Mycology is the study of fungi, and he is particularly concerned with their identification and application in forensic and environmental investigations, especially microscopic fungi (including moulds), mushrooms and lichens.

In forensic science, their use as trace evidence in linking people or objects with places, estimation of post-mortem interval from growths on human remains, ascertaining times of deposition, and investigating causes of poisonings.

In environmental investigations, mould growth in buildings, including water damage and dating events, and assessments of air pollution using lchens.
