Research program title

Multi-scale Model Development for Active Learning Design of Beta-Sheet Forming Antimicrobial Peptides

Reference number



Program description

Antimicrobial peptides (AMPs) are short peptides produced by the innate immune system that represent a promising line of candidates for combating growing global antimicrobial resistance. Recent work has demonstrated the ability of the synthetic AMP GL13K to form non-amyloid beta-sheet aggregates on bacterial cell membranes and disrupt the cell, but the mechanism of action remains poorly understood at the molecular level. I seek a postdoctoral candidate to direct the performance of simulation-guided active learning for rational design and molecular-level understanding of GL13K-related AMPs. We will employ a deep learning technique called a variational autoencoder to transform the space of short peptides from a discrete combinatorial space—in terms of amino acid sequences—to a continuous latent space in which optimization is possible. Points of interest in the space will be identified with an active learning procedure such as Gaussian Process Regression and their quality assessed with multi-scale simulations of peptide interactions with eukaryotic and prokaryotic membrane mimics to optimize for peptides that preferentially bind and disrupt prokaryotic membranes. The impact of this work will be the development of new AMPs and rational rules for AMP design to combat antibiotic-resistant microbes.

Academic qualifications required

PhD in Biophysics, Biochemistry, or related fields with significant experience in multi-scale membrane simulations; some experience with machine learning techniques is a big plus.
