PhD student and researcher at German Research Center for Artificial Intelligence (DFKI) mentored by Volker Markl and Sebastian Breß.

My research interests are data management using modern hardware, and distributed systems. Currently I am investigating automated variant generation from declarative queries for heterogeneous processors.

Before coming to DFKI, I received my MSc degree from ETH Zurich in collaboration with IBM Research, Zurich under supervision of Thomas R. Gross and Animesh Trivedi. My Master's was preceded by an exchange at Imperial College London, where I wrote my BSc thesis under supervision of Peter Pietzuch and Paolo Costa, during my Bachelor's studies at ETH Zurich.
