Multiscale modelling of actin filaments


We are currently seeking a highly motivated postdoctoral fellow who will be mentored by Dr. Matthieu Chavent (IPBS, Toulouse, http://matthieuchavent.com ) and Prof Jean-Philip Piquemal (Sorbonne University, Paris, https://piquemalresearch.com ). The researcher will be hosted in Dr Chavent’s lab in Toulouse and will regularly visit Prof Piquemal in Paris. The postdoc is funded for 2 years with a possibility of extension. It will start beginning of 2021. The deadline to send an application is the 1st of December 2020.



The goal of this project is to investigate, at the atomistic level, the mechanics of actin filaments and understand how external forces can modulate them. To do that, the candidate will perform high performance computing of polarizable forcefield using Tinker-HP [1], atomistic simulations, and up to coarse-grain models [2]. The results will then be combined to numerical and analytical models developed by our collaborator Dr Dmitrieff to design new mesoscale models [3]. The models will be validated at different scales by our collaborator experimentalists (see bellow).
