Ezra Haaf

Researcher at Geology and Geotechnics

Ezra is a researcher at the division for Geology and Geotechnics within the research group Engineering Geology. His research focuses on development of data-driven and hybrid (combined numerical and data-driven) methods for efficient and risk-based modelling in hydrogeology and engineering geology. The aim is sustainable management of groundwater-related issues on regional and local scales. Main research questions are (i) spatial and temporal predictions of risks in data scarce regions for regional groundwater management, and (ii) analysis and attribution of groundwater impacts in infrastructure projects.
