Joanne (Eunhee) E. Yi, M.D.

Joanne (Eunhee) E. Yi, M.D., graduated from the College of Medicine at Seoul National University in Korea in 1982 and received board certification in anatomic pathology before coming to the U.S. in 1986. She received board certification in anatomic pathology and clinical pathology in 1992 after training in Washington Hospital Center and University of California, Irvine.

She was recruited to University of California, San Diego (UCSD) in 1992 and developed expertise in pulmonary pathology during her 14-year stay there. She also served as the curator of the Averill Liebow Pulmonary Pathology Collection, including more than 5,000 cases of glass slides and radiology films that Dr. Liebow accumulated while he served as the chairman of the UCSD pathology department.

She joined the Pulmonary Working Group in the Division of Anatomic Pathology at Mayo Clinic in Rochester, Minn., in 2006 and is a consultant and professor of laboratory medicine and pathology in the College of Medicine, Mayo Clinic. She is also a member of the Frozen Section Working Group and Heart and Lung Transplant Working Group.

Dr. Yi's area of interest encompasses both neoplastic and non-neoplastic lung diseases, with more than 100 publications in peer-reviewed journals. At UCSD, she did basic research on inflammatory and fibrosing lung diseases to explore cytokine regulations in the pathogenesis and prevention by exogenous growth factor injections, using various rodent models that she developed or modified: C.-parvum-induced granulomatous inflammation, bleomycin-induced lung disease and its prevention by keratinocyte growth factor, radiation-induced lung disease and role of TGF-beta, PDGF-BB and keratinocyte growth factor, and more.

In the past seven years at Mayo Clinic, she has worked on various biomarkers of non-small cell carcinomas, especially ALK and BRAF mutation in pulmonary Langerhans cell histiocytosis, as well as in adenocarcinomas more recently. Her current research interest on non-neoplastic diseases includes comparative morphologic assessment of pulmonary hypertension in patients with left heart disease and pulmonary veno-occlusive disease and the role of aspiration in usual interstitial pneumonia.
