System Conceptualisation

Applied geological fields, such as water resource assessment or environmental impact assessment, requires bringing together vast amounts of very diverse data in a way that is consistent with our ever evolving understanding of the earth. My research within Deep Earth Imaging explores the different ways we can conceptualise geological systems and how we can systematically test hypotheses about subsurface processes. The application of this research is mainly focused on groundwater investigations.

With over 7 years research experience in modelling groundwater dynamics at regional to continental scales for water resource management, I bring an understanding of water systems to Deep Earth Imaging. My research features a strong emphasis on maximally exploiting the information from data to reduce predictive uncertainty. I have an actively open mindset in combination with an insatiable thirst for knowledge. This helps me champion interdisciplinary research, bringing together geology, geophysics, geochemistry, statistics, hydrology, ecology and risk assessment to address the nation’s grand challenges in finding and managing groundwater.

Technical Skills

I have deep professional and academic experience in the following areas:

  • Risk and uncertainty analysis
  • Groundwater and surface water modelling
  • Geostatistics, exploratory data analysis and machine learning
