His research interests are focused on brain tumors, specifically glioblastoma in the aging population, and immunotherapies for gliomas. He recently published in Nature Medicine and Nature Cancer on potential predictors of response to PD-1 inhibitors in glioblastomas and is expanding such analysis to other gliomas. He has filed two patent applications on potential predictive biomarkers for response to PD-1 inhibitors in glioblastomas. He has been the principal investigator of multiple clinical trials and has led national studies in gliomas and glioblastomas.
