About me

I am a postdoc in the Faculty of Informatics at the University of Lugano, working with Kai Hormann. I received my PhD from the Computer Laboratory, part of the University of Cambridge.

I have a curriculum vitae available online.

Research

My research currently surrounds geometry processing and its applications, particularly subdivision surfaces. My PhD thesis, NURBS-compatible subdivision surfaces, developed the first subdivision extension of NURBS surfaces.
