Curriculum Vitae: Alexandra Nauditt

Alexandra Nauditt (PhD, MSc, BSc) is an environmental scientist and lecturer with a focus on hydrology, drought, land and water management. Since her start at ITT in 1999, she has coordinated a large number of educational and research projects with a regional focus on Latin America and South East Asia as the BMBF funded research projects “Land Use and Climate Change Interactions in Central Vietnam – LUCCi” ( and “Water Use Efficiency in Semi-Arid Central Chile” (

She is a graduate from the University of Aberdeen and holds a PhD in Hydrology and an MSc in Earth Sciences. Currently her research is focussing on hydrological drought risk assessment and management in data scarce semi-arid and tropical regions.
