Characterising lipid-protein interactions through computational modelling


Background

I obtained my undergraduate degree in Biochemistry from the University of Oxford in 2014. My final year masters project involved investigating lipid interactions of the human receptor tyrosine kinase (hRTK) family of membrane proteins, and was supervised by Dr Heidi Koldsø.

My DPhil is co-supervised by Prof Mark Sansom and Dr Heidi Koldsø. I am funded by a scholarship from the MRC and the Department of Biochemistry.


Research

My research involves application of molecular dynamics to probe the lipid interactions of biomedically important membrane proteins. The current focus of my research is on the interactions of the epidermal growth factor receptor (EGFR) and the Insulin receptor (IR) with the modulatory glycolipid GM3 and the phosphoinositide PIP2 at the plasma membrane. Additionally, I am working on projects examining cardiolipin interactions with the ADP/ATP carrier (AAC1/ANT) within the inner membrane of mitochondria.
