Leadership Team

John Valliant, PhD, CEO and Scientific Director

John played an integral role in conceptualizing and establishing CPDC and continues to drive the growth and success of the centre’s R&D and commercialization programs. In addition to his roles at CPDC, John is an Associate Professor in the department of Chemistry and Chemical Biology, at McMaster University. He has an exceptional track record of securing funding for basic and translational research particularly as part of collaborative grants. Most recently, in partnership with the Cross Cancer Institute, John led a successful grant application to create a major training grant to educate the next generation of radiopharmaceutical scientists in Canada. He has also helped to secure funding for a prototype breast imaging camera which is being evaluated in Hamilton as part of a collaborative trial.

John is internationally recognized for his work in radiopharmaceutical chemistry, where his current research focuses on developing new radiolabeling methods and compound discovery strategies to create clinically relevant molecular imaging probes and therapeutic radiopharmaceuticals. In recognition of his work and the emergence of the CPDC, John was asked to give the plenary lecture at the 2009 Society of Nuclear Medicine meeting. He was also selected as one of Canada’s 2009 Top 40 Under 40, a distinction that recognizes his exceptional work at CPDC and McMaster University to advance molecular probe technology, improve patient care and spur on economic growth. The award also acknowledges his commitment to education and training at McMaster and within the imaging industry.

John has published more than 75 papers in refereed journals and conference proceedings, and has been invited to speak at scientific conferences and leading research centres the world over. He currently has six patents or patent applications under review.

John completed his PhD at McMaster University, followed by a post-doctoral fellowship under the joint supervision of professors Alun G. Jones (Harvard) and Alan Davison (MIT).


Christopher Leon, RPh., MBA, Executive Director

Christopher brings to the CPDC more than 18 years of experience in radiopharmaceutical compounding, manufacturing and production. Having received a pharmacy degree from Philadelphia College of Pharmacy and Science, he held positions of increasing responsibility with various radiopharmaceutical companies within the U.S. and Canada. After receiving his MBA from Lehigh University, his responsibilities changed from production and manufacturing to business development. During his career he has been instrumental in the expansion and commercialization of radiopharmaceuticals such as FDG, while decreasing the cost of operations. In his last project he led the development of a radiopharmacy and FDG manufacturing facility in Quebec.


Anne Goodbody, PhD, Executive Director, Regulatory, Clinical and Quality

Anne has extensive experience in translating scientific discovery into product development with over 20 years of research and development experience in the pharmaceutical industry. After receiving a PhD in biochemistry from the University of Cambridge (UK), she held positions of increasing responsibility in a number of biotechnology companies in Canada and the U.S. She has led the development of radiopharmaceuticals, managing teams responsible for manufacturing, clinical and regulatory affairs. She has published extensively, presented research at international conferences and is a named inventor on 15 issued patents.


Karin Stephenson, PhD, Director, Discovery

Karin leads CPDC’s chemistry group and oversees the discovery and development of new molecular imaging compounds. She brings over a decade of experience in both PET and SPECT probe technology. She received her PhD in Chemistry from McMaster University and subsequently completed two post-doctorial fellowships at the University of Pennsylvania and the Centre for Addiction and Mental Health. She has published and contributed to numerous scientific articles and has received national and international awards and scholarships for her outstanding work on the development of novel probes for both positron emission and single photon emission computed tomography. Her experience in this field will help the CPDC meet its goals to develop and commercialize new probes, bringing better tools to the clinic for imaging, diagnosis and therapy.


Travis Besanger, PhD, Executive Director, Business Development

Dr. Besanger joined the Centre in 2008 with a mandate to create quality systems for GMP radiopharmaceutical manufacturing and to lead the quality assurance, quality control teams. He later expanded his responsibilities to include process and analytical development programs. With a passion for science and business, combined with experience from his previous tenure, Dr. Besanger saw an opportunity to increase CPDC’s manufacturing capabilities to offer contract service in a field with few options. Since 2011, Dr. Besanger has been leading the CPDC business development initiative and has expanded the CPDC’s offerings to a full suite of pre-clinical, clinical, regulatory and GMP manufacturing services which have benefited the CPDC’s expanding list of clients in the US, Canada and Europe. Dr. Besanger holds a PhD in Analytical Chemistry from McMaster University and previously held positions in analytical and process development at Molecular Insight Pharmaceuticals.


Kristina Trollip, Director of Administration

Kristina joined CPDC in 2008 and is responsible for the Centre’s administrative operations. She manages several key functions including purchasing, human resources, finance, information technology, office services and communications. Her 18 years of experience in administrative roles is a great asset in facilitating the delivery of CPDC’s strategic plan, supporting the Centre’s growth and maintaining a strong, cohesive operations team.

Prior to her position at CPDC, Kristina held a range of administrative roles at McMaster University that included managing and collecting research data, assisting with grant and budget development, serving as a liaison between sponsor funding sources, developing administrative operating policies and procedures.


John Forbes, PhD, Deputy Director, Discovery

John Forbes brings to the CPDC more than 11 years of post-graduate and academic experience in cell biology and immunology, molecular biology, biochemistry and leading pre-clinical drug development studies. He leads the biological research activities of CPDC’s probe discovery and development efforts. Most recently, John was a project leader at Therapure Biopharma, focused on the design, development and management of multiple pre-clinical studies. Prior to that, he was a senior research scientist in pre-clinical research at Vasogen Incorporated. After receiving his PhD in medical genetics at the University of Alberta, John went on to complete post-doctoral work in chemistry at McGill University.


Joe McCann, PhD, Director, Radiopharmaceutical Development and Manufacturing

As Director of Radiopharmaceutical Development and Manufacturing, Joe McCann oversees Chemistry, Manufacturing and Controls (CMC) activities for new and existing products. Since joining the CPDC, Dr. McCann has directed the development, validation and technology transfer activities for several novel and generic agents including [F-18]-Fluorothymidine (FLT), [F-18]-Fluoroazomycin Arabinoside (FAZA) and [F-18]-Fluoromethylcholine (FMC), as well as directing process scale-up and validation activities for [F-18]-Fluorodeoxyglucose.

Prior to joining CPDC, Dr. McCann was a Scientist in Pharmaceutical Development at GlaxoSmithKline focused on formulation, process and analytical development activities for products spanning candidate selection to Phase III studies. He was involved in quality-by-design initiatives, playing a lead role in the development and implementation of process analytical technologies to support process understanding and control. Dr. McCann’s experience at GSK as a Project and Formulation Lead on Clinical Matrix Teams, Project Teams and Product Delivery Teams will enhance CPDC’s capability in the assessment of new molecules in the clinic.

Dr. McCann holds a PhD in Biochemistry from McMaster University and a Bachelor of Science, Honours Biochemistry Co-op, from the University of Guelph.
