The Coffee Gear I Use

About me

I’m a researcher in astrophysics at the Montreal Rio Tinto Alcan Planetarium, and an adjunct professor at Université de Montréal – I write about my science projects here. I love to think about coffee brewing and use the tools of science to learn how to brew better coffee. Hopefully, you will find on my blog some things that are also useful to you.
