In my role at AstraZeneca, I lead our Discovery Team and am focused on Immuno-Oncology and antibody drug conjugates – from novel target identification and validation to clinical candidate selection. This includes preclinical predictive models to identify patients who have a higher likelihood of benefitting from immuno-oncology treatments, giving us the best chance of finding the most efficient routes to effective medicines.

A large piece of our research in immuno-oncology is on the possibility of living drugs – oncolytic viruses and cell therapies – to amplify the body’s own ability to recognize and attack tumors, destroying the cancer cells and, potentially, achieving cure.

I am a clinical immunologist and physician-scientist, and in my training, specialized in managing patients with immunodeficiency. My research has focused on translational immunology, which includes cancer immunology and immunotherapy. My early work related to human viral immunity and restoring anti-viral immune responses through cellular immunotherapy. Through my research, I developed a strong interest in tumor neoantigens – believed to play a dominant role in the immune system’s response to cancer – and have contributed toward the discovery of a novel class of tumor antigens.

I also serve as an Associate Professor of Medicine at Harvard Medical School and Massachusetts General Hospital Cancer Center.

I have authored nearly 50 peer-reviewed papers, co-founded six biotechnology companies, and have generated 20 patents. I lecture extensively on cancer immunology and immunotherapy at conferences and seminars, and am a member of several scientific and medical societies including the Broad Institute, American Association for Cancer Research, American Association for Hematology and the British Society for Immunology, and serve on the UK Academy of Medical Sciences Mentoring committee.

After earning a bachelor’s degree in immunology and medical degree from the University of Edinburgh, I earned a doctorate from the University of Birmingham (UK) in Immunology/Immunotherapy, and completed postdoctoral training at the University of Birmingham and the University of Virginia.

Vice President, Discovery, Oncology R&D


Associate Professor of Medicine at Harvard Medical School and Massachusetts General Hospital Cancer Center. Founded Cobbold Lab at MGH Center for Cancer Immunology, which was the first to demonstrate immunity against cancer-specific phosphopeptide antigens is present in healthy individuals and patients with cancer; the first to discover major histocompatibility complex (MHC) class-I displayed N-Acetylglucosamine and methylarginine peptide neoantigens and demonstrated these are also targets of immunity in humans; and developed three novel antibody engineering approaches to redirect T-cells against tumors with high specificity (APEC, TEAC and ATTAC)


Co-founded five biotechnology companies over eight years (SeraScience, PhosImmune, Revitope Oncology, Gritstone Oncology and GigaMune)


Reader in Translational Immunology, Medical Research Council (MRC) Centre for Immune Regulation, University of Birmingham (UK)
