Ian.Webb's picture

I am an analytical chemist with 10 years of mass spectrometry experience researching ion dynamics and reactions in the gas phase and mass spectrometry (MS) instrumentation research and development.  In the last year I have focused primarily on ion mobility spectrometry (IMS)/MS instrument development for enabling dissociation reactions of peptide ions in tandem with IMS/MS analysis and for lossless IMS/MS manipulations and drift time measurements for biological analyses. I have demonstrated essentially lossless ion transmission and IMS resolving power while turning an ion beam 90° and switching paths of ion packets as a function of their drift times. My background and expertise lies in: (i) extended experience with instrumentation and method development with ion optics utilizing inhomogeneous RF fields, (ii) doctoral and postdoctoral experience with implementing ion/ion and ion/molecule reactions in ion optical elements and (iii) experience with mass spectral interpretation for ion reaction products from biologically relevant macromolecules including peptides, proteins, drugs, oligonucleotides, etc. Currently I am working on new instrumentation for targeted pan-omics analyses.
