About me

My PhD project started in 2013 as a collaboration between Juha Kere and Peter Swoboda groups on Karolinska Institute Doktorand (KID) funding.

In Spring 2014 (3 months), Winter 2015 (2 weeks) and Summer 2016 (2 months), I had the priviledge to perform my research work in Junho Lee group at Seoul National University under STINT Sweden-Korea collaboration grant.

Research description

RFX transcription factor (TF) family has a conserved DNA binding domain that recognises a sequence motif called the X-box. The group of Dr Juha Kere specialises in human population genetic studies of complex diseases including dyslexia. Dyslexia candidate genes have been associated with RFXs because they harbour X-box motifs. The group of Dr Peter Swoboda has a long standing experience in C. elegans’ RFX TF known as DAF-19 which is the major regulator of ciliogenesis (in particular, primary cilium as the sensing organelle).

My main project is the characterization of human RFX transcription factor (TF) family by regulatory and target gene analysis. My primary interest is in the role of the RFX TFs in neuronal cilia and in the human brain. I used both computational and molecular biology techniques, and human cell lines and the worm C. elegans as model systems.
