Physics

Geoffrey Lee-Dadswell

Dr. Lee-Dadswell utilizes statistical mechanics to examine how the “macroscopic”, or large scale, properties of a physical system arise from its “microscopic”, or small scale, properties. His main area of interest is transport theory, which is concerned with understanding how quantities such as heat, momentum and magnetization propagate through physical systems.  Dr. Lee-Dadswell is particularly interested in heat transport in nanoscopic systems with “reduced dimensionality” such as carbon nanotubes and polymer chains.  This area contains many unsolved fundamental problems and is also of practical interest for the development of nanoelectronic devices.

Dr. Lee-Dadswell has previously explored classical acoustics; in recent work he  investigated whether seismic testing has any impact on invertebrates. This study established the necessary theoretical work to guide future experiments which will examine the physical effects of seismic testing on invertebrates such as the snow crab.

Mathematics

Shaohua (George) Chen – NSERC, CFI, NSRIT

Dr. Chen’s research area is in partial differential equations and its applications, which consist of two parts, one is the theoretical analysis and the other is numerical analysis, including simulations and scientific computations.

Dr. Chen is interested in the global existence and blow-up solutions of the time dependent partial differential equations, mathematical modeling and applications related to ordinary and partial differential equations, such as reaction-diffusion equations, traveling waves, solution and shock waves, radar beams and heat transfer and fluid dynamics.

Scott Rodney

Dr. Rodney’s NSERC funded research interests are in partial differential equations (mostly elliptic and degenerate elliptic) and analysis.   There are three main focuses to his research: the existence of solutions,regularity properties of solutions, and properties of degenerate Sobolev spaces.

Geology

Deanne van Rooyen

Dr. Van Rooyen’s research focuses on structural geology, geochronology, and tectonics. Her projects investigate deformation and metamorphism in ancient mountain belts at multiple scales, from microstructure in rocks, to how mountains evolve in time and space, and how continents are amalgamated. Her most recent project is a 3-year collaboration with the Geological Survey of Canada in the Kuujjuaq area of Northern Quebec near Ungava Bay where she will be investigating the rocks from the 1.8 billion year old New Quebec Orogen. This research is funded by the Geomapping for Energy and Minerals program (GEM-2) of Natural Resources Canada, in part as a Task Share Agreement for collaboration, and in part as an individual academic grant from the GEM-2 program. She is also involved in research based on Cape Breton Island, and the Monashee Mountains of British Columbia.

Jason Loxton

A biostratigrapher and invertebrate paleontologist, Mr. Loxton’s research focuses on understanding ecosystem and evolutionary responses to the Late Ordovician Extinction. He is currently collaborating with a team of Canadian and American researchers on a broad project to understand the role that ecological factors, such as depth zonation, had on survivorship probabilities of graptolites, an group of colonial zooplankton that are important index fossils during the Ordovician and Silurian.
