Kirsten Benkendorff

Kirsten Benkendorff is a marine biologist and biomedical researcher who teaches at Southern Cross University. Her research focuses on the nutritional and medicinal properties of seafood species and how they are affected by climate change, pollution and other environmental stressors. Her work has contributed 13 of the UN's Sustainable Development Goals, earning her over 8 million dollars (USD) in research funding.

Berkendorff is also a councilor, within the Malacological Society of Australasia as well as an associate editor at Scientific Reports and Marine Drugs.

Educational background Benkendorff obtained a Bachelor of Science from Macquarie University in 1994, followed by a PhD at the University of Wollongong in 1999. She was a career consultant for the Shellharbour Council in New South Wales, before becoming a lecturer in Marine Biology at Flinders University in South Australia, from 2006 to 2010, and then working at Southern Cross University.

Career Benkendorff research includes investigating bio-resource potential from marine mollusk, the effects of climate change and marine pollution, and medical applications of marine resources.

In study conducted over 2020 and 2021, Berkendorff, along with Endang Jamal, Amanda Reichelt-Brushett, Megan Gillmore, and Brandon Pearson, monitored pesticide runoff into the Richmond River estuary in Australia. They tested the effectiveness of oysters and passive sampling devices against composite water samples from the estuary. In total they were able to analyze 21 pesticides across the three methods. In 2020 they found more pesticides detected through the oysters than in the water samples, whereas in 2021 the passive sampling device detected more pesticides than the water sample. It was shown that it inhibited the activity of significant bacteria including Streptococcus spp. a bacteria responsible for pharyngitis, urinary tract infections, and life threatening cardiovascular alterations. The HPE of the Saccostrea g. was identified to carry many known antimicrobial proteins and peptides (AMPPs) known for helping to fight off such bacteria, and it was found to be non toxic in human lung cells above effective concentrations.
