About me: I am a professor of theoretical physics at Caltech division of Physics, Mathematics and Astronomy and a member of the Institute for Quantum Information and Matter

Previously I was 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.

I've been particularly interested in the following topics:

- Quantum information theory and entanglement theory
- Quantum hamiltonian complexity and quantum many-body physics
- Quantum complexity theory and quantum algorithms
- Connections of quantum computation and information to
   computational complexity, statistical mechanics, thermodynamics,
   optimization, Markov chains and resource theories
