I am a geologist and planetary scientist interested in mineral exploration (on any planet) and the relationship between geology, mineralogy and life.

These pages contain information about my research interests, publications, and teaching at the University of Hong Kong where I am an associate professor in the department of Earth Sciences, Assistant Dean for Knowledge Exchange, and Deputy Director of the Laboratory for Space Research.

Before joining HKU, I was a member of the Natural History Museum in London, United Kingdom, the Jet Propulsion Laboratory, and the Institut d'Astrophysique Spatiale in Paris. I carried out my graduate studies at Arizona State University between 2000 and 2005.
