His research has focused on the epidemiology of acute kidney injury (AKI) including temporal population trends, cardiovascular sequelae, and kidney function decline after AKI. He has received NIH research funding since his nephrology fellowship at UCSF, during which he also obtained a Master’s degree in epidemiology and biostatistics. He currently works with data from the NIDDK-sponsored cohorts, the Chronic Renal Insufficiency Cohort (CRIC) and ASsessment, Serial Evaluation, and Subsequent Sequelae in Acute Kidney Injury (ASSESS AKI). He is also experienced in working with big data from the National (Nationwide) Inpatient Sample—the largest publicly-available all-payer inpatient database in the U.S., and from Kaiser Permanente—one of the largest integrated healthcare organizations in the country. Dr. Hsu is a practicing nephrologist at UCSF Medical Center.
