Ian Cousins Professor

About me

I grew up in the ancient capital of Anglo-Saxon England; the City of Winchester. 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 received the Swedish academic title of Docent in 2003, successfully applied for a position as Assistant Professor at Stockholm University in 2004, was promoted to the position of Associate Professor in 2008 and Full Professor in 2012. I have published >220 peer-reviewed journal articles and 10 book chapters, which have been well cited (designated as a Highly Cited Researcher in 2018, 2020, 2024 and 2025). I previously worked as Associate Editor of Chemosphere (2012-2018) and became Associate Editor of Environmental Science and Technology in 2020 and Associate Editor of Environmental Au in 2021. In 2023, I was listed among the 30 EU politicians and professionals who have had the greatest impact on European environmental policy in the past two years. This recognition comes from the ENDS Europe Impact List of 2023.

I am currently course responsible for MI7028: Pollutant Dynamics, which occurs in Autumn Period C, and also teach currently in MI7014: Large Scale Challenges to the Climate and the Environment, MI7019: Contaminant Analysis, MI7026: Air Quality - From Emissions to Impacts and MI2009: Miljövetenskaplig metodik. I have been responsible for and taught in multiple other courses over the years (see cv).

I supervise masters' student research projects focusing on organic pollutants.

My research comprises a combination of experimental and modelling approaches to investigate the sources, transport, fate and exposure of contaminants. In recent years, much of my research has focused on per- and polyfluoroalkyl substances (PFAS). I work closely with analytical chemists in our department to better understand the behaviour of PFAS and other substances.

In 2020, we kicked off the PERFORCE3  project, which is a Europe-wide multi-partner doctoral research training programme in the field of PFAS coordinated by Stockholm University and funded by H2020. In 2021, we kicked off the ZeroPM project, which is a multipartner research project funded by H2020 and targeting PFAS and vPvB/PMT substances.
