Liana Heuberger

My research is in birational geometry and toric geometry, specifically finding Fano varieties of dimension up to four which are either smooth or have mild singularities. A useful tool in achieving this is the combinatorics of polytopes, reflecting the geometry of (possibly very singular) toric varieties they correspond to. My aim is to construct an explicit (partial) smoothing of these objects in order to obtain a Fano variety. I'm also interested in moduli spaces of quiver representations, quiver flag varieties and the McKay correspondence.
