MY RESEARCH
My main research interest is to use advanced sensing tools to answer questions in biological, environmental and medical research. Either I use available sensors to address biological questions, or if the needed tools are not available, I develop them.
EXAMPLES OF RESEARCH PROJECTS
From soil to marine biofilms, bacteria drive the cycling of nutrients in the environment. The chemical conditions present determine the processes. With optical sensors I can make those chemical conditions visible in 2D.
IMPORTANT METHODS AND RESULTS
I work on developing and using both optical and electrochemical sensors. A main difference to other labs around the world is that we develop sensors to be functional in complex natural environments and to sense at a high spatial (<100µm) and temporal (<5sec) resolution.
Cooperation and dissemination
COLLABORATION
As a trained chemist working at a Biology department, I collaborate across disciplines every day. I have a strong national and international research network. Furthermore, I collaborate in applied projects with companies within water sensing and treatment.
Teaching
I teach several courses in Microbiology and Microbial Ecology.
Furthermore, I lead the course on Bio-Entrepreneurship at Biologi.

Lastly, I teach at several PhD courses mainly focused on sensor development and application. Those course are typically hands on and very multidisciplinary.
