Temperature variations have a big impact on bacterial metabolism and death, yet an exhaustive molecular picture of these processes is still missing.
For instance, whether thermal death is determined by the deterioration of the whole or a specific part of the proteome is hotly debated. Here, by monitoring the proteome dynamics of E. coli, we clearly show that only a minor fraction of the proteome unfolds at the cell death.
My research
Having a background in theoretical and experimental physics, for several years now I have been focusing on the field of biophysics. In this field, I apply neutron scattering to biological samples. We study molecular dynamics and structure at the atomic level and try to relate them to the functionality of biological systems.
