I received my Ph.D. from the University of Liverpool in 2011; my supervisor was  Toby HallI visited Georgia Tech between  2014-2015  as  a  postdoc under the supervision of Dan Margalit. I have been an assistant professor of mathematics at Dicle University since 2012. Here is my CV.


  • Research Interests: Low dimensional topology, mapping class groups, topological dynamical systems; in particular dynamics of surface homeomorphisms and algorithms for multicurves on surfaces via global coordinates  such as train tracks, Dynnikov coordinates, Dehn-Thurston coordinates.
