Director, Canon Stroke & Vascular Research Center

Associate Professor of Neurosurgery

Associate Professor of Radiology 

Dr. Adnan Siddiqui, MD, PhD, is a Professor of Neurosurgery and Radiology who joined UBNS in January 2007. He completed fellowship training in Interventional Neuroradiology, Cerebrovascular Surgery and Neurocritical Care from Thomas Jefferson University in Philadelphia.  Dr. Siddiqui has special interest and expertise in the performance of complementary microsurgical, radiosurgical and endovascular techniques for the comprehensive management of cerebrovascular conditions. This spectrum of disease includes aneurysms and arteriovenous malformations, as well as dural, cavernous and spinal fistulae. 

Assistant Professor of Neurosurgery

Dr. Jason Davies is an Assistant Professor of Neurosurgery and Biomedical Informatics

at the State University of New York (SUNY) at Buffalo, where he joined the department in 2016. His active research interests focus on using bioinformatics tools to advance personalized

medicine. He is working to develop of bioinformatics tools to improve the quantity and quality of data available for medical research, and to lower barriers to entry for all clinicians to contribute to medical knowledge. Furthermore, he is working to bring to bear more advanced machine learning and data analytic methods to

better understand the insights contained within these rich data resources. 

Assistant Professor of Neurosurgery

Dr. Snyder joined UBNS in 2011 after completing his fellowship training in endovascular

neurosurgery with UB Neurosurgery and spent 6 months as a research fellow at the Barrow Neurological Institute under Dr. Robert Spetzler. He completed his neurosurgical residency at UB and received his PhD in biophysics under the guidance of Dr. Frederick Sachs specializing in mechanoelectric transduction of cellular membranes. Active research interests include use of CT Perfusion (CTP) for acute stroke management, application of perfusion imaging to on table angiography, glasses free 3D imaging in both the operating room and endovascular suite, as well as basic science research on the role of mechanosensitive ion channels in both in aneurysm formation and vasospasm.

Co-Director, Imaging Division 

SUNY Distinguished Professor; 

Director, Division of Radiation Physics

Education and research in medical imaging have been Dr. Rudin’s main interests during his rich career at CSVRC.  His research pursuits have primarily involved the development of improved medical imaging methods to increase resolution and lower dose. His projects to develop high spatial resolution detectors that allow for better guidance and treatments during minimally invasive endovascular procedures have culminated in systems that are now in clinics world-wide. Current work is focused on high speed image development.

Department of Radiology

A specialist in radiological imaging physics and radiation safety, Dr. Bednarek is board certified in Diagnostic, Therapeutic and Medical Nuclear Physics by the American Board of Radiology. His research focus is on region-of-interest imaging including development and evaluation of limited-field-of-view, high resolution and, recently, high-speed imaging detectors with specific application to neuroimaging. Recent work has focused on methods for determination of patient and staff radiation dose and development of a real-time dose-tracking system (DTS) for interventional fluoroscopic procedures that culminated in a licensed, FDA approved product with worldwide distribution.

Co-Director, Engineering Division 

Assistant Professor, Biomedical Engineering 

 Within the scientific community, Dr. Ionita has become deeply involved with the effort to implement the new advances of 3D printing into a clinical setting.  Using his experience in CT reconstruction algorithms and 3D data analysis, he has developed a complex 3D printed vascular patient specific phantom, based on 3D imaging.  Current work includes development of a DICOM standard associated with the workflow and manufacturing of 3D printed medical objects,  developing implantable devices, and improving printed models by creating digital structures capable of simulating vascular tissue. 

Dr. Ying is currently a full professor of Biomedical Engineering and Electrical

Engineering at the University at Buffalo and an expert and technical leader in

the field of biomedical imaging. Her research interests include magnetic resonance imaging, compressed

sensing, image reconstruction, and machine learning.  Dr. Ying has been well recognized as one of the pioneers in compressed

sensing MRI, which has recently been approved by FDA and will be the future in

routine clinical MRI scans. More recently, she published the first paper on deep

learning for MR image reconstruction, which opened up a completely new field

in MRI. The paper has received more than 100 citations in two years.

SUNY Empire Innovation Professor of 

Dr. Zhang is currently the SUNY Empire Innovation Professor in the De-partment of Biomedical Engineering at University at Buffalo. Dr. Zhang is a pioneer and has made tremendous contributions in the development of the early ultrahigh field whole-body MR imaging instrumentation, a highly sensitive imaging tool for better delineating morphology, function, and metabolism of living systems non-invasively. He, as one of the key researchers, participated in the development of world’s first 8-Tesla (8T) whole body MR system and also the world’s first 7-Tesla (7T) whole body MR system. In the past 10 years, Dr. Zhang’s MR research has expanded to the technical development and clinical translation of hyperpolarized C-13 metabolic imaging and interventional neurovascular MR imaging.
