Ph.D. Northwestern University, 2003 (Richard P. Van Duyne)
Post Doctorate University of North Carolina, Chapel Hill, 2005 (R. Mark Wightman)
Christy completed her undergraduate work at Macalester College in St. Paul, MN (1998) with a major in chemistry and minors in mathematics and spanish. Christy's doctoral work was done at Northwestern University in Evanston, IL (2003) under the direction of Richard P. Van Duyne. Her doctoral thesis title is "Fundamentals and Applications of Nanoparticle Optics and Surface-Enhanced Raman Scattering."
Before arriving at the University of Minnesota, Christy performed postdoctoral research in the laboratory of R. Mark Wightman at the University of North Carolina, Chapel Hill (2005). Her efforts in the Wightman lab focused on applying microelectrode amperometry to probe single cell exocytosis.
As a faculty member at UMN since 2005, her research group works at the interface of analytical, biological, and nanomaterials chemistry. Christy is currently the Associate Department Head, Associate Director of the Center for Sustainable Nanotechnology, and an associate editor for the journal Analytical Chemistry.
Nanoscience & Materials Chemistry: nanoparticle toxicity and surface-enhanced Raman sensors
Our group studies pressing fundamental and applied problems in nanoscience, environmental science, and immunology using a diverse set of analytical and materials techniques. We fabricate nanoparticles to study and exploit size-dependent phenomena, with applications ranging from drug delivery to in vivo and environmental sensors. Additionally, we combine our knowledge of nanoparticles and biological cells to investigate the potential biological and ecological impacts of nanoparticles added to consumer products. Finally, we apply single cell measurements techniques to probe chemical messenger synthesis and exocytosis in individual cells, including mast cells, chromaffin cells, and blood platelets.
