Dr. Ambaye’s scholarly work focuses on breast prognostic and predictive markers, IHC assay development and validation, and quality assurance. He has led and collaborated on funded studies that evaluate diagnostic concordance between whole slide imaging and light microscopy, optimize PD L1 and hormone receptor testing, and investigate biomarkers in breast and pancreatic neoplasia. His publications include original research and multi institutional efforts addressing analytic validation of predictive markers and standardized cell line controls for IHC.
An educator and mentor across the undergraduate, medical, and GME continuum, Dr. Ambaye has directed UVM’s Introduction to Human Diseases course for many years and developed comprehensive IHC seminars for residents and fellows. He has received multiple teaching award nominations and contributes nationally through service to the College of American Pathologists (CAP)—including leadership roles in the CAP IHC Committee and House of Delegates—and internationally through educational outreach and capacity building in Ethiopia.
