Dr James Poulter

Profile

I am a Career Development Fellow in Functional Genomics, with an interest in neurodevelopmental disorders. I use a range of start of the art techniques including Next Generation Sequencing, CRISPR-Cas9 gene editing, stem cell differentiation and structural analyses to study the effects of mutations on the function of the encoded protein. In particular, I am interested in the mTOR signalling pathway and its role in the development of the cerebral cortex. I have strong collaborations with the Sheffield Institute for Translational Neuroscience (SITranN) and the Astbury Centre for Structural and Molecular Biology (University of Leeds).

Professional activities

STEM Ambassador (2015 – present)

Editorial Board Member for ‘The Biologist’ (Royal Society of Biology)

Studentships

Competitive fully funded PhD scholarships are available within the Faculty Graduate School. Self-funded students are always welcomed to apply for postgraduate study. International students must meet the entry requirements for English. Bench fees are required. Please email J.A.Poulter@leeds.ac.uk for informal enquiries.

Research interests

The development of the human brain is a highly orchestrated event, requiring a precise series of molecular events to occur at the correct time and location. The mTOR signalling pathway is one of the pathways responsible for orchestrating early brain development, in particular, the cerebral cortex. A failure of this pathway leads to the PIK3CA-related overgrowth syndromes (PROS), which encompass a range of disorders such as Tuberous Sclerosis and Epilepsy (focal cortical dysplasia type 2), that are characterised by over-activation of the mTOR signalling pathway. Using a range of cellular techniques such as CRISPR/Cas9 and stem cell differentiation, I create and characterise models of these disorders in order to better understand neurodevelopment with an aim to identify therapeutics.

Furthermore, in collaboration with the Astbury Centre for Structural and Molecular Biology, we produce purified proteins of interest to model the effect of mutations on their biophysical stability and their ability to function, using techniques such as Surface Plasmon Resonance. As well as functional studies, we use whole exome sequencing to identify mutations in families with neurodevelopmental disorders which are then assessed for pathogenicity using biochemical and cellular assays.
