Dr. Javier Vilcáez, Associate Professor

My current research is on the Water-Energy-CO2 nexus. I conduct experimental and computational research on the petrophysical characterization of rocks, as well as on the hydrological, geochemical, and microbiological factors and interactions that control the multiphase bio-geochemical reactive transport of gas, aqueous, and hydrocarbon compounds in deep and shallow geological formations of complex heterogeneous porous media such as carbonates, at both the pore- and field-scale levels. The  focus is on groundwater quality, petroleum produced water treatment and disposal, geological carbon storage and utilization, and  enhanced oil recovery in the form of methane and hydrogen. The goal is to develop new environmental technologies and computational methodologies to minimize the environmental burden of and optimize the development of subsurface energy and groundwater resources. My research incorporates the utilization of global optimization, machine learning, and environmental data analytical tools and techniques.

So far, my research has resulted in more than 40 peer-reviewed articles published in energy, mineral, environmental, and groundwater journals. I value independence, the majority of my publications are as first and/or corresponding author of research done by myself and with undergraduate and graduate students working under my supervision.
