Surgery Service Line Research includes faculty members, affiliated surgeons, and investigators who are involved in research studies and clinical trials. The Inova Fairfax campus is strategically located in Northern Virginia in close proximity to Washington, DC, serving and caring for a culturally rich and diverse population. This allows us to study and address critical disparities in healthcare within our community.

Our team supports the research efforts for surgical services offered at all Inova hospitals in the region, including breast, cancer, cardiac, colorectal, endocrine, gastrointestinal, general, ophthalmology, plastic, thoracic, transplant, trauma, and vascular surgery care. As the only designated and verified Level 1 trauma center in Northern Virginia, the Inova Trauma Center has dedicated research staff who especially focus on improving safety, education, and trauma patient care through research.

About the Foundation:

The Surgery Research and Education Foundation in partnership with the Inova Health Foundation helps enhance the support for our research and education efforts. The private support we receive through this foundation enables us to provide world-class surgical education to medical students, residents, nurses, and faculty which impacts the lives of our patients. The direct impact of this foundation was the expansion of the Advanced Surgical Technology and Education Center (ASTEC). Additionally, this foundation supports our research efforts which affects our community by providing the necessary infrastructure our young and seasoned researchers need to change our patient experience, treatments, and outcomes.
