About us

King’s College London is a world-leading Russell Group university with an outstanding international reputation for research and education. This post will be based in the Drug Discovery Department within the Institute of Pharmaceutical Science and will form part of a multidisciplinary collaboration between Professor Miraz Rahman and Professor Julian Naglik in the Centre for Host-Microbiome Interactions. The project brings together complementary expertise in medicinal chemistry, drug discovery, fungal pathogenesis and host–pathogen interactions, providing an excellent environment for collaborative and translational research.

About

The Role

Candida albicans is a major fungal pathogen that can cause severe morbidity and life-threatening infection. A key virulence factor is candidalysin, a peptide toxin secreted by C. albicans hyphae that drives epithelial damage, cell activation and mucosal inflammation.

The postdoctoral researcher will play a central role in the discovery and optimisation of peptide and peptidomimetic inhibitors that neutralise candidalysin activity. The role will focus on the design, synthesis, purification and characterisation of inhibitor series, working within an iterative medicinal chemistry programme informed by computational modelling, biophysical measurements and biological activity.

The researcher will develop and optimise synthetic routes, undertake parallel synthesis where appropriate, and scale up selected compounds for detailed biophysical and biological evaluation. They will use analytical and preparative HPLC, LC-MS, NMR and other appropriate techniques to confirm compound identity, purity and quality. A major part of the role will be to interpret emerging structure–activity relationships and use experimental data to guide subsequent inhibitor design.

The researcher will work closely with the computational chemist and with Professor Julian Naglik’s team, who will evaluate inhibitor activity in relevant biological models. This close integration of chemistry, modelling, biophysics and infection biology will support rapid prioritisation and optimisation of compounds with the greatest therapeutic potential.

The post is particularly suited to a synthetic organic or medicinal chemist with strong practical experience in compound synthesis and characterisation. Previous experience in peptide or peptidomimetic chemistry would be advantageous but is not essential.

The researcher will be funded by the BBSRC and based in the laboratory of Professor Miraz Rahman at King’s College London, where they will undertake independent, original research within a multidisciplinary drug-discovery programme.

This is a full time post (35 Hours per week), and you will be offered an a fixed term contract until 31st December 2028.
