Majken Caroline Looms Zibar is an Associate Professor in the Department of Geosciences and Natural Resource Management at the University of Copenhagen's Faculty of Science. Her research focuses on applying advanced geophysical methods to solve hydrological problems, particularly in the unsaturated zone. She has established herself as a leading expert in ground penetrating radar applications for subsurface characterization. Her research interests span multiple areas of hydrogeophysics including cross-borehole electrical resistance tomography, ground penetrating radar applications, and cosmic-ray neutron detection. Dr. Looms Zibar specializes in visualizing water infiltration in unsaturated zones, estimating unsaturated hydraulic parameters at meter-scale, characterizing porosity variations in geological formations, and monitoring soil moisture dynamics. Her work bridges geophysics and hydrology to address critical water resource management challenges. Analysis of her recent publications reveals a strong focus on advancing geophysical methods for environmental applications, particularly in soil moisture monitoring using novel approaches like cosmic-ray neutron sensing and gamma-ray spectrometry. Her research increasingly integrates multiple geophysical techniques to characterize subsurface heterogeneity across different spatial scales, with growing emphasis on agricultural applications and water resource management. Appointed member of Hydrology Section's Hydrogeophysics Technical Committee under the American Geophysical Union since 2011 Associate Editor of Vadose Zone Journal from 2014-2019 Principal organizer of the 5th International COSMOS workshop in Copenhagen in 2016 Dr. Looms Zibar has secured significant research funding, including projects funded by Geocenter Denmark, Region Hovedstaden, and international programs like Marie Curie Innovative Training Networks. She has supervised 21 Bachelor's projects, 15 Master's theses, and 8 PhD dissertations, while serving on 8 external PhD assessment committees. Her research group actively collaborates with institutions across Europe and maintains strong connections with water management authorities in Denmark. Her laboratory work focuses on developing and refining cross-borehole geophysical methods, particularly ground penetrating radar applications for challenging geological environments like clayey tills. The research group maintains field sites for long-term monitoring of hydrological processes and has developed specialized equipment for environmental geophysics applications, including novel crosshole GPR systems and gamma-ray spectrometry setups.
