Research interests

It is well established that exposure to ambient particulate matter can lead to negative health effects. However, the underlying mechanisms are still not completely understood and there is a lot of uncertainty regarding which particles are the most toxic and why (differential toxicity). My research focusses on trying to understand which particles are the most detrimental to human health and how this relates to their chemical composition. To study this, we are not only comparing particles from different sources, but also look at how atmospheric processing changes particle toxicity. One main tool I am using in my research are acellular assays, which have been developed as a cell-free alternative to traditional in-vitro methods. The development, testing and evaluation of such acellular assays forms another branch of my research.

If you would like to know more about my research or are interested in joining my group for a thesis project or a research internship, don’t hesitate to send me an email.
