About me
Robby Lyallpuri is a nephrology and hypertension nurse practitioner fellow at North Shore University Hospital. He completed his doctoral training at Columbia University School of Nursing, where he developed a passion for blood pressure regulation and kidney disease.
Prior to his advanced practice role, Robby worked as a registered nurse at Stern Family Center for Rehabilitation (Northwell Health), where he spent nearly two years caring for patients recovering from complex neurological and medical conditions. His research background spans two institutions: he completed a summer research program on lupus under Dr. Myoungsun Son at the Feinstein Institutes for Medical Research, followed by work at the Icahn School of Medicine at Mount Sinai in the laboratory of Dr. Konstantina Alexandropoulos, where his focus on autoimmune hepatitis contributed to a peer-reviewed publication.
Based in the New York metropolitan area, he is dedicated to advancing care for patients with complex renal and hypertensive conditions. Fluent in Punjabi, Hindi, and Urdu — and with a working knowledge of Mandarin — Robby brings a multicultural perspective to his practice, connecting with patients across diverse communities in their own language.
