Robert Penner is studying geometric topological problems                   with implications for particle physics.  There is a highly                      developed, essentially combinatorial, theory of conformal classes               of punctured Riemann surfaces.  Some recent work at once suggests               new approaches to old problems in the Teichmuller theory and in                 the theory of the mapping class group.  Furthermore, there is a                 great deal of interplay between these new results and several                   central problems in the string theory of high energy physics.                   This second interface should probably be regarded as one of co-                 development rather than one of application.
