This is the personal blog of Ken Caldeira.
My main professional web site, and also the web site for the collaborative group in which I am enmeshed, is climate-energy.org.
I work for Breakthrough Energy.
I lead a research group at Carnegie Institution for Science on the Stanford University campus.
I have a LinkedIn page and a Twitter account.
Reuters did a biographical sketch of me a few years ago that is a good general overview (thanks, Maurice Tamman!).
