Wm. Craig Byrdwell B.Sc., Ph.D.


Dr. Byrdwell received his undergraduate and graduate degrees from the University of Louisville, in Louisville, KY. His dissertation, under the direction of Dr. M.C. Yappert and Dr. Douglas Borchman, was on identification of the ‘Unknown Phospholipid’ in the human eye lens, as well as quantification of human lens fluorophors in normal and cataractous lenses. The unknown phospholipid turned out to be dihydrosphingomyelin, and this was the first time that the primary phospholipid of lens membranes was correctly identified. The eye lens remains the only cellular system known in which this extremely stable phospholipid is the primary component.

Then, Dr. Byrdwell took a post-doctoral position at the USDA’s National Center for Agricultural Utilization Research in Peoria, IL, where he worked under the tutelage of Dr. Edward Emken. Dr. Byrdwell worked on the analysis of triacylglycerols using HPLC with atmospheric pressure chemical ionization mass spectrometry (APCI-MS). They produced the first report of the use of HPLC/APCI-MS for triacylglycerol analysis. Dr. Byrdwell obtained a permanent position and stayed on at the NCAUR for 5 ½ years.

Then, Dr. Byrdwell was drawn by the sun and sand down to south Florida, where he took a position as an Assistant Professor at Florida Atlantic University. There, he continued to pursue lipid analysis, and published the first of several reports that demonstrated the use of dual mass spectrometers, in parallel, each using a different ionization technique.

He re-joined ARS in 2005, and put his expertise in LC-MS for Lipid Analysis to use on the lipid soluble Vitamin D. Currently Dr. Byrdwell is working on analysis of vitamin D and other fat soluble vitamins and triacylglycerols using triple- and quadruple- parallel mass spectrometry approaches, combining the best aspects of three or four mass spectrometers employing complementary ionization methods in LCx/MSy techniques. To date, Dr. Byrdwell has published more than 40 peer-reviewed articles and 8 book chapters. A list of publications is at www.Byrdwell.com/publications.html.
