Keynote Speakers

Dr Stephen Lofts

Stephen Lofts is a soil and aquatic chemist at NERC-CEH with 21 years experience. His specialism is in the chemistry, fate and bioavailability of contaminants in the soil and freshwater environments, with an emphasis on developing and applying models of their speciation, fate and ecological risks. He has played a leading role in the development of the WHAM speciation model and its application to issues of metal fate and bioavailability. He also has interests in the environmental behaviour of manufactured nanoparticles and is currently engaged in EU-funded projects to measure and model their fate and biouptake in soils and waters, and to improve their analytical characterization in real environments.

 

Dr Charlotte Nys

Charotte Nys is an early career post-doctoral researcher based at the Laboratory of Environmental Toxicology and Aquatic Ecology, GhEnToxLab, at Ghent University, Belgium. Her research focusses on the effects of water chemistry on chronic metal toxicity and metal mixture toxicity to aquatic organisms. Charlotte is mainly interested in integrating the knowledge about bioavailability effects and mixture toxicity into scientific models and tools which increase the ecological relevance of environmental risk assessment procedures and water quality standards derivations for metals. These tools are currently being integrated into European Environmental Regulatory Frameworks such as REACH and the Water Framework Directive.

 

 

Prof John Sumpter

John Sumpter teaches and conducts research at Brunel University London, UK. He has spent essentially all of his academic career at this university, having first joined it as a lecturer in 1978. He is probably best known for is research on ‘gender-bending’ chemicals in the aquatic environment and their effects on fish. His current research is focused on the potential effects of human pharmaceuticals on fish, with synthetic steroid hormones and psychoactive drugs receiving most attention. He has also become concerned about the apparently poor quality of a significant proportion of published ecotoxicology research, and in consequence has published a series of papers covering various ways of improving the current situation. His research is highly cited: his 250 papers have been cited over 30,000 times to date, giving him an h-index of 80. He has received a number of scientific awards, including the 2007 Founders Award from SETAC.

 

A/Prof Susan Bengtson Nash

Susan Bengtson Nash found her passion for environmental toxicology as an honours student investigating the relationship between persistent organic pollutant burdens and ovarian histology in Danish harbour porpoise. After completing her PhD on bioassay development at the University of Queensland, Australia, she established the Southern Ocean Persistent Organic Pollutant Program (SOPOPP) with Australian Research Council funding. SOPOPP research seeks to fill significant research gaps surrounding contaminant transport to the south polar region; contaminant behaviour and fate in a changing polar landscape, as well as effects upon polar biota and ecosystems. Associate Professor Bengtson holds a research academic appointment at Griffith University, serves on the International Whaling Commission steering committee for contaminants and currently contributes active research projects under, amongst others; the Southern Ocean Observing System; Australian Antarctic Science Program and the Australian Research Council.

 

Prof Scott Smith

Dr. Scott Smith is a full Professor in the Department of Chemistry and Biochemistry at Wilfrid Laurier University in Waterloo, Ontario, Canada.  His areas of expertise include nutrient removal and recovery, aquatic geochemistry with a focus on metal-organic matter interactions, and metal toxicology. Scott is an applied chemist who often collaborates with other scientists and engineers in industry and academia.  For his paradigm shifting work on mechanism and modelling of chemically mediated phosphorus removal Scott was nominated for the 2015 Canadian national NSERC John C. Polyani award.  Scott’s lab has made contributions towards the development of bioavailability approaches, such as the Biotic Ligand Model (BLM), to understand and predict metal toxicity in freshwater, wastewater and saltwater environments.  Scott’s main role in this collaborative work with toxicologist and physiologists has been his experimental determination of free metal ions by electrochemical and spectroscopic methods as well as the optical and chemical characterization of organic matter of diverse origin.
