Timothy Triche, MD, PhD

Co-Director, Center for Personalized Medicine Program (CPM)
Attending Physician
Professor of Pathology and Pediatrics (tenured), Keck School of Medicine of USC

Dr. Timothy Triche is the Co-Director for the Children’s Hospital Los Angeles (CHLA) Center for Personalized Medicine. He previously served as Chief of the CHLA Department of Pathology and Laboratory Medicine for over 20 years. Prior to joining CHLA, Dr. Triche was Head of Molecular Diagnostics in the Laboratory of Pathology at the National Cancer Institute. At CHLA, he directs a cancer genomics, biology, and nanotechnology laboratory research program. He has developed numerous biomarker profiles for cancer diagnosis, prognosis and treatment as part of the NCI’s Director’s Challenge, SPECS and TARGET initiatives. His focus is on functional characterization of non-coding RNAs in cancer and development.

He received his undergraduate degree in physics and biology from Cornell University in 1966, where he was a Cornell National Scholar, and MD and PhD degrees from Tulane University in 1971, where he was a Medical Scholar Training Program grant recipient. He received his specialty training in pathology and surgical pathology at Barnes Hospital-Washington University School of Medicine, where he also did a post-doctoral fellowship in cancer-associated lectin biochemistry. He subsequently did a further post-doctoral fellowship at the NCI, which eventuated in a tenured faculty position as Section Chief in the Laboratory of Pathology at the NCI immediately thereafter.

The overarching goal of our research is to improve the outcome for patients with cancer. To do so, we seek to better understand the underlying genetic mechanisms that drive the development of cancer, or oncogenesis. In addition, we hope to utilize this newfound knowledge to identify therapeutic targets and deliver targeted therapies to tumor cells using nanoparticle delivery therapy.
