I’m interested in  understanding how the mammalian brain develops. I have previously studied how heparan sulphate regulates Fgf signalling during brain development. In collaboration with Dr Richard Mort of Lancaster University, we have developed a live imaging platform to examine the cell cycle during brain development.

Currently, I am using cerebral organoids to model brain development. In particular, I am investigating the role(s) of possible signalling centres in developing cerebral organoids.

Human & mouse embryonic stem (ES) cell culture

Primary cell culture

Cell cycle analysis (BrdU, EdU)
