Nicolas successfully defends his PhD research

Nicolas (Walpen) successfully defends his PhD research! His PhD research focussed on the redox properties and dynamics of dissolved and particulate organic matter from Northern Peatlands. He was the first PhD student in the Sander group to have complemented laboratory analyses with work in ombrotrophic bogs in Värmland, Sweden.
On the left you can see Nicolas with Rose Cory, who was the external reviewer of Nicola's PhD work, competing in what we refer to as the real PhD defense. Thanks, Rose, for being on the committee and helping to challenge Nicolas during the defense. He did great!

Congratulations, Nicolas ...
... excuse me: Dr. Walpen !
