Post PhD

In January 2015, Joana began working as Chief Operating Officer at 'Healx' - a Cambridge start-up venture, doing data analytics and bioinformatics to find new drugs for rare diseases.

In March 2015 Joana then had a 3-month internship at the World Health Organisation in Geneva.

In September 2015 Joana started a consultancy position as an Associate with London-based company L.E.K.

Plain English

Intellectual disability (ID), or mental retardation, can have environmental or genetic causes. The genetic forms of ID are caused by mutations in genes that are important for the functioning of either mature brain cells (neurons or glia), or for the development of the brain itself. I am looking at how mutations in the NSUN2 gene, that codes for an RNA-processing enzyme, affects the formation of the different brain cell types from neural stem cells and cause intellectual disability in humans. More broadly, I would like to figure out why this and other enzymes that process RNA specifically cause intellectual disability disorders that are associated with ataxia and cerebellar dysfunction.
