Krysia is interested in the structural and functional ecology of marine and estuarine benthic communities, sediment processes, pollution, toxicology and data analysis.

Projects have included the impacts of petrochemicals on benthic community structure, bioturbation and sediment erosion patterns; recovery processes and dynamics in soft sediment habitats; impacts of climate change on features of conservation interest; and evaluation of indicators of environmental status.

Krysia is an applied ecologist and has produced more than 80 technical and advisory reports to government agencies and industry, aiming to understand and manage issues in the marine environment.
