Topics:

1) Antimicrobial peptides and their key properties for membrane permeation

Antimicrobial peptides (AMPs) can disrupt the membrane barrier function and kill bacteria, including resistant bacteria recognized by the UN and WHO as one of the biggest threats to global health. AMPs are part of the host-defense system of many organisms and promising candidates to become a new class of therapeutics. The aim of this project is to design new peptides that disrupt the membranes of pathogens. To obtain such peptides, we will establish the relationship between peptide sequence motifs and their ability to disrupt bacterial membranes. This ERC funded project will be complemented by experiments providing verification and feedback of membrane disruption. The main tool will be Molecular dynamics simulations with free energy calculations using Gromacs program package.

2) Synergistic translocation of multiple peptides 

Translocation of peptides across cell membranes is one of the mechanisms by which antimicrobial peptides can kill bacteria. Moreover, such peptides can act as cell-penetrating peptides delivering drug cargos to the cell. Despite the potential of such peptides, their development is hindered by the lack of knowledge about the peptide sequence-to-function relationship. In this project, we will take advantage of peptide synergism, in which peptide mixture is more effective than its components. In particular, the project is focused on the co-translocation of multiple peptides. The main tool will be Molecular dynamics simulations with free energy calculations. Part of the project could take advantage of Monte Carlo simulations with a highly coarse-grained model.

Eligibility: Outstanding candidates with experience in computer simulations and with an MSc/PhD degree in the fields of biophysics, soft matter physics, physical chemistry, computational chemistry, statistical mechanics, or related fields. Experience with molecular dynamics simulations (with GROMACS, CHARMM, NAMD, AMBER, LAMMPS, etc.) or other simulation techniques (Monte Carlo, DPD, etc.) at the atomistic or coarse-grained level would be an advantage.

Computing Resources: Successful candidates will have access to local computing clusters with 2500 cores and 100 GPUs. Access to Metacentrum NGI – National Grid Infrastructure for computing (with ~20,000 cores) will be also available. Additional resources include the possibility of applying for IT4Inovations, where the group is active.

Competitive salary: depending on the position - supported by grant projects including ERC consolidator grant.

Application procedure: Applications must include a CV, with list of publications and study results, short personal statement (description of research interests, past, and plans), and the name of a person willing to provide a letter of recommendation. Applications with all this material (preferably in a single pdf) should be sent to Robert Vacha (robert.vacha@mail.muni.cz).
