Inge Rörig-Dalgaard

Inge Rörig-Dalgaard is a Senior Researcher at the Department of Environmental and Resource Engineering, Materials & Durability, Technical University of Denmark (DTU). Her expertise focuses on building material durability, particularly electrochemical desalination techniques for medieval masonry conservation and salt-damage mitigation in fired clay bricks.

Her research spans desalination (100% fingerprint weight), building materials (71%), electrochemical desalination (61%), and electromigration (61%), with significant work on clay bricks (56%) and brick masonry (47%). She investigates moisture transport, relative humidity effects, and electric field applications to develop sustainable conservation strategies for cultural heritage structures.

Recent publications demonstrate experimental rigor in medieval plaster analysis, mortar identification, and salt-crystallization testing. These reflect converging trends in electrochemical conservation methods, accelerated durability assessment, and climate-resilient heritage preservation.

Dr. Rörig-Dalgaard actively supervises two PhD candidates: R. Stenholt-Jacobsen (lime mortars for brick reuse, 2023-2027) and J. Bartholdy (hydrogel desalination of wall paintings, 2021-2025). Her research is supported by DTU-funded projects and international collaborations through RILEM technical committees.

She operates within DTU's Materials & Durability research group, utilizing advanced electromigration setups and hydrogel application systems for non-invasive conservation. Current work focuses on scaling lab-developed desalination protocols for real-world heritage sites while optimizing brick-reuse methodologies.
