# Christer Borell

Professor emeritus, Mathematical Sciences

During my 48 years as a teacher at various universities I have lectured a variety of courses at different levels. Since 1997 most courses have been in financial mathematics. My research has always been motivated by different problems in convex geometry often in infinitely many space dimensions.
