Research and Clinical Interests

My goal is to develop a better understanding of the critical elements for histological classification of primary CNS neoplasms with specific emphasis on pediatric brain tumors, their distinctive subtypes and prognostic markers for each subtype. Our observations contributed to the understanding of biological behavior and molecular features in some tumors such as pilomyxoid astrocytomas. My laboratory actively collaborates with many colleagues from the Brain Tumor Research Center, UCSF, and scientists from other institutions such as Johns Hopkins University, Stanford University, and the Mayo Clinic to better define entities, and novel prognostic markers. I participate in the activities of California Childhood Brain Tumor Consortium, Children’s Oncology Group and WHO Classification of Tumours of the Nervous System. I take an active role in our professional organizations as the Vice President for Professional Affairs of the American Association for Neuropathologists. I also function as a member of the test material development committee of the NBME for Step I examination.
