On retirement in 1997, he was appointed Professor Emeritus at the same University. He is the author or co-author (with colleagues or as supervisor of post-graduate research programs) of publications dealing with various aspects of the biology of marine and freshwater microalgae and with studies of the freshwater resources of the tropical north of Australia. Since his retirement, he has continued to write reviews and has taken an active interest in current developments in his area of biological research. He is the author of two books previously published by Nova Science Publishers: Microalgal Cell Cycles (2010), Microalgae and Man (2013).
