Outreach

Apart from being a research astronomer, I also enjoy being active in various outreach projects. Please see below for any upcoming activities, and a record of past activities as well as links to some of my popular science articles (including my — now archived — blog). I am also active on Twitter (although not only about astronomy). Follow me!

And I’d be happy to hear from you, if you have an outreach idea or would like to organise an outreach event.
