Jeffrey Karson /faculty-experts/jeffrey-karson/ Thu, 12 Aug 2021 21:02:49 +0000 /?post_type=faculty-experts&p=124403 Jeffrey Karson is Professor: Tectonics & Magmatism of Rifts and Transform Faults Tectonics & Magmatism of Rifts and Transform Faults in the Department of Earth and Environmental Sciences.

His research is focused on the structural and tectonic analysis of rift and transform plate boundaries. investigations of contental extensional terranes, rifted continental margins, Iceland and mid-ocean ridges provide overlapping perspectives on crustal accetion across a spectrum of environments dominated by magmatic construction and mechanical deformation. He uses outcrop-scale data collected from a wide range of research approaches including field geology, drone imaging, and seafloor investigations using submarines, ROV’s, and AUV’s to constrain larger-scale tectonic processes. The cross-pollination of data and processes from different environments helps to provide a more comprehensive understanding of crustal accretion on Earth and other planetary bodies.

Prof. Karson is also one of the leaders of the . The lave pours promote and allow for scientific experiments, artistic creations, education and outreach to the Syracuse University and City communities.

She uses a variety of methods, ranging from geochemical and biological proxies to climate models. Her work focuses on a paleoclimatic perspective, whereby past instances of climate change can be used as ‘natural experiments’ to understand the response of the atmosphere-ocean system to external forcing. Her current projects include analyzing the role of tropical Atlantic variability in forcing Mesoamerican drought, studying the interactions of the midlatitude westerlies and monsoon systems, and analyzing reorganizations of subtropical rainfall during past warm intervals in Earth history.

Douglas A. Frank /faculty-experts/douglas-a-frank/ Thu, 23 Feb 2017 17:12:29 +0000 /?post_type=faculty-experts&p=115042 Professor Frank studies and explores factors that regulate the structure, species composition, biodiversity and energy, and nutrient metabolisms in terrestrial ecosystems. Since 1988, he has researched the effects of grazing ungulates, such as elk, bison, and pronghorn, on the grasslands of Yellowstone National Park, which is home to highly coevolved plant-grazer-soil microbe systems.

He and his team investigate important interactions among these trophic levels, which, in turn, facilitate energy and nutrient flows in Yellowstone grasslands and foster stability of this ecosystem that experiences high chronic levels of grazing.

The Frank Lab utilizes field and laboratory experiments. In the field, he and his team erect ungulate enclosures to create an un-grazed treatment and then compare plant growth and soil processes in grazed versus un-grazed grasslands. In the lab, experiments are conducted in the greenhouse or environmental chambers to determine how mycorrhizae, nutrient availability, and soil microbial composition and diversity may mediate the effect of grazing on plant growth.

Astrocytes are star-shaped cells that play a significant role in neuronal signaling and provide physical and nutritional support for neurons. It’s an area of research that has not been widely studied, and one in which Dr. Hewett has made a significant impact. She has been honored with the Donaghue Investigator Award from the Patrick and Catherine Weldon Donaghue Medical Research Foundation, the American Heart Association’s Established Investigator Award and the American Society for Neurochemistry’s Jordi Folch Pi Memorial Award, among others.

Charles T. Driscoll /faculty-experts/test-charles-t-driscoll/ Mon, 29 Aug 2016 15:40:41 +0000 http://sunews.leibowitz.co/?post_type=faculty-experts&p=103810 Professor Driscoll’s research largely involves characterization and quantifying the impacts of air pollution, such as acid rain, mercury, elevated concentrations of carbon dioxide and associated effects of changing climate and land and water disturbances on the structure and function of ecosystems. Much of his work has focused on forest and associated aquatic resources, including studies at the Hubbard Brook Experimental Forest, NH and the Huntington Forest in the Adirondacks, NY. Recently he has been part of a team quantifying health and ecosystem co-benefits associated with a national carbon standard for power plant emissions.

He also examine effects on wetlands, the Great Lakes, urban ecosystems, coastal waters and the open ocean. Over the past 35 years, he has advanced new analytical techniques, established and maintained long-term measurements and experiments, and developed a series of research and predictive models that simulate transformations of major chemical elements in forest vegetation, soil and surface waters in response to air pollution, climate and land disturbance. Beyond theory, he is interested in testing ‘in situ’ strategies to reverse the damaging effects of acid rain and mercury contamination and eutrophication. Current research includes using models, field experiments and measurements to examine: ecosystem effects of changing climate and acidic, nitrogen and mercury deposition; the effectiveness of “green” water infrastructure in storm water management; and ecosystem restoration.
