Research summary

Dr. Liam O’Neil is a member of the Manitoba Centre for Proteomics and Systems Biology, and his research focuses on understanding the biological events that occur prior to the development of rheumatoid arthritis.

He previously trained at the National Institutes of Health (Bethesda, MD) where he elucidated a mechanism linking neutrophil extracellular trap (NET) formation and autoantibody responses in rheumatoid arthritis.

 His aim is to better understand the pre-clinical phase of rheumatoid arthritis, interface immunology and proteomics to elucidate mechanisms of rheumatoid arthritis pathogenesis and ultimately improve patient outcomes.


Dr. Liam O’Neil obtained a bachelor of science in 2008 and a medical degree in 2012, both at the University of Manitoba.

He completed an FRCPC in internal medicine in 2016 and an FRCPC in rheumatology in 2017.

In 2020, he obtained a master’s of health sciences degree through Duke School of Medicine’s Clinical Research Training Program.

He was hired as an assistant professor by the University of Manitoba as a clinician-scientist in 2020.
