Associate Directors


W. Hayes McDonald, Ph.D.

Research Assistant Professor, Department of Biochemistry
Assistant Director of the Proteomics Core Laboratory

Hayes has been with the MSRC Proteomics Laboratory as a co-Associate Director since June 2008.  After earning his Ph.D. in Cell and Developmental Biology at Vanderbilt in 1998, he began his work in proteomics with John Yates at The Scripps Research Institute and continued as a scientist at Oak Ridge National Laboratory. Hayes has expertise in the design and implementation of shotgun and targeted proteomics experiments, particularly in relation to protein complexes, MS-informatics, and quantitative LC-MS/MS.


Kristie Lindsey Rose, Ph.D.

Research Assistant Professor , Department of Biochemistry
Associate Director of the Proteomics Core Laboratory

Kristie received her Ph.D. in Pharmacology at the Medical University of South Carolina in 2005. She completed a post-doctoral fellowship at the University of Virginia, where she specialized in mass spectrometric analysis of peptides and proteins,and continued as a research scientist in the Proteomics Core at The Scripps Research Institute in the Department of Molecular Therapeutics. Kristie joined the MSRC Proteomics Core as co-Associate Director in 2010 and is a Research Assistant Professor in the Department of Biochemistry. She has expertise in discovery-based quantitative proteomics, particularly label-based methods using isobaric tagging and metabolic labeling, characterization of post-translational modifications, and analysis of intact proteins.
