"in no area of biology have ideas arisen so often in advance of times as in genetics or its offshoot, molecular biology."

Research with a small group of students and associates resulted in the development of the ascomycete fungus Aspergillus nidulans as a convenient genetical tool.

Now a 'model' organism, mutated 'Glasgow' strains of A. nidulans are employed in genetical research world-wide and the genome of the starting strain has been sequenced.

One important outcome of this work was the establishment with Alan Roper of the Parasexual Cycle, asexual reproduction, in fungi.
