Dr. Grand has served as clinical professor of neurosurgery for UBNS since 1992. His research interests lie in the area of endoscopic brain surgery and neurosurgical anatomy. He is the senior author of the book, Vasculature of the Brain and Cranial Base: Variations in Clinical Anatomy.

He has lectured widely on endoscopic neurosurgery and minimally invasive brain surgery in the United States, Germany and Finland. Additionally, Dr. Grand conducts an annual brain endoscopy seminar for residents and neurosurgeons in Buffalo, as well as an annual neurosurgical forum in Ponte Vedra Beach, Florida.

He is member of the North American Skull Base Society, the American Association of Neurological Surgeons (AANS), the American Medical Association (AMA), and the Congress of Neurological Surgeons (CNS). He is also on the advisory board of the journal, Minimally Invasive Neurosurgery.
