Dr. Weitzel conducts research in many areas of medical device development for application in patients with renal and vascular diseases. Research interests include End Stage Renal Disease, vascular access for dialysis, bioengineering, and emerging ultrasound imaging modalities including strain and elasticity imaging. Dr Weitzel’s research group and collaborators perform pre-clinical and clinical testing of new diagnostic tools applied in diverse areas impacting the health of patients with kidney diseases and kidney failure.
