    An-Chi Tien, PhD

    Assistant Professor,
    Neurobiology (602) 406-4493

    An-Chi Tien, PhD, is an assistant professor in the Department of Neurobiology at Barrow Neurological Institute. He works in the Ivy Brain Tumor Center.

    Dr. Tien’s expertise includes developmental biology and genetics, particularly applied to neuro-oncology. Dr. Tien is a member of the American Brain Tumor Association Alumni Research Network, the American Society of Clinical Oncology, and the Society for Neuro-Oncology.

    Dr. Tien earned his doctorate degree in developmental biology from the Baylor College of Medicine in Houston. He completed his postdoctoral research fellowship at University of California San Francisco’s Institute for Regenerative Medicine.

    Dr. Tien’s research focuses on establishing and optimizing pharmacodynamic tests to support clinical trials for patients with brain tumors and to better understand tumor resistance mechanisms.
