In addition, Dr. Nyblade has served as Director of AfricaArray since its launch in 2004. AfricaArray is an innovative program to promote, strengthen, and maintain a workforce of highly trained African geoscientists and researchers for Africa. It combines student education with establishment of a research program in geophysics, field schools attended by African and American students and corporate personnel, and a graduate exchange program.
Dr. Parizek, Associate Professor in Mathematics and Geosciences at Penn State DuBois and member of the Geosciences Graduate Faculty, presents "Simulating Ice-Sheet Dynamics: (De)Coding the Sea-Level-Rise Bombs" on Tuesday, November 18th, at 4 PM in 022 Deike. A pre-talk Coffee & Cookies Speaker Reception will take place at 3:45 PM in the EMS Museum on the ground floor of Deike. All are welcome.
Dr. Parizek obtained his M.S. and Ph.D. in Geosciences and B.S. in Physics with a minor in Mathematics at the Pennsylvania State University. His research interests relate to physical processes in the Earth Sciences and have lead to travel to locations as diverse as Antarctica and Abu Dhabi. In addition to a focus on glaciological studies, he also has many years of field experience in hydrogeology. Dr. Parizek has served as the Lead PI, Co-PI, or Co-I on eight NSF and NASA grants from 2005-Present, was the recipient of the 2011 Delta Mu Sigma Honor Society’s Susanne Waitkus Faculty Award for Academic Excellence, and was twice nominated for the prestigious Schreyer Teaching Award. He a member the Penn State Ice and Climate Exploration (PSICE) Center and The Polar Center.
Dr. Bullock's talk is entitled "The Solar System's First Dust Bunnies." Prior to the November 11th talk, a Coffee & Cookies Speaker Reception will take place at 3:45 PM in the EMS Museum on the ground floor of Deike.
Dr. Bullock obtained her undergraduate degree in Geochemistry from the University of Manchester, followed by a Ph.D. at the Open University (England). Before joining the Smithsonian, she worked at the Natural History Museum, London, where she studied aqueous alteration in primitive meteorites. Her research is focused on refractory inclusions and early solar system chronology.
Dr. Kelemen's talk is entitled "Emulating Natural Systems for Geologic CO2 Capture and Storage and to Enhance Subsurface Permeability." Prior to the November 4th talk, a Coffee & Cookies Speaker Reception will take place at 3:45 PM in the EMS Museum on the ground floor of Deike.
Dr. Kelemen received his Ph.D. in Geology from the University of Washington. His current research is focused on reactive transport of lava through the Earth’s upper mantle and lower crust, genesis and evolution of oceanic and continental crust, new mechanisms for earthquake initiation, geologic capture and storage of CO2 (CCS), and reaction-driven cracking in natural and engineered settings. He was a founding partner of Dihedral Exploration (1980-1992), consultants specializing in exploration for mineral deposits in Canada, Alaska and Greenland. Dr. Kelemen's worldwide research has taken him from7,500 meters above sea level in Pakistan to 5,500 meters below sea level via submersibles along the Mid-Atlantic Ridge. He was recently elected to the National Academy of Sciences, one of the highest honors accorded to a scientist or engineer in the United States.
Geosciences Colloquium Speaker, Dr. Pincelli Hull, Assistant Professor of Paleontology, Department of Geology and Geophysics, Yale University, presents "Resolving Communities Through Time: The Promise and Challenge of Measuring Biotic Sensitivity in Cenozoic Oceans" on Tuesday, October 28th, at 4 PM in 022 Deike. A pre-talk speaker reception will take place at 3:45 PM in the EMS Museum on the ground floor of Deike. All are welcome.
Dr. Hull received her Ph.D. from the Scripps Institution of Oceanography, University of California at San Diego and a B.S. in Biology from Duke University with post doctoral research in Germany and at Yale University. She also spent a college semester at sea with the Sea Education Association, studying oceanography, nautical science and maritime history. Dr. Hull is broadly interested in the evolution and ecology of open ocean ecosystems and species over long-time scales as these are the scales on which species evolve and go extinct and ecosystems collapse and reassemble. The Hull Lab focuses on understanding open ocean ecosystems through the Cenozoic (the last 65 million years), disentangling the causes and consequences of mass extinctions and quantifying community response to global change. Her goal is to understand how species, communities, and ecosystems are shaped by large infrequent events like mass extinctions and climate change and how such events affect the history of life. Ultimately, the group hopes to gain some insight into how Earth’s biota will respond to the profound, widespread human-caused environmental and climatic changes of today.
On Tuesday, October 21st, Geosciences Colloquium Speaker, Dr. Sarah Brownlee, Assistant Professor, Department of Geology, Wayne State University, presents "Seismic Anisotropy as a Tool for Improving Understanding of Composition and Structure in the Continental Crust" at 4 PM in 022 Deike Building. A pre-talk speaker reception will take place at 3:45 PM in the EMS Museum on the ground floor of Deike. All are welcome.
Dr. Brownlee received a B.A. in Geosciences from Princeton University and a Ph.D. in Earth and Planetary Sciences from the University of California at Berkley. Her fields of specialty are geochemistry and geophysics. Dr. Brownlee's research interests include the study of the structure, composition, and elasticity of middle and lower crustal materials. She is currently working to understand seismic anisotropy in the lower continental crust along with time and length scales of processes governing transport of material through the crust. She uses a combination of thermochronology, paleomagnetism, analytical techniques, and numerical modeling in her research.
