Research Interests

Fungi impact on human life in many areas such as health and wellness, agriculture, horticul-ture, biotechnology, and food production. Knowledge in fungal biodiversity, fungal biology and fungal ecology constitutes the fundamentals towards understanding, exploiting and managing fungi in these different areas. The Mycology and Fungal-Plant Interactions Laboratory focuses on the twin approach of studying the biodiversity of local/tropical fungi, and the exploitation of se-lected fungi. Under biodiversity studies, the present key interests are in the aquatic and marine fungi of which about 200 local species have been recorded, and endophytic symbiotic fungi of agricultural/horticultural relevance. Applied mycological interests focus on fungal enzymes, fun-gal symbiosis in orchids, fungal chitosan, and fungal airspora in relation to allergenic responses.
