Brief synopsis of current research:
Quaternary palaeoecology, and the use of freshwater midges (Diptera: Chironomidae) as environmental indicators - especially their use as biomonitors of past climatic change, lakewater salinity, eutrophication, and pollutants. Relationship between distributions of aquatic organisms and their environment. Ontogeny of lake ecosystems in relation to internal processes, human impacts and climatic change.
