Louie Aspinall – Cryo-electron Microscopy Facility Manager

Louie specialises in cryo-EM sample preparation for single particle analysis studies, including negative stain TEM and cryo-EM workflows. He has expertise in DNA recombination systems and time-resolved cryo-EM studies.

Yehuda Halfon – Cryo-electron Microscopy Scientist

Yehuda specialises in the collection of cryo-EM data for single particle analysis and tomography workflows. He has experience in the use of structure to determine the function of macromolecules. 

Tom O’Sullivan – Correlative Imaging Scientist

Tom specialises in preparation of tissues and cells for cryogenic electron tomography, florescence microscopy, and correlative light and electron microscopy workflows. 

Oksana Degtjarik – Cryo-electron Microscopy Scientist

Oksana specialises in single particle analysis for cryo-EM data as well as structure determination and interpretation. She has experience with membrane proteins and membrane protein complexes. 

Martin Fuller –Electron Microscopy Technician 

Martin is a specialist in preparation of tissues and cells for ambient temperature transmission electron microscopy studies, including staining methods, freeze substitution and critical point drying.
