A major milestone for Dr. Rosalind Lai, our department, and the future of research.

Dr. Lai has been selected as a CTSI K Scholar through the University at Buffalo Clinical and Translational Science Institute’s Mentored Career Development Award Program.

This prestigious program supports promising physician-scientists as they advance innovative research that improves patient care.

Dr. Lai’s work will focus on s*x differences in intracranial aneurysm formation and rupture, an area that could help unlock new insights into why aneurysms develop and how we can better prevent and treat them.

"Women are affected by many inflammatory diseases more often than men. Hormones explain part of this difference, but not all of it. We now believe genes on the X chromosome may play an important role, and these same mechanisms may also contribute to the inflammation seen in brain aneurysms." - Dr. Lai

Please join us in congratulating Dr. Lai on this exciting achievement.

Honored to welcome Michael Lim, MD, Chair of Neurosurgery at Stanford University, as our Visiting Professor today.

Dr. Lim delivered an exceptional lecture on glioblastoma research and immune checkpoint pathways, inspiring our entire team.

Beyond the science, his message was clear: the future of our field depends on clinician-scientists who are willing to ask bold questions and move discovery from bench to bedside.

Meet Dr. Hanna N. Algattas!

Dr. Algattas joined UBNS in 2023, specializing in complex open and endoscopic skull base and pituitary surgery, neuro-oncology, and minimally invasive cranial procedures—with additional expertise in neurotrauma, degenerative spine disease, and traumatic brain and spinal cord injury.

A Colgate University graduate in Cellular Neuroscience, he earned his medical degree from the University of Rochester Medical Center before completing his neurosurgery residency at the University of Pittsburgh Medical Center.

He then pursued advanced fellowship training in open and endoscopic skull base surgery under Dr. Paul Gardner at UPMC, a world leader in expanded endonasal approaches for skull base tumors.

He also completed the nation’s first Sports Neurosurgery Fellowship at UPMC and was honored with the inaugural Aequanimitas Award for his humility, compassion, and dedication to patient care.

Dr. Algattas sees patients and performs surgery at Erie County Medical Center and is proud to serve Western New York as a native of Syracuse.

On World Cancer Day, we’re spotlighting a tool that has changed what brain tumor treatment can look like.

Gamma Knife is available at Atlas Ambulatory Neurosurgery Center (ANSC™), located just behind our Williamsville office. It's a highly precise form of radiation that can treat certain brain & spine tumors without making an incision.

Using hundreds of focused beams of radiation that converge on a single target, Gamma Knife can treat tumors while sparing surrounding healthy brain tissue.

Treatment is outpatient and carefully planned with MRI and CT imaging, delivered by a multidisciplinary team of neurosurgeons, radiation oncologists, and neuroradiologists.

Gamma Knife may be part of care for tumors such as:
🧠 Metastatic brain tumors
🧠 Gliomas
🧠 Meningiomas
🧠 Pituitary tumors
🧠 Craniopharyngiomas
🧠 Skull base tumors

Brain tumor care is never one-size-fits-all. Technologies like Gamma Knife expand options, reduce risk, and help more patients access advanced treatment close to home.

UB Neurosurgery and the Atlas Ambulatory Neurosurgery Center (ANSC™) are advancing brain health research by applying artificial intelligence to better understand intracranial aneurysm risk.

In 2025, UBNS and research partners were awarded a first-of-its-kind grant to launch an AI-driven, multi-omics initiative focused on anticipating aneurysm rupture risk and supporting earlier intervention.
