Me at ParanalI'm Roger Wesson, an astronomer working at University College London, where I investigate the dust associated with core-collapse supernovae and their progenitors, as part of the sndust group. Previously I spent four years in Chile, where I was a Fellow at the European Southern Observatory and spent 80 nights a year supporting operations at the Very Large Telescope, including nighttime support on UT3 (Melipal). Before that I was an undergraduate, postgraduate and postdoc at UCL. These pages contain information about my research.

I do a lot of astrophotography when I find myself in places with dark skies, and I am an ESO photo ambassador. More details on my photography page.

By a depressingly significant margin, the most popular part of of my website is still CMBR, a game I made in 2014 based on the wildly popular (at the time) 2048. I also made an absurd joke sequel, CMBR2, which is the second most popular part of my website.
