Research Interests
Intersection of logic and mathematics; (Applied) proof theory, in particular I have been working on proof mining (extraction of computable bounds from mathematical proofs) applied to proofs in nonlinear analysis, differential equations and fixed point theory); Foundations of mathematics.
My Erdös number is 4 (Erdös ->Magidor ->Bagaria ->Kohlenbach ->K.-A.).
Studies
PhD (Dr. rer. nat.), Department of Mathematics , Technische Universität Darmstadt. The defense of my PhD thesis entitled ''Proof Mining for Nonlinear Operator Theory: Four Case Studies on Accretive Operators, the Cauchy Problem and Nonexpansive Semigroups'' under supervision of Prof. Dr. Ulrich Kohlenbach and funded by the International Research Training Group 1529 (Oct. 2013- Sept. 2016) took place on Dec. 21, 2016.
I previously obtained a M.Sc. in Mathematics from the Department of Mathematical Sciences, University of Copenhagen, Denmark (Dec. 2012), a Master de Sciences et Technologies (Mention Physique et Applications) from Université Paris VI (Pierre et Marie Curie), France, and a Diploma from the School of Applied Mathematical and Physical Sciences , National Technical University of Athens , Greece (2009).

Other
- Member of the organising committee of the conference ''PhDs in Logic VIII'' (TU Darmstadt, 9-11 May 2016).
- Research stay at Waseda University, Tokyo, Japan (1/9/2014-10/3/2015) hosted by the Analysis Research group, in connection to the IRTG 1529 . During this time also very briefly visited the Sendai Logic group of Tohoku University and JAIST in Kanazawa.
- Member of the Association of Symbolic Logic and of the DVMLG.
- Doktorandentreff: (usually) every second Thursday, the PhD students of our logic research group hold a casual meeting to discuss current research or any fun topic in logic. This usually involves an afternoon social event/dinner followed by an evening informal blackboard presentation. Interested students (e.g. Master/visiting students) who would also like to be in the mailing list are most welcome to email me.
