Continuing our recent servings of fresh blogging meat, I am delighted to announce the addition of another new member of the Cosmic Variance team. Daniel Holz is a Richard Feynman Fellow in the theoretical astrophysics and particle physics groups at Los Alamos National Laboratory, working on the interplay between general relativity, astrophysics, and cosmology. Dan is a particular expert on gravitational lensing and gravitational waves, but his interests are wonderfully broad and I know he's going to bring a great new perspective here. As a good friend of some of us already, he's been mentioned in at least one of our previous posts. In addition to his scientific expertise, Dan adds important non-Californian balance to the blog, although his history at Santa Barbara, and his obsession with surfing worry me a little. Despite the impression one gets from visiting Dan's home page, I can assure you that his face does not, in real life, look like an apple, as his

Cosmic Variance page will no doubt soon show. Welcome Dan!
