Michael Roh

Dr. Michael Roh is a Professor in the Department of Laboratory Medicine and Pathology at Mayo Clinic in Rochester, Minnesota, specializing in Anatomic Pathology. He holds both MD and PhD degrees in Biological Chemistry from the University of Michigan Medical School (2004) and completed his pathology training at Harvard Medical School's Brigham and Women's Hospital. Dr. Roh maintains active professional roles as a Lead Reviewer for the United States and Canadian Academy of Pathology, Member of the International Society of Gynecologic Pathologists, and contributor to multiple pathology organizations.

Dr. Roh's research interests focus on cytopathology, particularly effusion cytology, fine-needle aspiration diagnostics, and molecular testing applications. His work extensively covers thyroid pathology, gynecologic pathology, and the application of immunohistochemistry in diagnostic cytology. He has made significant contributions to understanding the utility of biomarkers like GATA3, PAX8, PAX2, TTF-1, and Napsin-A in cancer diagnostics.

His publication record shows a clear progression from foundational work in cell polarity and tight junctions during his PhD studies to clinical applications in cytopathology. Recent publications (2019-2024) demonstrate a strong focus on molecular applications in cytology, including the utilization of cytologic samples for ancillary molecular testing and next-generation sequencing applications. His research consistently bridges traditional cytology with modern molecular diagnostics.

Dr. Roh has been actively involved in developing professional guidelines, notably co-authoring the Papanicolaou Society of Cytopathology consensus recommendations for respiratory cytology. He serves as a reviewer for major pathology journals and organizations and has contributed to numerous multi-institutional studies that have shaped current diagnostic practices in cytopathology. His work on gender disparities in referral for pleural effusion care highlights his interest in healthcare equity issues within pathology practice.

Dr. Roh leads the Cytopathology Research Laboratory at Mayo Clinic, where his team focuses on optimizing diagnostic approaches for challenging cytology specimens and developing new applications for molecular testing in limited cytology samples. His laboratory work has direct clinical applications that improve diagnostic accuracy and patient care pathways.
