    Barzi earned her M.D. from Tehran University of Medical Sciences, then went on to earn a Master’s in Health Informatics and a Doctorate in Public Health Management and Policy Sciences from the University of Texas Health Science Center in Houston. She recently completed a fellowship in hematology and oncology at the Cleveland Clinic’s Taussig Cancer Center.

    Her research interests are the development of new cancer therapies as well as healthcare economics and metrics of healthcare quality for improving patient care. Dr. Barzi has proposed a phase II study to investigate the overall survival benefit of adding lapatinib to docetaxel in a second line setting in patients with trastuzumab-resistant, HER2-positive gastric cancer.

    “Delivery of personalized treatment to gastric cancer patients has lagged behind other diseases,” Barzi says. “My goal is to establish a second-line treatment for these patients that are HER2-positive and to better understand the mechanisms of resistance to HER2-targeted therapy, paving the way for new therapies that can overcome that resistance.”
