Anne Donaldson investigates how cells replicate their DNA, a central biological process that is essential for cell multiplication. Her research group is funded by major grants from Cancer Research UK and the Wellcome Trust. Within the Institute of Medical Sciences Anne leads the 'Chromosome & Cellular Dynamics' Section, consisting of six research groups who share interests in chromosome dynamics. Anne teaches on topics related to chromosome maintenance on several undergraduate and graduate-level courses.
After her Bachelors degree in Natural Sciences at the University of Cambridge, Anne completed her PhD at the MRC Laboratory of Molecular Biology, then moved as a NATO/SERC postdoctoral fellow to the University of Washington in Seattle. Anne established her lab as a Royal Society University Research Fellow at the University of Dundee, and in 2001 Anne was chosen as an EMBO Young Investigator. The Donaldson laboratory has been at the University of Aberdeen Institute of Medical Sciences since 2003.
Anne served as Organizer of the Cold Spring Harbor Eukaryotic DNA Replication & Genome Maintenance meeting from 2014-2019.
!!We have Postdoc and PhD positions available in the lab, funded by the Wellcome Trust and by Cancer Research UK!!

Human cells contain 1.8 metres of DNA in a nucleus only about 6 microns in diameter. During chromosome replication this entire length of DNA must be duplicated exactly once with perfect accuracy, so that the strands can be disentangled and precisely segregated to the daughter cells. The DNA is extremely vulnerable to damage during this process, and cells must deal with thousands of potentially lethal DNA damage events every single day. Members of the Donaldson lab investigate the molecular controls over DNA replication and damage repair. Understanding chromosome maintenance will suggest new therapeutic strategies in the fight against cancer, as well as illuminating the basic mechanisms at the heart of the cell division cycle.
The budding yeast S. cerevisiae provides an excellent model organism for studying the fundamentals of chromosome biology, because of the remarkable molecular genetics tools available for this system. DNA replication initiates at multiple sites on each chromosome called replication origins. We use molecular genetics to understand the processes of yeast DNA replication, which we then investigate in human cells. Using this approach we have discovered several molecular mechanisms of replication control that operate throughout eukaryotic cells.
Our focus of interest is understanding the molecular machinery controlling origin initiation, replication fork progression, and chromosome maintenance. We use a combination of advanced proteomic, biochemical, genomic and microscopy methods to investigate the cellular components that regulate these DNA replication and repair processes.
