I was awarded my PhD from the International Max Planck PhD Program in Dresden Germany in 2006 with the grade summa cum laude; this project focused on the ‘Influence of mitochondrial energy metabolism on cellular function: implications for neurometabolic and neurodegenerative diseases.’
After which I worked in the Neurology department at the University Hospital Dresden as a research associate on an EU funded project investigating Co-enzyme Q deficiency in patient tissue.
I joined the Neuroscience department at the University of Sheffield in 2006 to set up mitochondrial investigations in models of Parkinson’s Disease working as a postdoctoral research associate with Prof. Oliver Bandmann.
I started my own lab when I became a Parkinson’s UK Senior Research Fellow in September 2013 based within the Sheffield Institute for Translational Neuroscience (SITraN).
I am currently a Senior Lecturer in Translational Neuroscience.
- Research interests
The main focus of my lab is mitochondria in neurodegenerative diseases, primarily focused on Parkinson’s Disease. This encompasses mitochondrial function, DNA, morphology and recycling.
My research focuses on both trying to further the understanding of the causes of mitochondrial problems in neurodegenerative conditions and in vitro drug screening for molecules which rescue mitochondrial function in patient tissue.
The lab has also recently become interested in investigating these mitochondrial abnormalities in Alzheimer’s Disease patient derived cells. It is interesting to investigate the differing mitochondrial phenotypes between neurodegenerative diseases and the mechanisms by which they occur and potentially drive neuronal vulnerability.
