About Davide Castelvecchi

I am a staff reporter at Nature in London and a contributing editor (formerly a staff senior editor) for Scientific American magazine. I have also been a reporter at Science News magazine and I have written for Physics World, New Scientist, Sky & Telescope, National Geographic News, and Physical Review Focus.

My blog, Degrees of Freedom, covered math, physics, and combinations thereof on the Scientific American Blog Network.

Before going back to school to study science writing at the University of California at Santa Cruz, I was a mathematician. My research field was topology and geometry (specifically, if this means anything to you, noncommutative measure theory of foliated dynamical systems). I have a Ph.D. from Stanford University, did a postdoc at the University of Paris-Sud at Orsay, and taught at the University of California at Santa Barbara and at the University of Rome II.
