About me: I am the head of quantum algorithms at Amazon Web Services  and a professor of theoretical physics at Caltech division of Physics, Mathematics and Astronomy.

Previously I was visiting faculty at Google’s Quantum AI Lab (2018-2019), a researcher at Microsoft (2015-2016) and a reader in computer science at University College London (2013-2016). Before that I was a senior researcher at ETH (2012), after being an assistant professor of physics at UFMG (2011-2012). I hold a PhD from Imperial College London  (2008), and was a postdoctoral fellow at Imperial College London (2008-2010) and UFMG (2010-2011).

Research:  My research is on quantum information science. I explore
the interplay of physics, computer science and math to study the role of
quantum mechanics in computation and information processing.
