**Dr. Phillip Morenz** presented "Convexity/non-commutative convexity". In two hours he showed how research mathematics is actually done, starting with a straightforward, intuitive concept (convexity), and showing how this concept gets generalized mathematically into something much more complex, and much less intuitive (non-commutative convexity).
