Internationally recognised for outstanding contributions to the engineering of biotechnological processes to industrial production scale levels, and in particular for the solution of the recalcitrant biochemical engineering problems associated with the commercial production of human growth hormone by genetically-engineered mammalian cells.

He has also made outstanding contributions to the education and training of biotechnologists and biochemical engineers in Australia and in south-east Asian countries.

He has played a leading role in fostering a better recognition of biotechnology as a profession in Australia and in the international scene.
