**About me**

Currently Director of Artificial Intelligence at Helsing, I was a Principal Applied Scientist at Amazon and the Chief Scientist for Amazon SageMaker until June 2023. Since 2017, I am an associate member of the department of Statistics at the University of Oxford. I was elected Fellow in the Robust Machine Learning Program of the European Lab for Learning and Intelligent Systems in 2018. I am Action Editor of the Transactions on Machine Learning Research and regularly serve as Area Chair of top tier conferences in machine learning, such as NeurIPS, ICML, and ICLR.

I received the Electrical Engineering degree and the PhD in Applied Sciences from UCLouvain, respectively in 2001 and 2005. As a member of the Machine Learning Group and the Crypto Group, I worked on the European projects OPTIVIP, in which I developed neural networks embedded in a visual prosthesis for the blind, and SCARD, where I demonstrated weaknesses of cryptographic hardware against machine learning-based side channel attacks that exploit electro-magnetic radiation. Next, I did a Post-doc with John Shawe-Taylor at University College London and collaborated closely with Manfred Opper on problems in data assimilation and approximate Bayesian inference. I was also an active participant of the PASCAL European network of excellence. Until December 2015, I held a Honorary Senior Research Associate position in the Centre for Computational Statistics and Machine Learning.

I joined Xerox Research Centre Europe (now Naver Labs Europe) in October 2009, where I led the Machine Learning group. My team conducted applied research in machine learning, computational statistics and mechanism design, with applications in customer care, transportation and governmental services. I joined Amazon, Berlin, in October 2013 to develop zero-parameter machine learning algorithms. As an Principal Applied Scientist at Amazon Web Services, I oversaw the product-related science powering Amazon SageMaker and lead long-term science initiatives in the area of automated machine learning, continual learning, and responsible AI.

**Open source libraries:**

Syne Tune, a library for asynchronous **hyperparameter and neural architecture optimization**. Our goal is to make machine learning more reproducible by covering a broad range of optimisers, offering multi-fidelity and multi-objective algorithms, and making it easy to run experiments on the cloud. We just released a new version with better documentation!

Renate, a **continual learning** library to automatically retrain and retune deep neural networks!

Fortuna, a library for **uncertainty quantification** to help deploy deep learning in a more responsibly and safely!
