Luke A.J. O'Neill

Professor Luke A.J. O'Neill is Chair of Biochemistry at Trinity College Dublin, Ireland. He leads research at the intersection of immunology and metabolism, focusing on molecular mechanisms of inflammation and innate immune signaling. His work has pioneered understanding of TLR signaling, pro-inflammatory cytokines, and immunometabolism in immune cells.

• B.A. (Mod.) in Natural Sciences (Biochemistry), Trinity College Dublin (1985)
• PhD in Pharmacology, University of London (1988)

Key research themes include:

• Metabolic Reprogramming in immune cells during infection
• TLR signaling and inflammatory pathways
• NLRP3 inflammasome in diseases like COPD and autoimmune conditions
