Tomas Malinauskas

Post Doctoral Research Associate

I am a structural biologist in Prof. Christian Siebold's group at the University of Oxford, UK. I use biochemical (mammalian cell-based protein expression, chromatography, cellular assays), biophysical (X-ray crystallography, cryo-EM, SPR, BLI, MALS) and computational (homology modelling, small molecule docking, evolutionary conservation analysis) tools to elucidate the molecular mechanisms of cell-to-cell communication. I aim to understand the way these mechanisms create and maintain living organisms.

If you need a structural perspective on your project, please email me. I am happy to help with anything from advice on protein constructs and expression to analysis of the target protein structure-function (e.g. the effect of mutations) to structural figures and movies for your papers.
