New PhD student in Freshwater Ecology

I am Edevardt Danielsen. I come from northern Norway and is a PhD student. I am particularly interested in how aquatic ecosystems contribute to greenhouse gas emissions, with focus on the interactions between biogeochemical processes, submerged macrophytes and the oxygen dynamics shaping these fluxes. My work allows me to spend time both outdoors, conducting fieldwork, and indoors in the lab.

What do you like about working in Denmark?
I love the campus life here in Aarhus. The infrastructure and living environment are quite different from what I am used to, and it creates a great atmosphere for both work and daily life. AU provides an excellent research environment, with strong collaboration between scientists, and offers world-class facilities for freshwater ecology studies. The balance between independent research and teamwork makes AU a stimulating and supportive place for scientific development. Being part of the Sino-Danish Center for Education and Research (SDC) is particularly valuable, as it allows me to integrate research perspectives from both Denmark and China, strengthening my ability to work across diverse scientific and cultural settings.

What is your focus of research?
My research focuses on greenhouse gas emissions from freshwater systems, particularly how submerged macrophytes and oxygen dynamics influence methane and carbon dioxide fluxes in lakes. Using a combination of field sampling and mesocosm experiments, I aim to understand the role of aquatic ecosystems in carbon cycling. Working in both Denmark and China enables me to compare greenhouse gas emissions across different environments and assess how macrophytes and oxygen conditions shape these processes.

What has inspired you to choose freshwater science?
Lakes are dynamic systems where physical, chemical and biological factors intertwine, driving greenhouse gas emissions in ways that we are still unraveling. My passion for this field increased during my Master’s thesis when I spent a year in Nanjing, China, studying greenhouse gas emissions from Xuanwu Lake. That experience opened my eyes to the critical role that freshwater ecosystems play in the global carbon cycling and their direct link to climate change and ecosystem management. It sparked a curiosity that has since fueled my pursuit of a research path to deepen our understanding of these complex interactions.

What are your dreams for your working future?
As part of SDC, I am already working in an international research environment, which I believe provides a strong foundation for my future career. Moving forward, I hope to strengthen global collaborations and contribute to a deeper understanding of greenhouse gas dynamics in freshwater ecosystems. My goal is to apply this knowledge to improve climate models and develop effective mitigation strategies. Ideally, I want to be in a position where I can combine field research, advanced analytical techniques and international cooperation to tackle key environmental challenges related to freshwater ecosystems and climate change.
