Professor Wim Oyen is Professor of Nuclear Medicine and Molecular Imaging and Team Leader in Translational Molecular Imaging at The Institute of Cancer Research, and Consultant in Nuclear Medicine and Head of the Department of Nuclear Medicine at The Royal Marsden NHS Foundation Trust. He leads a programme to translate new radiopharmaceuticals developed at the ICR into clinical studies at The Royal Marsden and to introduce novel molecular imaging approaches for staging, treatment selection and monitoring of treatment response, as a means of optimising therapy for the individual cancer patient. 

He is author on more than 600 articles in scientific journals, including Lancet Oncology, Nature Reviews Clinical Oncology and The Journal of Clinical Oncology, and more than 100 papers in The Journal of Nuclear Medicine. The scientific work of his group was awarded with The Marie Curie Award of the European Association of Nuclear Medicine in 1994 and in 2011. He was awarded with honorary membership of the European Society for Radiotherapy and Oncology in 2009. 

Currently, he sits on the Board of the European Cancer Organisation (ECCO) and has served on the Board of the European Association of Nuclear Medicine (EANM) as the Congress Chair 2014-2016. As of January 2017, Professor Oyen is EANM President-elect and will start the two-year presidential term in 2019. He is actively involved in the European Organisation for Research and Treatment of Cancer (EORTC). He serves as Associate Editor of The Journal of Nuclear Medicine and is a member of the editorial board of the European Journal of Nuclear Medicine and Molecular Imaging and other international imaging journals.

Dr. Michael Morris

Dr. Morris is a clinical investigator with the Genitourinary Oncology Service at Memorial Sloan Kettering Cancer Center, which he is Section Head of Prostate Cancer and is the Clinical Director. He earned his medical degree from the Mount Sinai School of Medicine in New York, performed his internship and residency in internal medicine at New YorkPresbyterian/Columbia University Medical Center, and his medical oncology fellowship at Memorial Sloan Kettering Cancer Center, where he was Chief Fellow. Since then, he has been on faculty at MSKCC in the GU Oncology Service, with a research focus on developing
novel therapies and imaging biomarkers for metastatic prostate cancer.
Dr. Morris has been the PI of numerous clinical trials, but has a particular research focus on targeted therapy for prostate cancer, in particular those that bridge the fields of medical oncology and nuclear medicine. From a therapeutic standpoint, he has had a particular focus on radioimmunotherapy and other radio-conjugates, bone directed therapy, and tumor-targeted therapies. He also has a keen research interest in developing novel imaging technologies for metastatic prostate cancer, especially in regards to testing them as validated biomarkers. He has been a co-developer of the Prostate Cancer Working Group 2 and 3 Consensus Criteria, and novel prostate-specific imaging technologies such as FDHT PET imaging and PSMA-directed PET imaging.
In addition, he is the Medical Director of the Department of Defense/PCF Prostate Cancer Clinical Consortium, and Chairs the GU Committee of the NCI cooperative group, Alliance for Oncology Trials in Oncology.

Dr. Eugene Leung

Dr. Leung received his MD from the University of Ottawa. After completing residency dedicated to Nuclear Medicine at the University of Western Ontario, he received specialist certification from the Royal College of Physicians and Surgeons of Canada, the American Board of Nuclear Medicine, and the Certification Board of Nuclear Cardiology. Following a fellowship in radioisotope therapy, Dr. Leung joined as a full-time member of the Division of Nuclear Medicine at The Ottawa Hospital in 2007 and practices broadly in all aspects of Nuclear Medicine, including cardiac, PET, bone densitometry, and therapy. He is an assistant professor at the University of Ottawa, Clinical Investigator at the Ottawa Hospital Research Institute and has served as Director of Patient Quality and Safety in his Division.

 Dr. Leung is enthusiastically committed to the rapidly evolving field of functional imaging and theranostics. He enjoys broadening the understanding of this dynamic specialty to the public, medical students, residents, technologists, and colleagues alike through education, collaboration and research. He has lectured abroad and published on specific clinical interests such as PET imaging of cardiac sarcoidosis. He is a board examiner for Canadian diplomates through the Royal College and at the Kuwait Institute for Medical Specialization through the Royal College outreach program. He collaborates closely with multiple specialties to share his expertise in radioisotope therapy, co-chairs of the TOH Thyroid tumor board, and has directed research studies and transitioned to clinical practice the treatment of bone metastases using radium-223.
