I'm a physics professor at Duke University. I study particle physics and cosmology. I'm a long time member of the Super-Kamiokande neutrino experiment in Japan and now focus on trying to understand the nature of Dark Energy with the @VRubinObsRubin Observatory.

I am also a member of the Rubin Observatory commissioning team. I took this photo working in Chile. It shows how far along the observatory already is. Look at the cars to get a sense of scale!

The Vera C. Rubin Observatory is shown in later afternoon light. The dome is open and although it is still a construction area (you can see cranes in the image) you can see that the outside of the observatory is near completion. The shiny aluminum coating on the dome is almost complete in the picture. I captured this image in November of 2022.
