Abstract: The rational homotopy groups of the group Diff(S^4) of self-diffeomorphisms of S^4 with the C^\infty-topology. We present a method to prove that there are many 'exotic' non-trivial elements in the rational homotopy groups of Diff(S^4) parametrized by trivalent graphs. The proof utilizes Kontsevich's characteristic classes for smooth disk bundles and a version of clasper surgery for families. In fact, these are analogues of Chern-Simons perturbation theory in 3-dimension and clasper theory due to Goussarov and Habiro.

Title: "JTbar deformed CFT2 and string theory"
 

When developing a drug, biomarker, or treatment approach, how will it actually work in patients, and how will it change the decisions that are made during treatment? Doctors, patients, and other stake holders each have different concerns about the costs/benefits at each stage of a medical treatment, and these concerns are not always effectively met. We focus on these issues in a teaching setting at Brown University (USA) as a lot of the tools for translating research into healthcare are generally relevant to how we do collaborative research.
