Research Summary:
Dr. Harris has a national reputation for her work in the field of education, having served on the ACME Surgery Review Committee, the Vascular Surgery Milestone Project and is the past President for the Association of Program Directors in Vascular Surgery and Eastern Vascular Society. Her clinical interests include peripheral arterial disease, venous occlusive disease, dialysis access, thoracic outlet syndrome, aneurysmal disease and carotid disease. As a vascular surgeon, I am dedicated to treating and helping my patients manage conditions of the circulatory system, including diseases of the arteries, veins and lymph vessels and blood disorders that affect circulation. My patients can feel secure knowing I’m prepared to deliver the most advanced treatments available — including minimally invasive endovascular interventions, open vascular procedures and hybrid surgery techniques that combine open surgical and endovascular approaches. Vascular disease tends to be a lifelong problem; therefore, I aim to help my patients modify their lifestyles so that they experience as few vascular difficulties as possible throughout their lives. I have decades of experience researching venous disease, cerebrovascular disease, aneurysms, peripheral arterial disease (PAD) and thoracic outlet syndrome. I am committed to conducting outcomes-based research for conditions including PAD and aneurisms because my goal is to increase knowledge about the intermediate and long-term results of endovascular and vascular practices and interventions. While immediate results are important, long-term outcomes are even more important for vascular disease, as we cannot cure the conditions, but we can treat them. I work toward learning which treatments are most effective based on patients’ end results. As program director for both the vascular surgery residency and fellowship, I train the next generation of vascular surgeons to be preeminent members of the vascular surgical community. I believe that the better I prepare my medical students, residents and fellows, the more opportunities they have to positively affect a greater number of patients. My teaching covers all aspects of vascular disease; I teach trainees in clinics and the hospital setting and during angiographic procedures and open surgery. I strive to help professionals and trainees in my field stay abreast of emerging scientific research and clinical applications. That’s why I’ve co-directed and lead symposia for the Gates Vascular Institute (GVI) and Western New York Vascular Society — conferences enabling discussion about updates in cardiac, vascular and neuroendovascular medicine. It’s also why I am an adviser for the Vascular and Endovascular Surgery Interest Group, which provides faculty mentoring and support to medical students considering surgical fields. Further, teaching trainees is such an important part of my work that I became a certified educator through the Royal College of Physicians, an organization that has helped me enhance my teaching methods and learn educational techniques to help my mentees excel.

Specialty/Research Focus:
Surgery - Vascular; Surgery - Endovascular

Research Summary:
Clinical expertise: Endovascular & open surgical treatment of Peripheral arterial disease, Abdominal aortic aneurysms (AAA), Thoracic aneurysms & dissections, Carotid disease & Venous disease and Dialysis access surgery Vascular surgery has seen great advancement in the last two decades with introduction of minimally invasive endovascular techniques and devices. Vascular surgeons are not only required to stay up-to-date with the newest technologies, but also maintain the highest standards in traditional open surgery. I aim to provide comprehensive care to patients suffering from vascular diseases, including open surgical and minimally invasive treatment of peripheral arterial disease, venous disease, carotid disease, hemodialysis access, abdominal aortic aneurysm (AAA) and thoracic aortic aneurysm at Gates Vascular Institute (GVI)/Buffalo General Hospital and Erie County Medical Center (ECMC). I am also involved in the care of trauma patients suffering from vascular injuries at ECMC. I also have research interests in various aspects of vascular diseases including peripheral arterial disease and aortic aneurysm disease. Peripheral arterial disease has been my main focus and I have been involved in various studies investigating novel diagnostic and treatment modalities and their impact on our patients. I believe that technology can help us improve patient care but it should be rigorously tested before it is offered to our patients. Education is an important part of my practice and I train medical students and residents to take care of vascular patients. Some of these trainees will become vascular surgeons, ensuring provision of care to vascular patients in the future.
