I am a Postdoc at the Institute of Differential Geometry, Leibniz University Hannover. Contact information can be found here.
My research is concerned with inverse problems and geometry, with tools mainly coming from (singular) microlocal analysis. In my thesis I studied the X-ray transform in the setting of asymptotically hyperbolic manifolds, whereas more recently I have been working on inverse problems for hyperbolic equations. I am also interested in interplays between the geodesic X-ray transform on closed manifolds and higher Teichmüller theory. More recently I have been working on questions regarding the range of the X-ray transform on hyperbolic space.
