Abstract
In recent years the notion of biological specificity has attracted significant philosophical attention. This paper focuses on host specificity, a kind of biological specificity that has not yet been discussed by philosophers, and which concerns the extent to which a species is selective in the range of other species it exploits for feeding and/or reproduction. Host specificity is an important notion in ecology, where it plays a variety of theoretical roles. Here I focus on the role of host specificity in biological control, a field of applied ecology that deals with the suppression of pests through the use of living organisms. Examining host specificity and its role in biological control yields several valuable contributions to our understanding of biological specificity. In particular, I argue that host specificity cannot be fully understood in terms of Woodward’s well-known account of causal specificity.

I am Associate Professor in the philosophy department at the Université Bordeaux Montaigne. Previously, I was a postdoctoral researcher in philosophy and psychology in the Concepts and Cognition Lab at UC-Berkeley for the Varieties of Understanding Project, an Assistant Professor at Illinois Wesleyan University, and an Akademischer Rat (roughly equivalent to assistant professor) at the University of Cologne. I received my Ph.D. from Rutgers University in 2014.

My research is in the philosophy of science, and focuses mainly on causation, causal modeling and causal explanation. I am interested in a wide variety of issues concerning causation including causal asymmetries, levels of causal explanation, the causal exclusion problem, the epistemology of causal inference, causal cognition, and causal decision theory. My work also investigates the use of certain causal concepts and assumptions in particular sciences such as biology, epidemiology and medicine.
