+      A programming language is a very exotic object: it provides a vocabulary
+      to give instructions to a computer, and at the same time, denotes a mathematical
+      object that follows axioms. The purpose of semantics is to reconcile the two
+      notions, giving insights into computation, language design, and programming.
+      In this course, I will introduce some tools and techniques from category
+      theory that are useful to semanticists, and show applications of these to
+      prove fundamental results about type theories and programming languages.
