochemically mediated dynamics of trace metals in sediments, wetland soils, and groundwater; (3) biological reduction of uranium in groundwater and the long-term stability of the reduced uranium phases; (4) nitrogen processing in urban settings coupled to urban hydrology; and (5) effects of carbon dioxide sequestration in deep aquifers on shallow soils due to potential leaks. Professor Jaffe has served on numerous committees and panels, including the National Research Council, EPA, NIH, and DOE.
