Stefano Bonaglia

Stefano Bonaglia serves as Associate Senior Lecturer in the Department of Marine Sciences at the University of Gothenburg, where he investigates human impacts on aquatic biogeochemical cycles through integrated field, laboratory, and molecular approaches. His research spans coastal and marine environments globally, with emphasis on greenhouse gas dynamics and sediment-water interactions.

Dr. Bonaglia's primary focus lies in marine biogeochemistry, particularly nitrous oxide and methane cycling in fjords, lagoons, and aquaculture systems. He examines how eutrophication, climate change, and biological processes regulate greenhouse gas emissions using isotope tracers, microsensors, and advanced analytical techniques (GC-IRMS, HPLC-ESI-MS/MS). His work bridges geochemistry and microbial ecology to identify key transformation processes in coastal sediments.

Analysis of his recent publications reveals consistent emphasis on anthropogenic impacts on coastal biogeochemistry, with growing integration of molecular methods to link microbial communities with greenhouse gas production. His research spans diverse systems from Arctic shelves to tropical mangroves, highlighting universal principles in nutrient cycling while addressing region-specific challenges.

Dr. Bonaglia actively mentors early-career researchers and secures competitive funding for critical environmental research:

• Current Projects: VR-funded study on fjord greenhouse gas dynamics; Formas project quantifying mussel farming emissions
• Students: PhD candidates Lok Shan Cheung (nitrogen cycling) and Lea Loraine Ropella (aquaculture emissions); Postdoc Tobia Politi (fjord biogeochemistry)
• Teaching: Courses in Chemical Dynamics in the Sea (MAR450), Environmental Chemistry (KEM490), and World Oceans (MAV112)

His laboratory at Medicinaregatan 7B employs cutting-edge instrumentation for sediment and water analysis, supporting collaborative field campaigns across Europe and the Arctic. The group maintains strong international partnerships while addressing urgent questions about coastal climate feedbacks and pollution impacts.
