Project Specification
Project Summary
We have recently developed technologies to produce synthetic RNA condensates with prescribed number, size, shape, composition, material properties and the ability to selectively recruit protein clients. These condensates form co-transcriptionally in synthetic cells. With this project, we aim to engineer interactions between the synthetic RNA condensates and synthetic cell membranes to induce controlled membrane deformation, patterning and division-like behaviours. Condensate/membrane affinity can be programmed using electrostatics or specifically with either amphiphilic nucleic acid linkers or aptamers targeting membrane proteins. Specific objectives include: 1) Build synthetic cells that can express RNA condensates with controlled affinity for the membrane; 2) Exploit processes such as condensate growth, degradation and internal phase separation to deform and manipulate the membranes (e.g. stabilizing non-spherical morphologies; controlling lipid domain formation, size and distribution; inducing membrane rupture or membrane fission).
The project involves secondments at the Max Plank Institute of Biochemistry (Munich, Germany) in the group of Prof. Petra Schwille and at Imperial College London in the group of Dr Claudia Contini.

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.
