Project Summary
The Dimova Lab has extensive experience in the biophysical characterization of bio- and model membranes and giant vesicles as synthetic cells. The main objective of this project is to comprehensively examine the stability and mechanical properties of membranes in contact with biomolecular condensates. We will examine membranes either featuring a “molecular” condensate layer or by adsorbing macromolecules with condensate-forming domains. We will investigate the protective role of condensates and potential resealing of synthetic cells exposed to porating factors such as electric pulses, peptides and osmotic shock. We aim to elucidate the influence of macromolecular crowding on pore lifetime, potential pore occlusion and plugging by condensates, and the dynamics of membrane recovery.
The obtained results will inform strategies for developing advanced membrane-based technologies in biotechnology and medicine.
The project will include secondments at the Institute of Science and Technology Austria (Šarić group), École Normale Supérieure de Lyon, CNRS, France (Marques lab), and the Berlin branch of Nature Communications.

Doctoral Candidate (DC) Allowances:
MSCA Doctoral Networks provide attractive salary terms and benefits, including a living allowance of around €3,400 (country correction coefficient applies), a mobility allowance of €600 and, a family allowance (€660 if applicable). Note that these are gross values and employer costs or other deductions depend on the recruiting host.
Mobility Conditions:
MSCA networks require that applicants must not have resided or carried out their main activity (work, studies, etc.) in the country of the recruiting organisation for more than 12 months in the 36 months immediately before their recruitment date.
The individual scientific projects are planned within one of the partner Host Institution and every doctoral candidate will spend a part of their doctoral studies in another partner laboratory (a maximum of 12 months of their 36 months PhDs).
Standard duties and responsibilities of the DC:
For the 36 months of employment contract the doctoral candidate (DC) will be required to work exclusively on the MSCA programme. In all cases, all duties and responsibilities will be clearly outlined in the DC personal Career Development Plan, as determined in the early stages of the project between the DC and their supervisory committee.
Starting Date:
All projects will commence preferably within the first half of 2025, depending on the host institution. Contact the corresponding PIs for more details.
