Public outreach

Part of my job is disseminating the science we do here at the Cosmic Dawn Center. Get in touch if you want to hear about astronomy — I happily give talks and interviews, as well as take part in more untraditional events.

Press releases and news stories

I regularly write small articles in laymen's terms about our research at the Cosmic Dawn Center.

Popular science articles

In addition to the published articles above I've created a small encyclopedia for non-astronomers with short introductions for laymen to some of the stuff that I spend my time on.

I also tweet regularly about astronomy:

Public talks

I regularly give talks on various astronomy-related topics to high school students, amateur astronomy associations, companies, and the general public. Even in prisons!

Some topics of the talks I give are:

  • James Webb — the new space telescope
  • Galaxies — the building blocks of the Universe
  • Cosmology — then and now
  • Lyman α — a window to the distant Universe
  • The dark Universe (on dark matter, dark energy, and black holes)
  • Stars — birth, life, and death
  • Spectroscopy and astronomy
  • My research
  • Science communication
Contact me if you'd like me to come give a talk. It'll be fun!
