Chris is the inaugural Pro Vice-Chanellor (Graduate and Global Research), overseeing the La Trobe Graduate Research School and international research portfolio, and Professor of Physics. He has previously held the position of Dean of Graduate Studies, and Associate Dean (Research) in the Faculty of Science, Technology and Engineering at La Trobe.
Chris' research focuses on engineering diamond surfaces for quantum electronics, including the development of devices for spin transport and quantum computation. He leads the Diamond Research Group that uses a combination of synchrotron spectroscopy, scanning tunneling microscopy, device fabrication and magnetotransport.

Atomlab facilities and Instrumentation:
The group uses a combination of experimental techniques, predominantly synchrotron-based photoemission (soft X-ray spectroscopy at the Australian Synchrotron and AR-PES at BESSY), UHV scanning probe microscopy, surface and device transport measurements. The Atomlab houses and manages the following key facilities:
Createc cryogenic (6 Kelvin) UHV Scanning Tunnelling Microscope/qPlus Atomic Force Microscope with in-situ instrumentation for molecular dosing and passivation of surfaces and LEED.
SPECS Aarhus UHV Scanning Tunnelling Microscope with in-situ molecular dosing and LEED.
Oxford Instruments Teslatron
JEOL 4500 UHV scanning probe microscope with XPS, Auger, SEM and instrumentation for molecular dosing.
Cryomech helium liquifier. Microwave hydrogen plasma system for passivation of diamond surfaces.
