Bio & Research Interests

I am currently employed at Seqwater as a Senior Scientist and have an Adjunct Research Fellow in the
Australian Rivers Institute at Griffith University. I have a PhD from Griffith University in Ecology having
investigated the trophic dynamics of a sub-tropical reservoir.

My research focus has been on freshwater ecosystems including the fish ecology, limnology and water
quality processes. Recent research includes the assessment of catadromous fish migratory needs,
assessments of fishway performance, Australian Lungfish ecology and behavioural patterns. I am currently
part of the research team on the ARC grant “Have we already lost the Australian Lungfish?” investigating
the population dynamics and vulnerability of this unique Australian fish.
