Rebekah L. Gundry, MSFS,PhD

After obtaining her PhD from the NSF Middle Atlantic Mass Spectrometry laboratory at Johns Hopkins University School of Medicine directed by Dr. Robert Cotter, Rebekah conducted her postdoctoral work at the JHU NHLBI Proteomics Center directed by Dr. Jennifer Van Eyk and spent time studying with Drs. Ruedi Aebersold and Bernd Wollscheid at the ETH, Zurich. This hands-on training in the fundamentals of mass spectrometry fueled her passion regarding the application of mass spectrometry in biomedical research and a strong dedication to educating others in the technology.

Since establishing her research laboratory at MCW in 2010, Rebekah has focused on using mass spectrometry to study pluripotent stem cell biology, cardiomyocyte differentiation, and heart failure. To date, work in the Gundry lab has led to the discovery of novel cell surface markers for several human cell types, including hepatocytes and cardiomyocytes, with relevance to immunophenotyping and immunotherapy. Her research is currently funded by two NIH R01 awards and private foundation grants.

Theodore R. Keppel, PhD

Ted earned his BS in chemistry from Truman State University in his home state of Missouri in 2007. From there, Ted was the first graduate student to study under Dr. David Weis at the University of Kansas. In the Weis lab, Ted applied hydrogen/deuterium exchange mass spectrometry to analyze the conformational dynamics of intrinsically disordered proteins. This work provided conformational insight where traditional structure techniques, such as X-ray crystallography and NMR, were limited.

In 2013, Ted joined Dr. Ron Bose's research group at Washington University School of Medicine. Using mass spectrometry, along with small angle X-ray scattering and other biophysical techniques, he provided evidence that the C-terminal tails of proteins in the epidermal growth factor receptor family were intrinsically disordered.

In 2016, Ted joined Dr. Rebekah Gundry's group as the instrumentation manager and mass spectrometry research project lead. He brings expertise in mass spectrometry method development and project management to his role as the Operations Supervisor for the MS Center.

Michael Pereckas

After earning a BS in chemistry from the University of Illinois Urbana-Champaign, Michael joined the Medical College of Wisconsin's Biochemistry Department in the Protein and Nucleic Acid Shared Facility. At that time, the lab offered N-terminal sequencing by Edman degradation, oligonucleotide synthesis, and peptide synthesis, and over time the instrumentation and services changed with MALDI-TOF being added in 1999.

Over the years, Michael has continually worked to implement new mass spectrometry technologies at MCW, and brings more than 20 years of experience in the analysis of biological molecules.
