Christina Vasilakopoulou

I am a mathematician, with interests in Category Theory and Algebra as well as categorical systems modeling.

I am currently an Assistant Professor at the School of Applied Mathematical and Physical Sciences, National Technical University of Athens, Greece.

Earlier, I was a Researcher at University of Patras, a Visiting Assistant Professor at UCR, and a postdoc at ULB, MIT, AUEB and UH Manoa. I obtained my PhD in 2014 at the University of Cambridge, UK.

I am an Editor at Cahiers de topologie et gèomètrie diffèrentielle catègoriques and Theory and Applications of Categories (TAC).
