Meet the Team

Hoag’s Precision Medicine Program brings together clinical and scientific experts in oncology, genomics, genetics, molecular pathology and genetic counseling who work together to apply precision medicine to the diagnosis, treatment, and prevention of cancer. The team gathers at multiple disease specific tumor board conferences, and a dedicated monthly Molecular Tumor Board to discuss patient cases and the integration of a precision medicine approach to assist in patients’ treatment.

Hoag's Precision Medicine Program Team is comprised of industry experts with vast knowledge in genetics, molecular biology and tumor sequencing. The Team (from left to right): Dr. Valentina Dalili, Dr. Burton Eisenberg, Dr. Michael Demeure, Dr. Sourat Darabi, Dr. David Braxton, Carol Norman, R.N., Jeanne Homer, M.S., Frances Oh, M.S., and Chelsey Weatherill, M.S.

Precision Medicine Program Director – Michael Demeure, M.D., M.B.A., F.A.C.S., F.A.C.E.

Dr. Demeure is the Program Director for Precision Medicine at Hoag Family Cancer Institute, a fellowship-trained endocrine surgeon and a past-president of the American Association of Endocrine Surgeons. He is a member of many prestigious organizations including the American Association for Cancer Research, the American Society of Clinical Oncology, the American College of Surgeons and the American Surgical Association. Dr. Demeure is an internationally recognized expert in cancer surgery and research, with particular expertise in endocrine, pancreatic and gastrointestinal cancers. Dr. Demeure is regularly recognized as one of “America’s Top Surgeons” and has been consecutively named as one of the “Best Doctors in America.” He is the author or co-author of over 100 scholarly works and has given numerous invited lectures and presentations.

Prior to joining Hoag, Dr. Demeure led an active research lab for over 20 years with the majority of his efforts centered on using genomic technologies to develop novel biomarkers, identifying new therapeutic targets, and improving treatments for endocrine and gastrointestinal cancers. Over the past three years, Dr. Demeure helped the Translational Genomics Research Institute (TGen) with the launch and direction of Ashion, a commercial clinical sequencing lab, serving as the chief medical officer, executive vice-president and general manager.

Dr. Demeure collaborates with the following specialists in the application of precision medicine to patient care:

Medical Geneticist – Valentina Dalili-Shoaie, M.D.

Molecular Pathologist – David Braxton, M.D.
Dr. Braxton is a fellowship-trained molecular pathologist and part of Hoag’s Precision Medicine Program. He is board-certified in anatomic, clinical and molecular genetic pathology and completed his medical schooling at Keck School of Medicine of USC, an anatomical pathology/clinical pathology residency at Emory University School of Medicine and fellowships at the University of Pennsylvania and University of California, Los Angeles. Dr. Braxton’s research interests include identification of new driver alterations in cancer and clinical significance of mutational and biomarker profiles. Since joining Hoag in 2016 Dr. Braxton has developed and implemented protocols resulting in over 500 patients per year receiving genomic tumor testing. He is currently developing protocols for using tumor genomic reports as a screening test for inherited predispositions to cancer (germline genetic screening program).

Executive Medical Director, Hoag Family Cancer Institute – Burton Eisenberg, M.D.

Clinical Genomics Scientist/Educator – Sourat Darabi, Ph.D., M.S.
Sourat Darabi, Ph.D., M.S. is the Clinical Genomics Scientist for the Precision Medicine Program at Hoag Family Cancer Institute where she leads initiatives that further the education and application of oncology precision medicine for Hoag physicians, clinicians, and patients. Prior to her role at Hoag, Dr. Darabi served as the Variant Scientist at Ambry Genetics and worked in research departments at community and academic medical centers. She completed her Ph.D. in Healthcare Genetics at Clemson University.

Certified Genetic Counselors – Jeanne Homer, M.S., Frances Oh, M.S. and Chelsey Weatherill, M.S.

Precision Medicine at Hoag
