About Me

I am a postdoc at the Zuse Institute Berlin (ZIB) in the IOL group, where I work with Sebastian Pokutta among others. Prior to this, I was a PhD student at the Department of Computer Science at the University of Oxford supervised by Prof. Varun Kanade and Prof. Patrick Rebeschini. I obtained an MSc in Mathematics and Foundations of Computer Sience at the University of Oxford and a double Bachelor in Mathematics and in Computer Science at the Complutense University of Madrid.

Research

I am interested in continuous optimization and fields that interplay with it, like online learning and statistical machine learning. My focus is on high-dimensional problems appearing in machine learning, and network analysis, among others. Some topics I have worked on are Riemannian geodesically-convex optimization [1, 2, 3], fair-packing [4], PageRank [5], and bandit problems [6].
