The Haynes Research Group

Haynes Lab Group Members

Haynes Group in July 2009

Principal Investigator: Dr. Christy L. Haynes

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.

Dr. Haynes' curriculum vitae is available.

Group Alumni

Postdoc: Dr. Adam D. McFarland

Adam is now a research scientist at Eli Lilly. He joined the Haynes research group as an expert in Raman spectroscopy ready to explore the synthesis and transport of neurotransmitters inside cultured neuronal cells.

Adam earned his B.S. at the University of Dayton (1999) and his Ph.D. in the Van Duyne group at Northwestern University (2004). He performed one year of postdoctoral research in the Hersam group at Northwestern University (2005) before joining the Haynes lab.

Dr. McFarland's curriculum vitae is available.

Postdoc: Dr. Nathan Wittenberg

Nate joins the Haynes Lab after a postdoctoral stint at the University of Edinburgh in Scotland.
