I am a Postdoctoral Research Fellow in the lab of Prof. Michael Schrader, investigating the molecular mechanisms underlying peroxisome dynamics. My previous research has focused on how post-translational modifications regulate organelle function and protein trafficking in healthy and diseased states. In particular, my work on the dysfunction of mitochondrial dynamics in Parkinson’s Disease led me to an interest in peroxisomes, because of the shared machinery between the two organelles. In the Schrader lab, I use a variety of molecular, biochemical, imaging and biophysical techniques to investigate how peroxisome number and function is controlled.
