Robin A. Felder, Ph.D.
Professor of Pathology
Associate Director of Clinical Chemistry and Toxicology

EDUCATION:

Graduate School: Georgetown University, Washington, D.C., PhD, Biochemistry
Post Doctoral Training: The National Institutes of Health (NIH), Bethesda, Maryland

CLINICAL:

Clinical chemistry; application of automation, robotics, and process improvement to clinical laboratory testing.

BASIC RESEARCH:

Pathogenesis of essential hypertension and salt sensitivity – We employ a multidimensional approach to the study of high blood pressure including the  molecular genetics,  biochemical techniques, in-vitro, and in-vivo studies in humans.    Through the use of in vivo pharmacologic experiments we have demonstrated that a defect in an intracellular enzyme results in the inability to normally excrete sodium, thus leading to elevated blood pressure. Our studies extend to  the use of human subjects in the Clinical Research Center to determine the effect of pharmacologic intervention in normal and pathologic states.

APPLIED RESEARCH:

Medical automation, robotics and process improvement to assist in efficient management of the clinical laboratory.  For a complete list of automation articles visit http://marc.med.virginia.edu.  Dr. Felder has developed a number of medical process improvement technologies and commercialized them through the UVA Patent Foundation process at UVA.
