About 

I am a second year PhD candidate under the supervision of Eiko Yoneki. Prior to starting my PhD, I completed an MPhil in Advanced Computer Science in Cambridge as well as a Bachelor's degree at the University of Hamburg, Germany. My PhD is on data processing aspects and systems applications of deep reinforcement learning. In particular, I am interested in providing controllers for runtime configurations in distributed systems with as little manual modelling as possible. Complementary to this, I am also working on applications of iterative optimisation (see our work on structured Bayesian optimisation) in computer systems where full control is unnecessary or impractical. Previously, I have worked on cloud infrastructure for real time caching with baqend (see our joint paper at VLDB 2017).
