Dr. Expert studied Physics (BSc and MSc) and then Statistics (MSc) at the University of Geneva and received his PhD in Physics from Imperial College London in the Complexity and Networks Group under the supervision of Prof. Kim Christensen. His thesis work made use of statistical mechanics and complex network approaches to study various systems from the human brain to human interactions.
As a post doctoral researcher with Prof. Federico Turkheimer in the Center for Neuroimaging Sciences at King's College London, he continued to develop novel network based analysis methods and pioneered the use of persistent homology approaches to characterise altered states of consciousness.
He then came back to Imperial to join the EPSRC Centre for Mathematics of Precision Healthcare (CMPH), to work with Prof. Mauricio Barahona to develop graph spectral based methods in machine learning and persistent homology and his own line of research in temporal graph signal analysis.
He is currently part of the Global Digital Health Unit, at Imperial College London, where he uses topology based methods to represent and analyse Electronic Health Records to map patient movements in hospital and computational epidemiology approaches to propose mitigation strategies against nosocomial infections spreading in general and covid-19 in particular. He is also interested characterising the space of patient clinical trajectories extracted from Electronic Health Records to help predict patient deterioration and outcomes.
I am extremely excited to join the World Research Hub Institute and collaborate with Prof Takayasu Misako on human mobility and epidemiology problems. The new Risk Management of
Complex Systems Satellite Lab is a timely addition to WRHI and brings together world leading scientists in complex systems and champions the fundamentally interdisciplinary approach to societal problems that I am passionate about. I have a long history of collaborations with Japanese researchers and I’m convinced this appointment will be an opportunity to strengthen existing collaborations and create new ones.
