Byram W. Bridle

Assistant Professor   |   PhD


          I am a viral immunologist who is passionate about improving life through two avenues of research. First, my research team is dedicated to designing and optimizing novel biotherapies for the treatment of cancers. Our goal is to harness the natural power of a patient's immune system to eliminate their own cancer cells. This represents the ultimate personalized therapy and holds the potential to treat cancers more effectively, safely, and at lower cost than current options. We also work on discovering mechanisms underlying cytokine responses to viruses and other inflammatory stimuli and how these differ between males and females. This has implications for the treatment of infectious diseases and understanding sex biases in the incidence of inflammation-mediated disorders. Mentoring the next generation of Canadian scientists is a responsibility that I take very seriously. I also count it a privilege to teach students in the Doctor of Veterinary Medicine, graduate and undergraduate programs at the University of Guelph. 

Research Interests

          My research program has two arms. One is to develop novel, highly targeted biotherapies for the treatment of cancers. In an effort to kill malignant cells with minimal bystander damage to normal tissues, two approaches are combined: 1. cancer immunotherapy that directs the power of a patient’s immune system against their own tumour(s) and, 2. oncolytic virotherapy, which utilizes viruses that replicate in and kill only cancerous cells. The exquisite specificity, systemic targeting capability and short treatment windows of these therapies hold promise that cancer patients might be effectively treated with reduced side effects and at minimal cost. The goal is to translate the most promising iterations of these therapies into clinical trials in companion animals as a stepping stone towards testing in human patients. A second emphasis of the lab is the study of host responses to viruses. Specifically, efforts are being invested into understanding the mechanisms underlying virus-induced cytokine storms. We have identified a critical role of signaling through the type I interferon receptor in the negative regulation of an extensive network of cytokines. Notably, we have also discovered that cytokine responses to viruses are often very different between females and males and are seeking to understand why.

          This lab seeks researchers who are collaborative, highly motivated, innovative, hard-working and want to have a significant impact in the field of viral immunology. An outstanding academic record, excellent writing and oral presentation skills and a collaborative approach are essential. Trainees will have an opportunity to gain valuable, hands-on research experience in a variety of areas. Learning the fundamental principles of immunology, cancer biology and virology is an emphasis. Applicants who are willing to work longer hours than average, are passionate about pursuing a career in research, are excellent communicators, punctual, autonomous and possess excellent technical skills will excel in this laboratory. In return, members can expect diligent mentorship, access to state-of-the-art research resources, with opportunities spanning the basic to translational research spectrum, giving them the resources needed to potentially publish in the highest impact scientific journals and placing the future of their research career in their own hands.
