My philosophical research is about scientific methodology, in particular how scientists build mathematical models to acquire knowledge about complex systems in the world, and its relation to policy. Typical questions I am interested in exploring are: How do scientists choose and identify phenomena of interest? What kind of assumptions are used to build models of phenomena, and how are they justified? Do these justifications change depending on whom these models provide information for, and if yes, how?

I am particularly interested in exploring these questions in the context of climate change research. My dissertation, for example, draws from case studies in atmospheric science and oceanography to illustrate the challenges that are tied to identifying phenomena, and what kind of assumptions are made in the process of isolating target systems from their environment. I am currently developing an interdisciplinary (history&philosophy of science and social science) research proposal that extends these questions to the distinction between weather and climate and its epistemological and social implications for current efforts to build so-called “seamless prediction” models.

I am also interested in the social and political aspects of climate science, such as issues at the intersection of epistemology, environmental ethics and public policy. At the University of Leeds, for example, I am working with an interdisciplinary research group from the Center for Climate Change Economics and Policy on developing a conceptual framework to analyze the quality of climate information for adaptation. This framework draws on insights from philosophy of science, environmental social science and physical climate science. I also recently joined a project that develops climate risk storylines to explore the remote impacts of climate change on Europe.
