BioMEX is a macromolecular structure solution service currently run out of the Science & Technology Facility Council.



As one of Europe's largest multi-disciplinary research organisations, STFC has access to a network of highly skilled experts who can assist with any stage of the data processing and structure solution service.

BioMEX Solutions provides access to some of the world's leading experts in the field of X-ray Crystallography structure solution. Currently our experts include:


Born in Australia, Professor Eleanor Dodson graduated with a degree in mathematics and philosophy from the University of Melbourne. She has played a key role in the development of mathematical and computational techniques to define crystallography.

Eleanor began her career in the 1960s when she was recruited for her mathematical skills to work in the group of the Nobel Prize-winner Dorothy Hodgkin at Oxford, which in 1969 solved the structure of insulin. In 1974, Eleanor along with several others founded a computing cooperative, which in 1979 became CCP4.

Eleanor arrived at York University in 1976 and has been a magnet for other crystallographers who came to work with her at York. It is therefore not surprising that the research group has grown to become the York Structural Biology Laboratory, with around 70 members.

Eleanor has additionally made major contributions to the theory and practice of methods used to determine the atomic structures of macromolecules, such as molecular replacement, phasing and refinement. Her pioneering work to develop analytical tools that allow non-experts to access modern crystallographic techniques led to her election as Fellow of the Royal Society in 2003.

Dr. Michail Isupov studied molecular and chemical physics at the Moscow Institute of Physics and Technology. He received his PhD degree in 1994 from the Moscow Institute of Crystallography in the laboratory of Boris Vainstein under the supervision of Emil Harutyunyan and Fred Antson (thesis title ‘Crystallographic Studies of Tryptophanse’). 

Michail has additionally spent several months in the York Structural Biology Laboratory working with Guy and Eleanor Dodson and at the EMBL Hamburg outstation working with Keith Wilson and Zbyszek Dauter. Michail’s post-doctoral studies began in 1994 at the University of Exeter, UK working with Jenny Littlechild. He is currently a Senior Research fellow in the Exeter Biosciences department.

Michail has collaborated with Garib Murshudov, Alexei Vagin, Andrey Lebedev and Fred Antson over the years. He is currently working in the field of protein crystallography of macromolecules and is interested in enzymatic catalysis and in methods development for macromolecular structure solution. To date Michail has published over 70 articles in peer-reviewed journals and deposited over 70 structures to the Protein Data Bank. He has expertise in structure solution by MR, MIR, SIRAS and MAD with Se-Met, halogen and intrinsic metal ion scatterers. Michail also has expertise in combining experimental and partial model phases, resolving space group ambiguities and phase improvement by density modification, using NCS features to resolve phase problems.
