I am thankful that I had the opportunity for this Ph.D. project at DTU Physics and am
especially grateful to my main supervisor, Anders Andersen, who I enjoyed working
with and who I learned a lot from. He invested a large amount of his time in my
supervision and was always extremely friendly, patient, and supportive.
I would also like to thank my co-supervisors Thomas Kirboe and Tomas Bohr, who
I had the privilege to work with. I greatly appreciated that Thomas Kirboe always
had our ultimate goals in mind and made sure that my work progressed in the right
direction tackling ecologically important questions. Tomas Bohr is an amazing and
fun person to work with and often saw fascinating questions and details, that I had
previously missed. I had many valuable and interesting discussions with him and felt
very valued by him as a colleague.
In spring 2017 I had the opportunity to spend two months working with Marco
Polin at the University of Warwick. I felt very welcomed in his group and enjoyed his
supervision and our on-going collaboration. The discussions with Marco and Raphael
Jeanneret, who I also would like to thank, were always inspiring, motivating and packed
with valuable wisdom.
I further would like to thank Lasse Tor Nielsen, who I had the pleasure to collaborate
with. I very much enjoyed the discussions I had with him and beneted from his
knowledge on the fascinating biology of our study species. I would also like to thank
him for providing me with images and videos of agellates for various presentations,
papers, and this thesis.
I thank Seyed Saeed Asadzadeh and Jens H. Walther for the collaboration and
discussions on the choanoagellate project.
A further thanks to Kelly R. Sutherland and Keats Conley as well as to Erik Selander
for providing me with images of pelagic tunicates and copepods.
I thank Anders Andersen, Hanna Rademaker, Navish Wadhwa, Tomas Bohr, and
Bettina Dolger for carefully reading drafts and providing helpful feedback on this thesis.
My main workplace was the FLUIDS Section at DTU Physics, but due to my involvement
in the Centre for Ocean Life, I also regularly visited DTU Aqua. Both
workplaces provided a stimulating and friendly atmosphere with many nice and openminded
colleagues, which I highly appreciated.
Finally, I am immeasurably grateful for the continuous encouragement and support
of my family and friends.
