Current Research

Projects available in my laboratory include:-

• Analysis of ubiquitin modification in response to DNA damage and replication stress
• Analysis of SUMO modification in response to DNA damage and replication stress
• The regulation of chromosome replication and segregation

Research Interests

All cells must ensure that their chromosomes are copied and segregated accurately during cell division and that any damage to their genetic material is repaired. Failure to do so will result in the sort of genetic alterations that lie behind disorders such as cancer, neurodegeneration and even ageing. Determining how cells normally act to maintain genome integrity, and identifying defects in these genome maintenance mechanisms in individual disease states, is therefore vital to our understanding of how disease develops and for identifying new possibilities for intervention and treatment.

Cells possess a complex network of DNA damage response (DDR) pathways that can detect problems with genome integrity and initiate a series of responses, such as DNA repair, arrest of cell cycle progression until the problem is rectified or, if the problem is too great, programmed cell death. Much of the signalling involved in DDR pathways relies on post-translational modification of cellular proteins to trigger changes in their behaviour. Protein phosphorylation events play a key role within many DDR pathways and have been the subject of intense study. More recently it has become clear that other post-translational changes, such as ubiquitylation and sumoylation, are also vitally important in genome maintenance.

My research interests are in understanding how cells maintain genome integrity and, in particular, in understanding the role played by ubiquitin and SUMO modification in this process. Through a combination of biochemical analysis, using purified proteins and cell-free extracts of Xenopus laevis eggs, and in vivo cell biological analysis using established human cell lines, my group is identifying key targets of ubiquitin and SUMO modification in the DNA damage response.

Current Teaching

Currently I teach the following modules:

Additional Information

I am the Director of Student Support for Lancaster Medical School. In this capacity I provide, co-ordinate and monitor both pastoral and academic support for students from all five years of study within the medical degree (MBChB) programme.
