Career Development Fellow in Philosophy at Christ Church, University of Oxford
Welcome to my website! I am a Career Development Fellow in Philosophy at Christ Church, University of Oxford. At Christ Church, I am also the Director of Studies for the undergraduate degrees Mathematics & Philosophy, Computer Science & Philosophy and Psychology, Philosophy & Linguistics.
I did a DPhil (that is, PhD) in Philosophy at the University of Oxford, where I worked under the supervision of Prof Alexander Paseau, Prof Volker Halbach and Dr Wesley Wrigley on a thesis titled 'Neo-Logicism and Gödelian Incompleteness'.
Research Interests
My research is situated at the intersection of logic with adjacent disciplines such as philosophy of mathematics, philosophy of science, epistemology and computer science. I believe many questions of philosophical interest arise here.
