Alex is a marine biologist and oceanographic engineer by training, with multi-disciplinary research interests at the interface between marine ecology and oceanography. He has qualifications and experience in commercial and technical diving in both academic and industrial settings. He received Honours degrees in both Science and Engineering (Marine Biology and Ocean Systems Engineering) and a Ph.D. (Oceanography and Marine Ecology) from The University of Western Australia. He was a Fulbright Scholar and Postdoc at Scripps Institution of Oceanography, UC San Diego, and a Research Fellow in the Atmosphere and Ocean Research Institute at The University of Tokyo. His novel integration of oceanography, isotope ecology and engineering has begun to shed new light on the biogeochemical function, diet shifts, and foraging specialisations of globally threatened marine ecosystems and species. read more
