Lerner Research Institute,
9500 Euclid Avenue, Cleveland, Ohio 44195
Timothy Chan, MD, PhD, a renowned immuno-oncology and cancer genomics expert, leads the Center for Immunotherapy and Precision Immuno-Oncology, which brings together multidisciplinary experts from across the Cleveland Clinic enterprise to advance research and treatment related to the rapidly growing field of immuno-oncology.
Dr. Chan also collaborates with experts in the Center for Global and Emerging Pathogens Research, which is focused on broadening understanding of immunology and microbial pathogenesis with the goal of improving treatment for a variety of diseases, including virus-induced cancers.
He is an internationally recognized expert in precision immuno-oncology and a pioneer in using genomics to determine which patients will respond best to certain types of immunotherapies. He has published over 200 articles in peer-reviewed journals, made landmark discoveries in his field and received numerous awards, including the National Cancer Institute Outstanding Investigator Award in 2018.
Dr. Chan earned his MD and PhD in genetics from Johns Hopkins University, where he also completed a residency in radiation oncology and a postdoctoral fellowship in the division of tumor biology. He is board certified in radiation oncology and is an elected member of the Association of American Physicians.
The focus of the Chan laboratory is to understand the genomic basis of tumor development and treatment response. We use both large-scale genomic analyses and functional dissection to determine what drives oncogenesis. From this information, we seek to develop improved diagnostic and therapeutic modalities for human cancers.

Cleveland Clinic Receives $7.9 Million Grant from NIH to Form Radiation Oncology-Biology Integration Network (ROBIN)
Precision cancer medicine is the goal of a new multidisciplinary study, led by Dr. Tim Chan, examining radiation therapy combined with targeted therapy
Dr. Tim Chan demonstrated that pathogenic POLE/POLD1 mutations lead to improved response to immune checkpoint blockade therapy.
Dr. Chan will serve as the core investigator at Cleveland Clinic, one of four institutions working together as part of this collaborative study funded through Aligning Science Across Parkinson’s.
