Research interests

We aim to uncover the molecular mechanisms responsible for the membrane fusion between cells. This fundamental process of eukaryotic cell biology is what allows gametes to merge during sexual reproduction, a key evolutionary event in the emergence of complex life on our planet. In addition, cell-cell fusion is required for the development of syncytial tissues such as muscle and the placenta. Using yeast as our model system, we use a range biochemical and biophysical approaches to identify and characterize the molecular players which drive cell-cell membrane fusion.
