The Department of Life Sciences at Imperial College London has funding for 3 PhD studentships, to commence 3rd October 2020. 

We wish to widen participation and therefore we strongly encourage applications from individuals who completed their bachelor's and/or master's degrees at non-Russell group Universities. We are particularly keen to get applications from underrepresented groups (e.g. BAME candidates).  

For candidates with a non-Russell group background, we are offering an online workshop (29 April)  and Q&A (6 May) sessions where we will provide both information on life as a PhD student at Imperial, and advice and support for application and interview process for a PhD position. Candidates can register their interest in attending these events here 

For information on the specific advertised projects please contact the relevant supervisor (see below). For additional information on the general support provided to PhD students at Imperial College and within the Department of Life Sciences contact Rozan Hamilton-Nixon ( 

Funding and Eligibility: The studentships will cover UK tuition fees of £4,500pa and will provide an annual tax -free maintenance stipend of £17,609, in 12 monthly instalments. Studentships are expected to last for 36 months, subject to satisfactory progress. A BSc in biological, or related, sciences is required at Upper Second Class level or better and candidates with a Master's degree, in addition to the BSc, might be given preference. Candidates must be either UK or EU nationals with settled status, resident in the UK for at least 3 years prior to the commencement of the studentships. Non UK/EU nationals are not eligible. 

Information on the application process can be found here

Deadline for applications: 12noon, 21 May 2021

Catching a killing machine in the act: visualizing the membrane attack complex (MAC) in bacterial minicells.

Catching a killing machine in the act: visualizing the membrane attack complex (MAC) in bacterial minicells. 
Dr. Doryen Bubeck; 

Complement is one of the immune system’s first responders to infection. Pathogen detection by any of the three complement cascades triggers formation of the membrane attack complex (MAC), a lytic pore that directly destroys Gram-negative bacteria.  MAC assembles in a sequential and irreversible pathway to form an 11 nm hole in the lipid bilayer. As the pore dimensions are only compatible with traversing the outer membrane of Gram-negative bacteria, it remains unclear how MAC damages the inner membrane to cause cell death. This project will explore structural biology approaches to investigate how MAC kills bacteria. In doing, so we will provide insight into the mechanism of action of an immune pore which has the potential to inform why some bacteria are resistant to MAC.

Understanding the eco-evolutionary dynamics of overlapping plant species’ ranges.

Understanding the eco-evolutionary dynamics of overlapping plant species’ ranges. (Dr. Will Pearse;  

Understanding how species’ ranges change and evolve is a long-standing problem in ecology and evolution. It is widely thought that lineages of species whose traits evolve more rapidly compete less with one-another and so are more likely to have overlapping ranges, but directly testing such hypotheses is challenging. This project will leverage two statistical frameworks recently developed in the lab (Pearse et al. 2019) to understand how lineages’ traits and ranges co-evolve. Making use of global plant distribution, trait, and phylogenetic data, this project will explore how the ecological rules that determine species’ ranges have evolved. These joint eco-evolutionary models will permit more accurate forecasts of species’ ranges by using evolutionary information to highlight commonalities across species. These insights will be used to inform ongoing conservation planning, which has highlighted uncertainty in the mode of evolution of species’ traits as a major source of error when spatially prioritising global conservation (Mazel et al. 2018).

Structural and functional investigation of the human Vitamin C transporter.

Structural and functional investigation of the human Vitamin C transporter. (Professor Bernadette Byrne; 

The human Vitamin C transporters, hSVCT1 and hSVCT2, belong to the Nucleobase Ascorbate transporter (NAT) family of proteins.  hSVCT2 is key in the anticancer effects of ascorbic acid. hSVCT1 has been expressed in both Xenopus oocytes and COS cells and the protein used to study function and obtain a low resolution structure.  However very little is known about these proteins, in particular how these differ in terms of substrate specificity and regulation compared with the NAT family proteins from bacteria and other eukaryotes. This project will initiate studies on the hSVCTs, designing and generating expression constructs and expressing the proteins in mammalian cells in order to allow us to obtain the most physiologically relevant material for study. The protein will be isolated using established detergent based extraction and purification protocols and the sample submitted to basic biophysical analyses to check for purity and stability. Earlier work in our laboratory has successfully stabilised a fungal NAT, UapA, for crystallographic purposes by the introduction of a single point mutation in the NAT signature motif sequence. We will attempt mutagenesis of the SVCTs based on this and other possible stabilisation sites. The most stable protein will be submitted to structural analysis using cryo-EM and if time and protein allows we will work with our collaborators at Kings College to attempt to understand the role of lipids in the structure and function of hSVCTs.
