Biography
Since November 2018 I am an academic in the School of Computer Science and Informatics. From November 2016 - October 2018, I was an EU's H2020 Marie Skłodowska-Curie Fellow within the Sêr Cymru II programme.
Before Cardiff
Before joining Cardiff University, I worked for two years as postdoctoral researcher at the University of Bremen in the Theory of Artificial Intelligence Group led by Carsten Lutz. From September 2013 to January 2014, I worked at the University of Liverpool as research assistant with Frank Wolter and Boris Konev.
In November 2013, I got my PhD at the University of Bremen under the supervision of Carsten Lutz. I obtained a MSc in Computational Logic from TU Dresden in 2009.
