Dr Jackie Mosely
Academic Lead
Jackie Mosely is a mass spectrometrist with research interests in instrument and application development, focusing on ionisation techniques for new molecules, expanding the capabilities of tandem mass spectrometry and ion mobility separation mass spectrometry.
She has been Chair of the British Mass Spectrometry Society, and now sits on the RSC separation Science group and manages the focus groups for the International Mass Spectrometry Foundation.
Dr Tony Larson
Technical Manager (Biology)
Tony has a background in plant and algal biochemistry, with specific expertise in developing LC- and GC-MS workflows for screening small molecules. He has worked across charity, industry, and funded research programmes to profile economically important target compounds, including polyunsaturated lipids, medicinal terpenes, and opiate alkaloids. Tony has a particular interest in developing software pipelines for processing large-scale untargeted metabolomic datasets.
Dr Adam Dowle
Senior Experimental Officer
Adam brings over 20 years of experience in mass spectrometry service provision to his role leading proteomic support within the BTF and CoEMS. His expertise spans the entire experimental pipeline—from initial design and data acquisition to complex analysis and reporting. Adam is highly proficient in a diverse range of methodologies, including DIA, DDA, TMT labelling, PTMs, and metaproteomics, as well as specialized applications like BioID and low-input sampling.
Dr Callan Littlejohn
Senior Technical Specialist (Mass Spectrometry)
Callan is a senior technical specialist with a background is in high-resolution mass spectrometry, advanced tandem MS/MS workflows, and polymer analysis. Since joining the University of York in October 2025, he has helped look after a diverse range of instrumentation within the chemistry division of CoEMS. He has a special interest in both analytical instrumentation and the data analysis of complex polymer degradation, and is always open to tackling challenging MS analysis projects.
Dr Chris Taylor
Technical Specialist
Chris is a senior lab technician specialising in protein characterisation, intact protein measurements, and the analysis of cross-linked peptides via LC-MS. His expertise spans 15 years working in mass spectrometry core facilities in both academic and charity sectors. Chris provides training in sample preparation and MALDI mass spectrometry, in addition to assisting with interpretation of results.
Dr Martina Conti
Technical Specialist
Martina is a technical specialist focusing on LC-MS and GC-MS method development and optimisation for small molecules, metabolomics, and lipidomics. She processes data for targeted and untargeted workflows using a suite of vendor and open-access software, creating bespoke workflows to support client research. Martina enjoys the diversity of her projects, training new scientists on instrumentation, and learning new techniques. She holds a particular interest in geochemistry and archaeological samples.
