Brad Astor, PhD, MPH

  • Associate Professor
  • Department of Population Health Sciences
  • Department of Medicine


Dr. Astor's research covers multiple aspects of kidney disease, including chronic kidney disease (CKD), end-stage kidney disease (ESKD), and kidney transplantation. He has a special interest in biomarkers of kidney function and identifying risk factors for relevant outcomes, including CKD progression, ESKD, and cardiovascular disease (CVD). He also studies risk factors for outcomes in kidney transplant recipients, including infection, rejection, malignancy, CVD and graft failure. Another specific interest is studying outcomes of vascular access in patients on chronic hemodialysis. He has conducted research in these areas in the general population (e.g., Atherosclerosis Risk in Communities [ARIC] Study), in clinical trials (African American Study of Kidney Disease and Hypertension [AASK]) and observational studies of dialysis patients (Choices for Healthy Outcomes in Caring for ESRD [CHOICE]) and transplant recipients (Wisconsin Allograft Recipient Database [WisARD], APOL1 Long-term Kidney Transplantation Outcomes Network [APOLLO]).
