Research Interests

Dr. Thomson conducts research into the autoregulation of renal function with particular emphasis on glomerular hemodynamics and on tubuloglomerular feedback from the macula densa to the glomerular microvasculature in the control of glomerular filtration. In order to study the operational behavior of this tubuloglomerular feedback system, we have implemented methods for measuring flow in unobstructed free-flowing single rat nephrons in micropuncture experiments and for quantifying the efficiency of the tubuloglomerular feedback response when flow is perturbed. Projects are underway to elucidate the basic physiologic mechanism of tubuloglomerular feedback and to examine the role of altered proximal tubular function as a cause of glomerular hyperfiltration in experimental diabetes. This work employs a variety of biomedical research methods as adjuncts to micropuncture. But the lab remains centered around renal micropuncture, which requires Dr. Thomson to perform most experiments himself. This research is funded by an RO1 from the National Institutes of Health and a Merit Review grant from the VA Research Service.

Clinical Interests

Dr. Thomson's nephrology practice includes: ICU nephrology (acute dialysis and CRRT in the critically ill), transplant nephrology, general nephrology, hypertension, clinical fluid-electrolyte and acid-base physiology and apheresis.
