Dr Helena Reinardy is a marine biologist and ecotoxicologist with extensive experience in biology of fish and marine invertebrates applied to various industries such as aquaculture, fisheries, environmental risk and safety, industrial waste management, and regulatory toxicology.
For the last 10 years, she has researched the complex interaction between organisms and their every changing environment. The current changes that are occurring the marine environment include climatic shifts such as increasing temperatures, reduction in pH, altered oxygen content, and presence of contaminants and pollutants. Combined, these multiple-level stressors affect organisms in the ocean, and their responses can determine susceptibility to disease, adaptive evolution, and long-term species resilience to changing environmental conditions. Helena has experience with a range of environmentally-relevant contaminants and stressors with projects into effects of oil, metals, radionuclides, pharmaceuticals, mutagens and carcinogens, nanoparticles, mine tailings waste, ocean acidification, and thermal stress. Helena applies a range of effects measurement spanning genetic and epigenetic levels changes to molecular toxicology, physiology, behaviour, reproduction, and survival.
Her research has both pure and applied angles and she works closely with partners and stakeholders from industry, governmental regulators, and national and international research sectors to understand environmental situations of concern.
Helena’s current post involves teaching aquaculture to undergraduate and graduate students, and conducting and developing research collaborations. In addition, she is affiliated to the University Centre in Svalbard as an adjunct Associate Professor in the Arctic Technology Department and supports research and education initiatives in environmental toxicology and chemistry.
