Miriam also works on properties and applications of high-level graphical languages for quantum computation which arise from category theory. Previously, Miriam was a postdoc with Ashley Montanaro at the School of Mathematics, University of Bristol. They completed their doctorate in the Quantum Group at the Department of Computer Science, University of Oxford, in 2016, supervised by Bob Coecke and Samson Abramsky. Miriam holds an MMath and a BA in Physics from the University of Cambridge.

Ana Belen-Sainz, University of Oxford and Perimeter Institute for Theoretical Physics

I am a postdoctoral fellow in the Quantum Foundations group at Perimeter Institute for Theoretical Physics in Waterloo, Canada. My research mainly focuses on the characterisation of quantum phenomena, with special interest on the possibilities and limitations of quantum technologies. I am originally from Argentina, and did my undergraduate studies at Universidad Nacional de Córdoba. My first research activities were supervised by Prof. Ricardo Zamar, at the NRM research group, on theoretical aspects of the dynamics of spins in liquid crystals. Afterwards, I moved to Barcelona to learn and work on Bell nonlocality, among other nonclassical phenomena. There I did both my Master and PhD theses under the supervision of Dr. Antonio Acín at ICFO-The Institute of Photonic Sciences. Before my current appointment, I spent a couple of years as a postdoc in the group of Prof. Popescu at the University of Bristol. In my personal time I enjoy doing pottery, playing cello, and volunteering for charities.
