Postgraduate supervision

Expressions of interest are welcome from prospective honours, masters, and PhD students. Both domestic and international candidates are encouraged to submit their expressions of interest. Successful candidates will be offered the opportunity to conduct world-class research in the COSMOS group.

Galvanised by the studying, training, and living experiences in various parts of the world (North America, Europe, Africa, Australasia), I founded the COSMOS group in 2012. The group focuses on translational, clinical, and epidemiological research at the interfaces between pancreatic diseases, metabolic derangements, nutrition and gut function. COSMOS strives to be diverse, inclusive, and culturally sensitive. It espouses the principles of equity to create meaningful learning experiences for all members of the group. COSMOS fosters powerful and potentially world-changing collaborations built on innovative ideas that occur at the intersections of disciplines, fields, and cultures.
