As a clinician/educator in the Division of Nephrology, my clinical activities are mainly focused on the care of patients with end-stage renal disease. I am a Medical Director of a dialysis unit in Henderson, NC which cares for approximately 155 patients. I am a rounding nephrologist at a dialysis unit in Warrenton, NC where I and my partners care for roughly 35 patients. When at Duke, my clinical activities are focused on inpatient care of maintenance dialysis patients and general consultative nephrology. In addition, I see outpatients with a variety of nephrologic problems (chronic kidney disease, proteinuria, and hypertension) in the Private Diagnostic Clinic. I mentor fellows in this outpatient clinic.  In recent years, I have been an attending physician for a Duke General Medicine inpatient service six weeks per year.

In regard to educational activities, I am a lecturer for Normal Body, the physiology course for first-year medical students.  I am the course director for Fluids and Electrolytes, an elective course for third- and fourth-year medical students.  I give several lectures per year for our Lecture Series for Renal Fellows.

Key words: end-stage renal disease, vascular access for hemodialysis, renal osteodystrophy, consultative Nephrology.
