Kosmobac, WP3, looking at diffusion of macromolecules in vivo (in E.coli cells) and cell responses to osmotic shock using confocal (fluorescence) microscopy especially pulsed - FRAP

I am a PhD student working the group of Zoya Ignatova. Cellular and extracellular changes like crowding and osmotic stress conditions play a major role in protein aggregation. A change in the cytoplasmic composition is the result of an interplay between high osmotic pressures outside the cell volume and the cellular response to it in terms of uptake of K+ and secondary organic osmolytes. My research focuses on elucidating the role of natural osmolytes (known also as chemical chaperones or compatible ...

The focus of our research is the protein biogenesis and how stress-related factors modulate it. Protein biogenesis in general comprises various processes, i.e., translation, protein folding, each of which responds differently to external stress stimuli. Using systems biology approaches we seek to understand the interplay between these processes in fine-tuning the protein pattern and proteins’ abundance under osmotic stress conditions.

I am postdoc in the group of Prof Ian Booth in Aberdeen working on the biochemical and biophysical characterisation of bacterial channels.
