Research Interests and Biographical Information

Research comprises a combination of modelling and experimental approaches to investigate the sources, transport, fate and exposure of chemical contaminants. A suite of modelling tools are used to: (i) estimate key physicochemical properties of chemicals, (ii) simulate the transport and fate of chemicals in outdoor and indoor environments, (iii) simulate the bioaccumulation of chemicals in food webs, (iv) estimate human exposure of chemicals and (iv) simulate the pharmacokinetics of chemicals in wildlife species and humans.

There has been much recent focus on per- and polyfluoroalkyl substances (PFASs) which due to their unique environmental chemistry offer exciting new research opportunities. We work closely with analytical chemists in our department to better understand the behaviour of PFASs and other substances.

Biographical Information. I earned a BSc (Hons) degree in Chemistry at the University of York (1989) and a Master’s degree in Environmental Management at the University of Surrey (1991) before working as an Environmental Chemist in the water industry for 4 years (1991-1995). I returned to academia and earned a PhD at Lancaster University (1998), then worked as a Postdoc in Contaminant Fate Modelling at Trent University in Canada (1998-2001), and as a Visiting Researcher in Contaminant Fate Modelling at Stockholm University (2002-2004). I declined an offer to be Canada Research Chair in Environmental Modelling at Trent University in 2002 and instead took a position as Assistant Professor at Stockholm University in 2004. I was promoted to Full Professor in 2012. I have published more than 140 peer-review articles and 10 book chapters. I was designated as a Highly Cited Researcher in 2018.
