About Alfonso Santos

I am a nephrologist and associate professor of medicine in the division of nephrology, hypertension and renal transplantation at the University of Florida College of Medicine. My clinical interests, include screening and evaluation of kidney transplant candidates, medical complications of kidney transplantation and the outcomes of combined kidney and other solid organ transplants, while my academic and research interests, include patient selection, assessment in kidney transplantation and the clinical impact of blood pressure medications in kidney transplant recipients.

I attended medical school at the University of Santo Tomas in the Philippines and completed an internal medicine residency at New York Medical College, where I also served as chief medical resident. I then went on to complete a nephrology fellowship at Georgetown University Medical Center and a fellowship in transplant nephrology at UF.

Outside of practice, I have presented oral abstracts and chaired a scientific session at the American Transplant Congress (ATC). I have also reviewed scientific abstracts for ATC meetings and papers submitted to transplant journals.
