  • My research focuses on the epidemiology of aging with a specific interest patients with end stage kidney disease. In particular, I seek to better understanding how novel metrics of aging like frailty and cognitive function can improve risk prediction in kidney transplant recipients and patients undergoing hemodialysis. Additionally, I am conducting a 2-by-2 factorial RCT to identify interventions to preserve cognitive function among patients initiating hemodialysis. Finally, I study the impact of medications on age-related outcomes among patients with end-stage kidney disease using national registry data linked to Medicare claims.
  • frailty
  • cognitive function
  • end-stage kidney disease
  • pharmacoepidemiology

These five publications represent my diverse interest including pharmacoepidemiology, the epidemiology of aging and renal epidemiology.
