Curriculum Vitae

In September 2012, I received my Master’s degree in Computer Science with honors from Technische Universität Darmstadt, where I was fortunate to work on my Master-Thesis “Limitations of the Meta-Reduction Technique: The Case of Schnorr Signatures” under my Advisor Marc Fischlin. The results of my thesis were published at Eurocrypt 2013. Between July and October 2013, I was given the amazing opportunity to spend the summer on a research visit at University of Maryland, College Park. There I was very fortunate to work with Jonathan Katz and Dana Dachmann-Soled. Between July and September I was fortunate to work with Christina Brzuska as a Research Intern at Microsoft Research Cambridge.
