Professor Helen Cooper Expert mass spectrometrist

Helen J. Cooper is Professor of Mass Spectrometry in the School of Biosciences at the University of Birmingham. Her research interests focus on gas-phase ion chemistry of biomolecules and other biologically-relevant species. A particular interest is radical-driven fragmentation. More recently, her interests have focused on ambient surface mass spectrometry and ion mobility spectrometry.

Helen obtained her BSc and PhD in Chemistry from the University of Warwick. After a brief spell in industry, she returned to the University of Warwick before moving to Florida State University in 2000. She returned to the UK, taking up a post at the University of Birmingham, in 2003.
