Special Interests

Research Interests

My research has focused on the signalling mechanisms of inflammatory and immune cells. Recently, my research is directed at the role of viral infections such as influenza to impact the pathogenisis of lung injury. Previous work has demonstrated the ability of a particular bacerial product, LPS, to drive the expression of specific anti-viral genes in neutrophils. The finding that neutrophils express anti-viral genes has instigated studies into the role of neutrophils in complications of respiratory viral infections. We use both cellular and animal models of viral infection and patients to assess the role of neutrophils in lung injury.

Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.


Comments are collected in our Press Ganey Patient Satisfaction Surveys. Patients are de-identified to protect confidentiality and patient privacy. Learn more about our patient satisfaction survey.
