Accepting new patients

Professional Summary:

I provide clinical care for a diverse group of patients with kidney disease. My research and primary clinical interest are people who have glomerular diseases that cause nephrotic syndrome, nephritic syndrome, or arise from systemic vasculitis. I am also happy to see patients with CKD of unclear cause, with the aim that I might find a reversible cause of kidney disease to prevent the need for dialysis, or delay dialysis as long as possible.
In addition, I provide care for patients with malignant hypertension, renal artery stenosis, recurrent kidney stones, genetic kidney diseases such as polycystic kidney disease, rare kidney diseases such as idiopathic retroperitoneal fibrosis, and disorders of electrolytes or acid-base status.
I have received funding from the NIH, the American Heart Association and the NephCure foundation to study the basic science of glomerular disease. This work started in cultured cells and transgenic mice, then evolved to study patients with rare mutations in APOL1 in India, and then clinical studies of Nephrotic and Nephritic Syndrome as part of the NEPTUNE and CureGN consortium.
Lastly, I provide care to patients on hemodialysis and peritoneal dialysis, with a goal of making the quality of life as good as possible while undergoing dialysis. Among dialysis patients, I have been involved with clinical studies of uremic itching, which involves opiod and capsaicin pathways instead of histamine.
As a member of the Jacobs School faculty, my goals are to remain on the forefront of clinical and translational care to provide the best care for my patients with kidney disease, and to share what I have learned over the years with medical students, resident doctors, nephrology fellows, students in NP or PA training, and more. For my teaching, I have received awards from internal medicine residents and nephrology fellows at the University of Pennsylvania, Temple University and the University of Pittsburgh.
I enjoy discussing complex kidney disease topics at all levels of medical expertise, including “lunch and learn” lectures to patients and families with nephrotic syndrome, talks with colleagues in primary care, or colleagues from Urology, cardiology and critical care who have shared interests.
