Antoni Ribas, MD, PhD

Dr. Antoni Ribas is a physician-scientist conducting laboratory and clinical research focused in malignant melanoma. His research includes:

• laboratory and clinical translational research in adoptive cell transfer therapy with T-cell receptor (TCR) engineered lymphocytes
• understanding the antitumor activity of PD-1-blocking antibodies
• the laboratory and clinical testing of novel targeted therapies blocking oncogenic events in melanoma and their use as immune sensitizers
• studies of primary and acquired resistance to melanoma therapies.
