I studied music and mathematics alongside each other when I was a student. Mathematics won out eventually, but I still play music with orchestras around New Zealand.
My research is concentrated in matroid theory, which is type of abstract geometry. Over the years, I have enjoyed learning more about other fields of mathematics, including computability theory (the study of what computers are capable of doing), complexity theory (the study of what computers are capable of doing efficiently), model theory (the study of what formal languages are capable of expressing), and algebraic number theory.
