I graduated with a degree in Biology and obtained my PhD at the University of Konstanz, Germany, having worked in the laboratory of Rolf Knippers on the assembly of nucleosomes during DNA replication. In 1994, I moved to Cambridge as a postdoc with an EMBO fellowship, working with Ron Laskey at the Wellcome/CRC Institute (now the Wellcome Trust/Cancer Research UK Gurdon Institute) on the regulation of human chromosomal DNA replication. I began to establish my own research group there from 1997 onwards as a Royal Society University Research Fellow. In 2000, I was appointed as a University Lecturer in Cell Biology and moved with my research group to the Department of Zoology.

Research Interests

I am interested in the control of chromosomal DNA replication in eukaryotic cells. Current research in my group focuses on the initiation step of DNA replication, and in particular, how it is regulated by the function of small non-coding RNAs.

Before a cell can divide, it needs to replicate its chromosomal DNA. A key regulation step for the cell division cycle is the initiation of chromosomal DNA replication at the G1-to-S phase transition. We have established a cell-free system from human cells that reconstitutes this process in a test tube. We have used this experimental system to purify and to characterise essential initiation factors. We are currently focussing on the roles of small non-coding Y RNAs, which we have identified as essential initiation factors in vertebrate cells.

Our main research interest is the elucidation of molecular mechanisms by which the small non-coding Y RNAs exert their function during the initiation of DNA replication in vertebrate cells. We are also exploring the roles of functionally equivalent RNAs in other, non-vertebrate organisms.

Finally, we have recently begun to investigate the specification and activation of DNA replication origins on the human genome.
