Hrund Ólöf Andradóttir is a Professor in the Faculty of Civil and Environmental Engineering within the School of Engineering and Natural Sciences at the University of Iceland. She earned her Ph.D. in Civil and Environmental Engineering from the Massachusetts Institute of Technology in 2000, an M.Sc. in the same field from MIT in 1997, and a C.Sc. (Candidatus Scientiarum) in Civil Engineering from the University of Iceland in 1994. Her career includes serving as Associate Professor at the University of Iceland since 2006 and as Senior Consultant and Consultant at Mars & Co. in Greenwich, CT, USA, from 2001 to 2006. She currently teaches courses such as The Engineering Profession and Responsibility of Engineers (UMV102G), Environmental Engineering G (UMV302G), and Water Quality (UMV121F).
Her research specializations encompass sustainable built environment, water quality, air quality, physical limnology, and cold climate processes. Key collaborations include projects on sustainable urban drainage in cold climates with Lund Technical University, air quality in Reykjavík with the University of Colorado Denver, and physical processes in sub-Arctic lakes with the University of Granada. Notable publications include 'Assessment of flood hazard in a combined sewer system in Reykjavik city centre' (2015, cited by 52), 'Microbial contamination in groundwater supply in a cold climate and coarse soil: case study of norovirus outbreak at Lake Mývatn, Iceland' (2013, cited by 37), 'Constructed wetlands with recycled concrete for wastewater treatment in cold climate: Performance and life cycle assessment' (2023, cited by 34), 'Spatial distribution of hydrogen sulfide from two geothermal power plants in complex terrain' (2014, cited by 33), and 'Status of small water supplies in the Nordic countries: Characteristics, water quality and challenges' (2017, cited by 32). Recent works address PFAS in Icelandic waters (2025), domestic wastewater treatment in the Arctic (2025), black carbon during rush-hour traffic (2024), impacts of wildfires on drinking water catchments (2024), and climate change effects on winter flood mechanisms (2024). Her scholarship, with over 50 research outputs and contributions to environmental challenges in cold climates, underscores her impact in the field.
