I am an organic geochemist studying how humans, climate, and the environment interact with each other. I use fossil molecules (known as biomarkers) preserved in sediment to learn about past climate change and human activities, mostly focused on the past 2000 years. My work takes me to remote sites in the tropical Pacific, as well as to lakes closer to home in Switzerland. I also investigate the ways plants and algae incorporate information about the environment into their lipid biomarkers today, so that we can use their molecular remains to better reconstruct past change.
