One of the worst reference letter submitting experiences is with the International Max Planck Research School on Astrophysics. They ask you absurd questions outside of just uploading your letter, such as asking for arbitrary rankings of the student. There is no clarity how such information is used.

What a fun meeting #skao2025! I can not wait to see all the amazing science that will come from the SKAO. It was also great to catch up with so many fantastic scientists - including all these Dutch-affiliated (past, present and/or future) astronomers!

Ik ben Nederlander geworden / I have become Dutch
Yesterday, I attended my naturalisation ceremony to become Dutch! It is pretty wild to think that 8 years ago this Australian arrived in the Netherlands for a quick 3 year postdoc, with every intention of moving after that.

A new university beginning! I have now started as an Associate Professor at @api.uva.nl. I will be four days a week at @astronnl.bsky.social, and one day a week at API.
I look forward to continuing the tradition of uniting the strengths of these two institutes!
