Mass Spectrometry

Quillen College of Medicine

About Us

The Proteomics and Mass Spectrometry Facility at ETSU was started by Dr. William L. Stone in 2007. We are located in Building 119 (see interactive map) at the James H. Quillen College of Medicine, East Tennessee State University, in Johnson City, TN 37614. Our facility is dedicated to provide a wide variety of mass spectrometry related services to all interested researchers at the ETSU as well as to outside users. The Center serves as a resource offering analytical and instructional expertise in contemporary mass spectrometric techniques with the primary goal of providing investigators with access to "state-of-the-art" LC/MS instrumentation, expert consultations and "hands-on" training (if needed) to meet their research interests.



William L. Stone, Ph.D.     

Facility Director

Dr. Bill Stone is the Director of Pediatric Research and his research focuses on free radical biology and medicine (pediatrics, cancer and cardiovascular disease) with emphasis on nutritional antioxidants as well as proteomics. The Pediatric Research Laboratory has developed state-of-the-art techniques for evaluating oxidative stress and antioxidant status in human subjects and in various model systems. Dr. Stone received both his B.S. (Chemistry, 1966) and Ph.D. (Molecular and Cellular Biology, 1972) degrees at State University of New York at Stony Brook. Postdoctoral training was completed in the Biochemistry Department at Duke University Medical Center. Dr. Stone's predoctoral and postdoctoral works were in the area of physical chemistry of macromolecules with particular emphasis on hydrophobicity and forces stabilizing lipid-protein complexes (biological membranes and plasma lipoproteins). Dr. Stone joined the Department of Pediatrics at ETSU in 1989, serves as the Director of Pediatric Research and teaches a graduate level course in Proteomics.
