Peter_Oconnor.jpgImproving the performance and applications of Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometers. We work collaboratively with other research groups to demonstrate the effectiveness of higher specification FTICR mass spectrometry in specific applications. A particular focus in recent years has been on fundamental studies of the mechanism of electron capture dissociation, FTICR instrument design, post-translational modification analysis of proteins and peptides, deamidation and isomerization of aspartic acid residues in peptides and proteins, etc.

I am working on the following projects at the moment:

  • Project number 1
  • Project number 2
  • Project number 3

I am currently interested in improving the performance and applications of Fourier Transform Ion Cyclotron Resonance (FTICR) mass spectrometers; fundamental studies of the mechanism of electron capture dissociation; FTICR instrument design; post-translational modification analysis of proteins and peptides; and deamidation and isomerization of aspartic acid residues in peptides and proteins.

I am supervising the following PhD students:

  • Person 1, Topic 1
  • Person 2, Topic 2
  • Person 3, Topic 3

At the moment I am unable to accept any further applications, but if you get in touch I'll see if a member of my team might be able to help.
