I am a stream ecologist with most interest in the ecology of benthic inverterbates, particulalrly aquatic insects. I have studied streams and rivers in many parts of Victoria, and southern NSW and have been a curator and senior curator at Museum Victoria since 1981.

These days I mostly conduct quantitative sampling of streams and rivers to understand population dynamics and secondary production of individual taxa e.g. caddisflies, or whole communities.

For many years I have also examined community composition of benthic fauna throughout Victoria, often in conjunction with colleagues at Vic EPA or Monash University. The aim of many of these studies was to characterise benthic diversity in different parts of the state and relate changes in diversity and composition to environmental gradients such as altitude, levels of salinity, composition of bed sediments, physical disturbance and various other predictors of change in the faunal composition.

I have been extensively involved in the development of statistical models that predict benthic composition at sites with given environmental characteristics. These models use benthic composition at reference sites  to predict what might be present at sites of interest that could be subject to pollution, building of dams, alteration of river discharge and several other man-made disturbances of riverine ecosystems.

Projects and events

Editorships

I am currently the editor of the Memoirs of Museum Victoria. I am also an associate editor of Marine and Freshwater Research (CSIRO) and on the editorial board of Freshwater Biology (Wiley Blackwell).

I was the secretary of the Australian Society for Limnology for 30 years and the Australian Representative for the International Society of Limnology for 20 years.

Teaching and students

I have two current PhD students, one at La Trobe University and one at the University of Melbourne. I supervise these students jointly with colleagues at the universities.
