Summary

I am a board certified nephrologist, epidemiologist, and clinical trialist at UC San Diego Health. My research focuses in two main areas, novel therapies chronic kidney disease mineral bone disorders (CKD-MBD), and non-invasive assessment of kidney tubule health. My team and I have evaluated a myriad of blood and urine proteins that non-invasively assess the health of kidney tubule cells, and are working to determine if these markers improve assessment of risk of future kidney disease progression and cardiovascular disease risk.
