Charlie SIRE


I am a Postdoctoral researcher at Mines Paris at the Centre for geosciences and geoengineering, under the supervision of Mike Pereira and Thomas Romary. My Ph.D thesis was defended at IRSN and was supervised by Rodolphe Le Riche and Didier Rullière. Here is my CV.

Research interests

I work on uncertainty quantification in the context of expensive-to-evaluate simulators and spatio-temporal statistics. My research is primarily based on Gaussian Processes, applied to various challenges such as quantization, optimization, design of experiments, Bayesian calibration, and SPDE-based approaches.
