Dr Nicholas Ariotti

Associate Director

Facility: Electron Microscope Unit
Category: Academic Staff

Education

PhD - Cell and Membrane Biology - The University of Queensland (2013)

BSc (Hons) - The University of Queensland (2006)

Role and Interests

My role is to provide training and support for clients in all facets of biological electron microscopy including sample preparation techniques, correlative light and electron microscopy and cryo-electron microscopy.

My research focuses on understanding how proteins are organised within the lipid bilayer of the plasma membrane and how changes in this organisation can result in disease.
