When asking Kaja for her nationality it is "European". Being half German and half Polish and after having lived in many different places it is hard for her to decide for a single one. She moved to Brussels in the beginning of November 2016 to become a part of the Bubble. Although she has studied European studies and Public Policy, her other big interest is: food - a hobby she shares on her blog 'The Recipe Suitcase', where she writes either about food prepared by herself or recommending one of the many restaurants she visits around Europe.
