About

I have a masters degree in mathematics with specialization in algebra, number theory and lattice algorithms, and I have a PhD in computer science specialized in k-shortest path algorithms.

Now I'm a Postdoc in algorithm engineering at Goethe University Frankfurt.

I'm also the developer of Sephpa and SepaUtilities, two PHP libraries to generate SEPA files.
