Acknowledgements

In closing, I would like to express my gratitude to all the people without whose support this thesis would not have been possible.

First of all, I am grateful for the opportunity to do my PhD research at Leiden Obser- vatory. The Observatory has a stimulating and professional atmosphere, with a steady stream of visitors, new students, PhDs, postdocs (and even staff) to learn from and share ideas with. A special thank you to the staff who keep the Observatory running so smoothly, especially throughout our recent period of growth. My thanks to Kirsten and Jeanne for all the times you helped me with rooms, beamers, faxes, etc., as well as the ever helpful people from the computer group, who maintain the most stable and visitor-friendly computing environment I have encountered so far.

My thesis research has been primarily funded by NWO, through the Spinoza grant of Professor Ewine van Dishoeck. In addition, I am grateful for the financial support from the Leidsche Kerkhoven Bosscha Fonds, Leids Sterrewacht Fonds, the c2d pro- gram and the European PLANET network, for conferences, work visits and observing trips.

The wealth of observations which form the basis of this thesis are all thanks to the many national and international collaborations which Leiden Observatory and parti- cularly our Astrochemistry group are involved in. Within the Dutch astronomical com- munity, I have enjoyed participating in the ISM/CSM meetings and the Dutch VISIR GTO team. An essential part of this thesis are the observations I have carried out at the ESO telescopes in Chile, and I’m grateful to their staff for making those visits both sci- entifically fruitful and enjoyable. I consider myself fortunate to have been involved in the Spitzer Legacy program “From Molecular Cores to Planet Forming Disks”, which brought me, straight from the start of my thesis research, into contact with a large in- ternational group of talented researchers and which has offered many opportunities to travel the world for team meetings, conferences and work visits as well as collabo- rations for the future. The program has led to a wealth of interesting observations, of which only a small fraction is covered in this thesis.

On both a scientific and social level, I have really enjoyed my time with all the people from the Astrochemistry group and recently also the Disk Evolution group. I’m glad chance brought me into the North End club on the third day I started here. We never quite managed to do one of their whiskey tasting nights but I believe our New Year’s party made up for it. A big thank you to all the people who have contributed to and shared in our little coffee club. At last count we have pinned up forty-two different coffee labels!

PAHs in Disks around Young Solar-type Stars 124

To my office mates: Jean-Charles, our discussions were always educating and en- joyable and helped me out a lot when I just started. Saskia, I have great admiration for the light-hearted manner in which you managed to complete your thesis, despite the difficult circumstances. Dave, I owe it to you for upholding our fine coffee tradition, especially after Fredrik, Jes, Jean-Charles and Klaus left.

Tot slot een woord aan mijn ouders en familie. Jullie onmisbare steun, advies en interesse hebben mij altijd geholpen om mijzelf verder te ontwikkelen.

Kerstin, jouw onvoorwaardelijke liefde, geduld en zorg hebben dit alles mogelijk gemaakt. Ik heb geluk dat ik mijn jaren in Leiden met jou mocht delen en ik kijk uit naar ons nieuwe avontuur.
