Cathy talks about clusters of galaxies at the meeting "Cosmology for All" in Lund (Feb. 2013). Picture by Robert Cumming.

I work on galaxies and galaxy clusters. I enjoy looking at the night sky with my dog in the evenings and being around observatories. I'm fortunate to work in beautiful Råö, observatorievägen, and to go to amazing places like the Atacama desert in Chile to search for distant galaxies and galaxy clusters with the partly Swedish APEX radio telescope, at 5200 meters above sea level. Although I can't tear myself away from observations, I also really love theoretical work and analytical and numerical modeling. I wish the day had more hours to do more of all those things!
