Steering Committee

The present structure of the network consists of a Steering Committee, led by a Chairperson and two Co-chairs and Task Teams supported by a Advisory Team formed by previous chair and co-chairs of the network.

To ensure active participation of the ECHN steering committee, members are invited to join the committee for one year as part of the task teams. Following this time, members can reapply if able to continue involvement.

Membership of the steering committee should not be automatically renewed to allow for new member involvement, changing priorities of existing members and also reflect that involvement may be task specific or due to geographical location, e.g. assisting in a specific annual IAH congresses organizing committee.

Jared van Rooyen


Jared is a PhD candidate from Stellenbosch University (South Africa), his research is focused on the use of isotopic geochemistry in the investigation of regional groundwater resources with specific focus on modern groundwater distribution and groundwater vulnerability to climate change.


Raquel Sousa

Her focus is on groundwater chemistry, specifically looking into the application of stable and radioactive isotopes to better understand groundwater systems in Southern Mozambique.


Richard Hoffman

Task team, BELGIUM

Richard works as PhD researcher at Liège University in Belgium. His work is focus on sustainable groundwater management and efficient heterogeneity uncertainty quantification. He applies joint tracer tests in conjunction with innovative multiple scale transport modelling. He holds a MSc in Applied Geosciences from the RWTH Aachen University in Germany with specification in Hydrogeology, Geophysics and Engineering Geology.


Luis Camilo Suescún

Task team, COLOMBIA

Luis Camilo holds a bachelor’s degree in Civil Engineering and MSc. in Water Resources from National University of Colombia where he obtained a Laureated thesis and international awards. His research was focused on analytic and numerical inverse modeling to estimate seepage flows in deep tunnels. He is currently working as Groundwater modeler in DHI Group developing groundwater flow and transport models in fractured and porous media for underground and mining projects in Latin America. He is representative of IAH-Colombian Chapter and supports the ECH’s expansion in Colombia as a volunteer in activities related to oil&gas industry, water management and transfer groundwater knowledge. His principal interests are Groundwater Modeling, Groundwater Management, Groundwater Quality, Groundwater Governance, and Socio-Hydrogeology.


Antonia Genot

Task team, CHILE

Antonia is a MSc candidate at the University of Chile, Santiago, Chile and now working in Itasca Chile Spa (belonging to Itasca International Inc.). Her research focused on water-rocks interaction, mainly with peridotites, to perform a hydrogeochemical exploration and study potential contamination associated with this interaction. Her main interests are hydrochemistry, water contamination and groundwater management.
