Dr. Neilan has had a long-standing clinical and research interest in the cardiovascular care of patients with cancer. Cardiovascular disease is a leading cause of death and disability among cancer survivors and cardiovascular care for patients with cancer requires a tailored approach that is unique for each patient. He is specifically interested in how we can improve on the methods for detection of the cardiac toxicity after chemotherapy and radiotherapy and to use that information to determine how we care for patients.
