Jonathan Heeney is Head of The Laboratory of Viral Zoonotics. Research focuses on cross species transmissions of viruses, and the co-evolution of viruses and their hosts including the evolution of immune mechanisms of disease protection in naturally infected but disease resistant species. Not only has this interest led to the discovery of a number of new viruses, but also genetic comparison of host and viral sequences from the same individual and sample have provided powerful genetic tools to solve some of nature's intriguing mysteries. Currently this laboratory applies these molecular technologies to address important questions concerning zoonotic infections of importance to both veterinary and human health.
