I am Wissenschaftlicher Mitarbeiter in Philosophy at the University of Hamburg. I work primarily in metaphysics and the philosophy of science, and I have further research interests in logic, the philosophy of physics and the philosophy of language. I also have teaching interests in the history of philosophy.

I received my BA summa cum laude in mathematics and philosophy from Yale University and my PhD in philosophy from New York University, where my advisor was Kit Fine. I have also held positions at the National Autonomous University of Mexico (UNAM) and at the University of North Carolina at Chapel Hill, where I worked with L. A. Paul on a project funded by the John Templeton Foundation.
