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!

    Thanks Amara! Cavafy is one of my favorites.

    I met Daniel Holz while at Los Alamos. He’s a great guy. Congratulations Daniel.

    Hi Daniel,

    Welcome to the party!! Great to see the recent expansion in this region of cyberspace.

    surfers understand gravities waves better, particularly when they come in big sets with long wave periods

    Daniel??? That guy’s a total bum.

    (PS: Since the humor probably doesn’t come through, he and I are probably coauthors on 25% of each other’s publication lists, and just spent an hour chatting on the phone. Which is all to say that I can authoritatively label him a bum.)

    Welcome Daniel! Nice first post, complete with capitals and punctuation and everything.

    From down the road at the Santa Fe Institute, welcome! (Also, glad to see a fellow snowboarder in the mix!)

    glad to see a fellow snowboarder in the mix!

    Two, actually…

    And of course, welcome Dan!

    Thanks for all the welcomes! And ignore that Scott guy, he’s a total crackpot. Except for the papers we co-author, of course.
