Jeffrey Danciger (jdanciger@math.utexas.edu): Research interests include geometry, topology, and deformation theory of locally homogeneous geometric structures on manifolds.
John E. Luecke (luecke@math.utexas.edu): Research interests include the topology and geometry of 3-manifolds, applications of topology to biology and the knotting of DNA.
Michael P. Starbird (starbird@math.utexas.edu): Research interests include low dimensional geometric topology and topics in mathematics education - particularly how to make mathematics accessible to the general public.
