Rebecca McClure, M.D., FCAP

Pathologist, Health Sciences North
Scientist, Health Sciences North Research Institute
Associate Professor, Northern Ontario School of Medicine

Dr. McClure attended the University of Toronto where she received her B.Sc. in Biology in 1989, and her M.Sc. in Medical Biophysics in 1991.  She stayed in Toronto for her medical training, and received her MD degree in 1994. She then relocated to the Mayo Clinic in Rochester, Minnesota where she completed residencies in Anatomic and Clinical Pathology followed by fellowships in Surgical Pathology and Hematopathology. In 2002, she joined the staff at Mayo Clinic as a pathologist in the Department of Laboratory Medicine and Pathology, where she has practiced for over 10 years.  During her time at Mayo, Dr. McClure maintained a busy, international clinical pathology practice and was active in teaching medical students, residents, fellows and graduate students through the Mayo Medical School, where she was an associate professor. She also created and directed the clinic’s Molecular Hematology Laboratory, a job that included developing and implementing the current broad menu of clinical tests that this laboratory performs on specimens from all over the world.

Research Interests

Dr. McClure’s main research interest is understanding the genetics underlying leukemias and lymphomas. She spent much of her time at Mayo Clinic in the area of translational research, which involves dealing with the difficult, practical issues of transferring basic research findings into orderable clinical tests. In her capacity as the director of a large molecular testing laboratory, she was an early adopter of high-throughput sequencing technology for clinical test development. This powerful, new technology is rapidly changing the way medicine is practiced, as it allows physicians to rapidly, and cost-effectively, obtain large amounts of genetic information that has not been available in the past. Because abnormal genetic processes are responsible for a wide variety of disorders including cancers, inherited disorders and infectious diseases, the new technology has many applications in both the clinical setting and in research laboratories studying the genetics of these diseases.
