I have helped to describe the association between bisphosphonate therapy and adynamic bone disease in CKD patients, by using dynamic bone labeling and bone histology. With my colleagues at MSBI, I have described the inflammation evident in ESRD patients with various types of hemodialysis access. As a co-investigator in an industry funded clinical trial [Multi-Center Study of the Effect of Sevelamer Carbonate on Metabolic/Inflammatory/Reactive Oxygen Species (ROS) in Diabetes with Nephropathy, the AGELESS study] at MSBI and Mount Sinai, I helped recruit study subjects and am involved in the current publication of our findings. I have also guided the comprehensive survey of the impact of Hurricane Sandy on hemodialysis patients in NYC; and will soon publish our findings. As the training program director and division chief (interim) for Nephrology & Hypertension at MSBI I will be responsible for promoting scholarly activity and research among all fellows and faculty.
