Sally completed her PhD in the Mitochondrial Research Group in Newcastle, UK in 2012 under the supervision of Professors Doug Turnbull and Hanns Lochmüller. Her thesis examined the presence of mitochondrial DNA deletions in muscle stem cells (satellite cells) in patients with mitochondrial myopathies.

Following her PhD, she moved across the Atlantic to Montreal to begin what would be a 4-year post-doctoral position with Professors Tanja Taivassalo and Russell Hepple, at first at McGill University and then at the McGill University Health Centre. Initially she worked on projects examining the role of mitochondria in clinical conditions (e.g COPD) and ageing, and later moved on to explore the role of neuromuscular junction (NMJ) stability in ageing. In 2016 she returned to the UK and Newcastle to work with Professor Lochmüller on a project to test novel treatments for patients with congenital myasthenic syndromes (disorders of the NMJ).

Sally is extremely excited to have returned to Canada and to be helping Professor Lochmüller set up his lab in Ottawa.
