Dr Julien Herrero
Postdoctoral Researcher
McGill University - Department of Mining, Metals and Materials Engineering

A kernel mean embedding method for high-order geostatistical simulation in orebody modelling

11:55 AM - 12:20 PM

Biography

Julien Herrero is a postdoctoral fellow in the COSMO lab at McGill University working in geostatistics, and more specifically on the development of new orebody modeling methods. He is currently working on kernel methods to produce a new high-order geostatistical simulation workflow. His research also focuses on probabilistic inverse problems, Bayesian methods, and uncertainty quantification for subsurface modeling. With a background in geostatistics, geophysics, and reservoir engineering, he developed approaches such as transdimensional MCMC during his PhD thesis (Nancy school of Geology, France, 2022-2025) to better characterize geological structures and their uncertainties. This work aims to improve the reliability of subsurface models for applications in geosciences and energy.
