Dr James M May, Principal Investigator

Dr May received a Bachelors degree in Biology from Yale College and then attended medical school at Vanderbilt. Following a residency at Johns Hopkins Hospital in Baltimore, a Fellowship at the University of Washington in Seattle, and research at the Medical College of Virginia, Dr May returned to Vanderbilt to set up a research lab in 1986. Dr May is a practicing clinician in endocrinology at the VA but devotes the majority of his time to research.

Current Funding:

  • R01 NS057674-01A2; 2008-2012; NIH/NINDS; Vitamin C Transporters in the Brain
    The project examines the role of the neuronal SVCT2 transporter in maintaining brain ascorbate concentrations and in protecting against oxidant stress generated in mouse models of combined deficiencies of vitamins C and E.
  •  R01 DK050435-14; 2006-2011; NIH/NIDDK; Ascorbic Acid Function and Metabolism
    The goal of this project is to study the role of ascorbate in the development of atherosclerosis related to mouse models and the cells involved, including endothelial cells, macrophages, and smooth muscle cells.
