Our long-term goal is to catalyze the progress of biomedical, analytical and forensic research through the development of mass spectrometric instrumentation. We currently have several major projects under way:

  1. New ways of fragmenting gas-phase bio-ions, including peptides and oligosaccharides, in tandem mass spectrometers using kiloelectronvolt helium ions. We use the term charge transfer dissociation (CTD-MS) to describe the mechanism of activation.  (example publication) 
  2. New forensic applications of isotope ratio mass spectrometry, including hair, nails and blow flies. (example publication) 
  3. Understanding the mass spectrometric fragmentation behavior of novel psychoactive substances (NPSs).  (example publication) 
  4. Development of new algorithms for mass spectral comparisons. 
  5. Experimental and theoretical approaches to understand the evaporation of ignitable liquids at elevated temperatures (e.g. 200 °C).  (example publication)
