I lead the Mathematical Quantum Information research group at RIKEN's Center for Quantum Computing in Japan.

My interests lie in the mathematical characterisation of quantum resources, the convex optimisation problems involved in their quantification, and their applications in quantum information theory. I like to generalise things.

Previously, I was a JSPS Postdoctoral Fellow at the University of Tokyo, and before that a Presidential Postdoctoral Fellow at Nanyang Technological University in Singapore. I obtained my PhD degree in mathematics from the University of Nottingham under the supervision of Gerardo Adesso.

Open positions: I am hiring multiple postdoctoral researchers.
