👋 About

I am a research scientist at the German Aerospace Center (DLR) and a final-year PhD candidate in Computing at Newcastle University in the United Kingdom. Within the university, I am part of the Cloud Computing for Big Data CDT and the Fluid Dynamics Lab.

My PhD research focuses on computer emulators and the optimisation of physical experiments and computer simulators. I am also developing NUBO, a transparent Bayesian optimisation package in Python, with the aim of making the optimisation of expensive-to-evaluate black-box functions accessible to researchers from all disciplines. An open-source version is available here.
