VP of Product
Jason joined Twitter in February 2007, and he is Twitter’s VP of Product. Prior to Twitter, Jason worked at Google where he was the product manager for Blogger for four years. Just a few days before starting work at Blogger, Google offered terms to acquire the company (but that’s probably a coincidence).
Jason graduated from Princeton University in 1999 with a degree in astrophysics. While there, he wrote a senior thesis with the punchy title "X-Ray Clusters of Galaxies, the Baryon Fraction and the Mass Density of the Universe." He is now unable to explain the contents of this document.
