Hey there. I was born in Ireland in the 70s (how auspicious, I am sorry I don’t have any colour photographs of Ford Cortinas here). After a lot of travelling, I’m now living in Paris since 2003.

I work on all the interesting things that we currently know the least about (dark matter, dark energy).

Clearly, I am not sure who my target audience is, as you’ll find here a somewhat unorganised mix of posts about astronomy, philosophy, history, and anything else which happened to interest me at the time.

Well, that’s it. I am pretty easy to find out there, but here is a contact form:
