I am a tenure track assistant professor at RWTH Aachen University. My research deals with the analysis of complex systems that can be abstracted as networks or graphs. A central methodological issue underlying my research is how one can study and integrate the multiple levels of organization which are commonly found in a range of systems. My research combines ‘bottom-up’ dynamical models, and ‘top-down’ data-driven approaches, and uses a blend of tools from control theory, dynamical systems, stochastic processes, machine learning and statistics.

There are PhD and PostDoc positions available in my group. If you are interested, please get in contact.

I studied Electrical Engineering and Information Technology at ETH Zurich with a focus on communication systems. After a MSc in Biomedical Engineering at Imperial College London (Neurotechnology stream), I moved to the Mathematics Department to obtain my PhD under the supervision of Prof. Mauricio Barahona and Prof. Sophia Yaliraki. Following my PhD, I worked in Belgium, jointly at the Université catholique de Louvain and at the University of Namur, as a Postdoctoral Research Fellow. In November 2016, I moved to the Massachusetts Institute of Technology (MIT) as a Postdoctoral Research Associate. From July 2017 onwards I was a Marie Skłodowska Curie Fellow at MIT and the University of Oxford, before joining RWTH Aachen University in June 2020, supported by the NRW Return Programme (2019). I have been awarded an ERC Starting Grant in 2022.
