Stefano Bonaglia
Associate Senior Lecturer
Department of Marine SciencesAbout Stefano Bonaglia
Our coasts and ocean are changing due to direct and indirect effects of human activities. My main interest is to understand how ecological factors and human processes influence aquatic biogeochemical cycles. I tend to combine sea expeditions; water/sediment sampling using a vast array of devices; deployment of in situ landers; lab micro- and mesocosm experiments and incubations.
I enjoy using isotope tracers, microsensors, optodes, and other analytical techniques such as GCs, GC-IRMS, ICPs, HPLC-ESI-MS/MS, SEM. In concert with my scientific network, we complement geochemistry with molecular biology to better understand biogeochemical transformation processes and their microbial key players.
Currently, I have two projects funded by VR and Formas dealing with greenhouse gas (GHG) exchange in fjords and GHG emissions from mussel farming, respectively. Read more here:

At the Department of Marine Sciences, University of Gothenburg, I lecture for courses:
- Environmental Chemistry (KEM490)
- Chemical Dynamics in the Sea (MAR450)
- Världshaven och djupa sediment (MAV112)
My lab at Gothenburg consists of:
- PhD Student Adele Maciute - Project aimed at investigating the role of meiofauna on vital ecosystem processes
- PhD Student Lok Shan Cheung - Project dealing with nitrogen loss and gain in the marine environment
- Postdoc Tobia Politi - Working on greenhouse gas exchange in fjords, funded by my VR project
- MSCA Postdoc Tetyana Gilevska - 2-y Marie Curie project on contaminated sediments and methanogenesis
