[2] Born on 28 October 1960, in Requena, Spain, Gómez-Hérnandez earned his Civil Engineering Bachelor's degree from the Technical University of Valencia in 1983.

[3] 30 years later, he would supervise several PhD theses and publish a number of important papers on the use of the ensemble Kalman filter for inverse modeling in aquifers.

His research can also be grouped into the following four main subjects: Gómez-Hernández developed for his PhD a stochastic simulation technique for random functions that was much more precise and versatile than other contemporary codes, and, more importantly, without limitations on the size of the realizations to be generated.

Gómez-Hernández proposed a paradigm shift in describing how the parameters that control groundwater flow and solute transport are spatially distributed in the subsurface.

In 1992, as a member of the INTRAVAL project—financed by a pool of nuclear waste management agencies—whose objective was the validation of codes for flow and transport in the subsurface, he detected a serious error in the simulation of scenarios of failure.

A number of his more recent papers demonstrate the applicability of the ensemble Kalman filter to this task, of which a seminal one is the 2011 article, "An approach to handling non-Gaussianity on parameters".
