Timo Houben

Timo Houben is a Geoscientist, Data Scientist, and Modeller working in the Department of Monitoring and Exploration Technologies at the Helmholtz Centre for Environmental Research - UFZ in Leipzig, Germany. His work focuses on environmental data science, machine learning applications for environmental monitoring, and groundwater modeling. He is actively involved in several research projects including AIAMO (Artificial Intelligence and Mobility) and has contributed to developing tools for urban air quality monitoring and soil moisture prediction.

Houben holds a Ph.D. in Groundwater Modeling from the Helmholtz Centre for Environmental Research - UFZ (2017-2020), supervised by Sabine Attinger. Prior to this, he earned a Master of Science in Applied Geosciences with a focus on Engineering Geology, Hydrogeology and Geophysics from RWTH Aachen University (2013-2016), and a Bachelor of Science in Applied Geosciences from the same institution (2009-2013).

Houben's research spans multiple interdisciplinary areas at the intersection of environmental science and data science. His primary interests include urban small-scale air quality monitoring and modeling, AI and high-performance computing applications for environmental problems, and machine learning for automated quality control of environmental sensor data. He has developed expertise in spectral analysis of environmental signals, particularly for groundwater level fluctuations, and has created Python tools for aquifer characterization. His work bridges theoretical modeling with practical applications for environmental monitoring and management.

His recent publications demonstrate a strong trend toward integrating machine learning with environmental monitoring systems. Houben has made significant contributions to spectral analysis methods for groundwater parameter estimation, urban air quality monitoring through digital twin technology, and machine learning applications for soil moisture prediction. His work increasingly focuses on explainable AI methods for environmental applications, particularly for quality control of sparse sensor networks. The interdisciplinary nature of his research connects hydrogeology, data science, and urban environmental management.

Houben is actively involved in several research teams and projects. He co-chairs the PhD-Team Data Science at UFZ and previously chaired the Machine Learning Café. His current work with the AIAMO project focuses on developing an urban digital twin for environmentally sensitive mobility planning in Leipzig. He has contributed to the development of AquiPy, a Python tool for aquifer characterization, and has been involved in spectral analysis of groundwater level fluctuations to estimate hydrogeological parameters.
