Keywords: Oncology, cancer therapeutics, immunotherapy, oncolytic virotherapy, translational oncology and clinical studies

Profile(s): University of Guelph Experts, Department of Pathobiology

Current Positions:

  • Associate Professor of Viral Immunology – Department of Pathobiology, University of Guelph, Ontario Veterinary College
  • Faculty Affiliate – One Health Institute, University of Guelph

Seeking Partnerships in the Areas of:

Biotherapies for cancer treatment, Cancer immunotherapy, Cancer treatment without toxicities, Minimizing therapy toxicity, Oncolytic virotherapy, Viruses that Replicate in and kill cancerous cells

Education and Employment Background:

  • BSc – Biomedical Science (University of Guelph, Guelph, ON) 
  • MSc – Immunology (University of Guelph, Guelph, ON) 
  • PhD – Immunology (University of Guelph, Guelph, ON) 
  • Postdoctoral fellowship – Oncolytic Immunotherapy (McMaster University, Hamilton, ON)

Research Themes & Interests:

Research in the Bridle lab 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.
