Curriculum Vitae: Dr. Alexandra Nauditt

Alexandra Nauditt (PhD, MSc, BSc) is a senior scientist focusing on research and postgraduate education related to drought risk, hydrology, water management, the Water-Food-Energy Security Nexus and the development of related site tailored data sets for data scarce regions.
Since her start at ITT in 1999, she has been coordinating international and interdisciplinary projects, among them the BMBF funded research projects “Land Use and Climate Change Interactions in Central Vietnam – LUCCi” ( and “Water Use Efficiency in Semi-Arid Central Chile” (
Currently she works on interdisciplinary approaches to assess and project drought risk and tradeoffs related to the Water-Energy-Food-Security Nexus in data scarce semi-arid and tropical regions, like addressed in the ADAPTA project (, WaterSec and TropiSeca (
