Brazier

Rick Brazier

Richard Brazier
Associate Professor of Geoscience and Mathematics

Research Statement: My research is both mathematical and geophysical in nature.  Currently, I am using genetic algorithms on seismograms from earthquakes to model the structure of the Earth beneath Africa.  In addition, I am developing criteria to ascertain if an earthquake location is accurate to within 5 km.  This is the radius needed for the international nuclear monitoring community to search for nuclear explosion.  Identified, accurately located earthquakes also aid in discriminating between earthquakes and nuclear explosions.

Associate Professor of Biology and Forestry

Research Statement: Based on my doctoral research in biology, geography and geology at New York University, I examine long term forest ecology in urban and urbanizing areas as the focus of my research.  Utilizing an interdisciplinary approach that combines research in forest composition resampling and comparison, fossil pollen studies, and primary historical sources, I examine the relationships between human activities and forest changes.  The management of urban forests from the historical and developmental perspectives is the applied component of the research.

Associate Professor of English

Research Statement: My work involves the study of physical and textural evidence in eighteenth-century books to establish what authors and printers did and where, when, how, and why they did it.  I try to explain why printed works have the texts and physical features they have.  I have described and analyzed the publication history, defining the author's revisions, the publisher's marketing strategies, and the press's corruptions, for works such as Tobias Smollett's histories of England, in "The Authoritative Editions of Smollett's Complete History of Egnland" in Tobias Smollett, Scotland's First Novelist (2007) and "The Publication and Revision of Tobias Smollett's Continuation of the Complete History of England, 1760-1771" in New Contexts for Eighteenth-Century British Fiction (2011).

Byron R. Parizek
Associate Professor of Geosciences and Mathematics

My primary focus is on numerical modeling of ice-sheet dynamics and related Earth-system processes.  I have been fortunate to work with outstanding students and colleagues as we develop process-oriented models that are tightly coupled to ongoing field and space programs to address hypotheses ranging from the source and timing of off-shore paleo-sedimentation in the North Atlantic to the future stability of the West Antarctic and Greenland ice sheets.  Our collaborative research highlights the importance of atmosphere-ice-ocean-solid Earth interactions, nonlinear dynamic feedbacks, and improved understanding of bedrock topography, basal rheology, and grounding-zone processes for reliable predictions of ice-sheet evolution and the cryospheric contribution to sea level.

Instructor in Wildlife Technology

My research examines the effects of conventional oil and gas development on abundance and nest success of songbirds.  Conventional oil and gas wells are prevalent in western Pennsylvania, and my work has focused on the Allegheny National Forest, where over 14,000 wells are active.  I have been fortunate to involve students in my research and to collaborate with both the US Forest Service Northern Research Station's Forestry Sciences Laboratory in Irvine, PA and Ecosystem Science and Management faculty at Penn State University Park.

Assistant Professor of Engineering

My work deals with the thermo-mechanical processing, synthesis, and characterization of metallic materials, and aims to estbalish the relationships between the structure, properties, processing, and performance of these materials.  I have used experimental and numerical modeling methods to investigate and elucidate the mechanics occurring during plastic deformation, recrystallization, and grain growth, and factors and mechanisms responsible for the formation and development of deformation and recrystallization texture, microstructure, and grain boundary structure.  Some of the materials studied include copper alloys, aluminum alloys, titanium alloys, tantalum, niobium, and steels.  Recently, my interests have encompassed optimization of properties in sintered powdered materials.
