Professor Andrew Weller

Interim Academic Lead

Andrew Weller is the interim Academic lead for CoEMS. His research focus is on synthetic and mechanistic organometallic chemistry for catalysis, and has an ongoing interest in the use of mass spectrometric techniques for the analysis of air and moisture sensitive inorganic and organometallic complexes. He has been chair of the management advisory panel for the EPSRC Mass Spectrometry Service, and is CoI and sits on the steering group in both phases of the EPSRC UK Catalysis Hub.

Dr Ed Bergstrom



My background is in the development and use of analytical instrumentation. I provide training and technical support for the CoEMS HPLC and mass spectrometry instrumentation, analysis method development and data analysis. 

Dr Tony Larson



My background is in plant and algal biochemistry with specific expertise in developing LC- and GC-MS workflows for screening small molecules. I have worked in charity, industry, EU, and BBSRC funded research programmes to profile a range of economically important target compounds including polyunsaturated lipids, medicinal terpenes, and opiate alkaloids. I have a particular interest in developing software pipelines for processing large-scale untargeted metabolomic datasets.


Dr Peter O'Toole


Peter is Director of the Bioscience Technology Facility (BTF) at the University of York, covering the broad technologies required for a multi- disciplined Department of  Biology. The BTF covers Metabolomics and Proteomics Lab as well as his own Imaging and Cytometry, Genomics and Bioinformatics, Molecular Interactions and Protein Production. The BTF is now actively seeking to bring these technologies together in a correlative process.
  • He has current research in developing label-free microscopy and correlative light and electron micro-scopy
  • Honorary Secretary for the Royal Microscopical Society
  • Actively involved with BBSRC strategy and working groups

Dr Adam Dowle



I have over 10 years’ experience of mass spectrometry service provision.  My main area of expertise is bottom-up LC-MS/MS-based proteomics, including: PTM identification, label free quantification (intensity-based and spectral counting), isobaric labelling (TMT and iTRAQ) and absolute quantification (AQUA and QconCAT).

Dr Swen Langer


Metabolomics and lipidomics in model and agricultural plants. I mostly develop methods on HPLC-FLD, GC-TOF, and LC-MS (ion trap, orbitrap) platforms, aiming to improve traits through breeding and transfer pathways in synthetic biology approaches.

Dr Chris Taylor

Technical Specialist

I have been working in the field of Life Science Mass Spectrometry since 2010. I am currently involved
in a range of core facility service provision including MALDI protein ID, intact molecular weight analysis and relative quantification via LCMS. I have a special interest in protein cross-linking mass spectrometry.

Damian Shaw

Research Support Officer I provide the Department of Chemistry with post-award research grant support, which includes administrative support to CoEMS; collating instrumentation usage and managing the organisation of the Management Group and Advisory Group meetings.
