I have 30 years of experience, and specialize in the field of nephrology with specific knowledge in the areas of diabetic nephropathy, hemodialysis and peritoneal dialysis. I have published on such topics as toxic nephropathy, hemodialysis and peritoneal dialysis. I have testified on lithium toxicity. It has tracked the evolution of nephrology from the old cardio-renal divisions to the full blown specialty of today, with the incredible impact of the only really successful artificial organ. The medical, social, economic, and ethical consequences of that are still unfolding.
