Multiple stressors are implicated in bee declines, but whilst our understanding of climate change and pesticides as drivers is improving, we lack a good mechanistic understanding of how they interact. Climate prediction models largely agree that average temperatures will rise but also with increases in extreme weather events. Whilst the direct implications of these forecasts will impose stress on bee health, are bees in for a double blow? Alongside changing temperatures, increases in pesticide usage are likely. A pressing question, therefore, is whether the severity of pesticide impacts on bees will increase under climate change?

Our mechanistic understanding of how pesticide residues can leave colonies vulnerable to environmental challenges remains poorly understood. To address this knowledge gap, we must first link how effects on individual functions and behaviours that are vital for colony performance are temperature dependent. From this, we can develop a mechanistic framework to determine how this translates to effects on colony-level function, such as thermoregulation for brood development, under changing climatic conditions. The goal of this project is to contribute to our understanding of how pesticide exposure under simulated cold snaps and heatwaves can contribute to honeybee colony losses. This will help in forecasting when in the season and across which climatic regions are honey bee colonies most vulnerable to pesticide exposure.

This PhD studentship will incorporate lab exposure assays to different pesticide classes across a temperature gradient. It will bring together three primary work packages over a three-year period, involving experiments to 1) understand how thermally dependent processes that underpin energy metabolism and body thermoregulation are influenced by pesticides across a temperature range; 2) Quantify the pesticide thermal response relationships of behaviours that are dependent on metabolic rate and body thermoregulation; 3) Assess how collective behaviour and thermoregulation of brood under different cold and warm conditions are affected by pesticide exposure.

Dissecting factors driving the Staphylococcus aureus intracellular lifestyle

Applications are invited for a research studentship leading to the award of a PhD degree, under the supervision of Dr. Ana Eulalio, to investigate bacterial determinants of the intracellular lifestyle of the bacterial pathogen Staphylococcus aureus, and their impact on pathogenesis and antibiotic treatment.

The post is supported by a bursary and fees (at the UK student rate only) funded by the Department of Life Sciences. The studentship is for 36 months.

Staphylococcus aureus is a leading cause of human infections worldwide, causing a broad range of community- and hospital-acquired infections. Although S. aureus is historically considered an extracellular pathogen, substantial evidence demonstrates that S. aureus can be internalized by various cell types. Recently, our lab characterized the interaction of a large collection of S. aureus clinical isolates collected from patients with bone/joint infections, bacteremia, and infective endocarditis with host cells (epithelial and endothelial cells, osteoblasts and macrophages). This analysis revealed that the vast majority of the isolates are facultative intracellular and identified seven intracellular phenotypes, with various levels of replication, persistence, and host cell death. The presence of S. aureus inside host cells can contribute to its ability to evade antibiotic treatment and immune responses, explaining, at least in part, treatment failure and recurrence of disease.

Despite the relevance of the intracellular lifestyle to S. aureus pathogenicity, a comprehensive identification of host and bacterial factors relevant to this process is yet to be performed. We are addressing this question by applying functional genomics approaches, specifically: i) microscopy-based, high-throughput screenings of S. aureus mutant collections (for bacterial factors) and siRNA/CRISPR libraries (for host factors); ii) transcriptomics and proteomics to identify host and bacterial factors regulated during infection with S. aureus clinical isolates.

The PhD student will pursue a project along the above-described lines of research, particularly focused on characterization of key S. aureus factors controlling the intracellular lifestyle. The PhD student will receive training in microbiology and cell biology approaches, including bacterial and mammalian cell culture, microscopy, transcriptomics, and high-throughput screening.

Using multiomics and AlphaFold to develop new bioinformatics approaches to aid personalized medicine
Project Description

Applications are invited for a prestigious EPSRC research studentship leading to the award of a PhD degree, under the supervision of Dr. Alessia David (Dept of Life Science) and Prof Johnson (Dept of Medicine), to develop new bioinformatics approaches for the identification of new genes and genetic variants responsible for human disease. The post is supported by a bursary and fees (at the UK student rate only) are funded by the EPSRC. The studentship is for 36 months from October 2025.

The identification of genes and genetic variation responsible for human disease and the interpretation of their function within a biological network is a crucial step towards personalized medicine and the discovery of novel biomarkers. DNA sequencing projects from individual research groups and the 100K Genomes Project at Genomics England are providing an unprecedented amount of DNA sequencing data that need to be analysed to derive biologically meaningful information. This task cannot be performed manually and requires computational resources.

Recent major development in the field of 3D protein modeling with AlphaFold and the unprecedent wealth of information now available for genome variation in human and model organisms allow to expand the use of multiomics to develop new prediction algorithms to identify genes and genetic variants that can disrupt protein function/structure and biological pathways. In this project you will develop new robust bioinformatics algorithms for predicting the effect of genetic variants and identify new candidate genes for human disease. You will use the wealth of information on gene expression, protein interactions, and three-dimensional protein structure, experimentally determined and modelled by the in house Phyre2 homology modeling software and by the deep learning algorithm AlphaFold. You will apply these new bioinformatics algorithms to genomic and clinical data to interpret their biological relevance. You will have the opportunity to develop effective visualisation web tools to make these new algorithms available to the biomedical community. You will work closely with clinicians to design bespoke approaches that ensure the utilization of these new bioinformatic resources by the biomedical community. Programming experience, preferably in Python, is essential for this position.

The Department of Bioinformatics in the Department of Life Sciences at Imperial College has strong expertise in developing robust bioinformatics resources for the biomedical community, such as the Missense3D prediction algorithm suite for the interpretation of genetic variants (> 8000 users and > 400 citations since its release in 2019) and the Missense3D-DB database, a large catalog of precomputed predictions for 4 million human genetic variant which is included in DECIPHER at the European Bioinformatics Institute. The group of Prof M Johnson, in the Department of Medicine, has extensive expertise in using cell transcriptomics data in particular for the identification of new genetic mechanisms underlying neurological disorders.

You will receive training in the use of genomics, proteomics and 3D protein structures to develop new bioinformatics resources and in their application to analyze patients’ genetic data.
