Public engagement
I find public outreach work exciting and fulfilling, and consider it an important part of an academic career. With David Reutter, I have developed a public engagement workshop, called Qubit.Zone, where participants can explore exciting quantum ideas—including superposition, entanglement and teleportation—using hand-held electronic qubit simulators. A list of all my group's public engagement activity is given below. If you would be interested in having a Qubit.Zone workshop as part of your event, get in touch!
[E10] August 2018. We gave a Qubit.Zone workshop at Brasenose College, Oxford to a group of students from under-privileged backgrounds with an interest in maths and science. (Fatimah Ahmadi and Jean-Simon Lemay.)
[E9] June 2018. We gave a Qubit.Zone workshop at Corpus Christi College, Oxford, to an audience of 25 students in year 12 from schools in the north of England. (Fatimah Ahmadi and Linde Wester.)
[E8] June 2018. We gave two public workshops at the Hay Festival under the title "Build Your Own Quantum Computer!", with about 20 participants per workshop. (David Reutter and Jamie Vicary.)
[E7] April 2018. We gave three Qubit.Zone workshops at the Department of Physics in Oxford, as part of the event Marie Curious — Girls Exploring Science. There were about 15 girls per workshop. (Fatimah Ahmadi and David Reutter.)
[E6] April 2018. We gave a Qubit.Zone workshop at the Department of Computer Science, University of Oxford, as part of "Target Oxbridge", an event to encourage applications from black and mixed-race students. (Benjamin Musto and Dominic Verdon.)
[E5] February 2018. We gave two Qubit.Zone workshops at University College in Oxford as part of a mathematical sciences study day for high-achieving Year 12 students, with about 20 students per workshop. (David Reutter and Dominic Verdon.)

[E1] June 2017. We gave two public workshops at the Cheltenham Science Festival with the title "Build Your Own Quantum Computer!", each with 20 participants. (David Reutter and Jamie Vicary.)
Other things
Here's some other things I'm doing at the moment.
I maintain two popular mailing lists, one for international quantum foundations announcements with over 950 subscribers, and another for quantum computing and quantum foundations events taking place in Oxford with around 100 subscribers. Please get in touch if you'd like to be added to either of these.
I am the lecturer for Categorical Quantum Mechanics (with Dan Marsden, and originally with Chris Heunen). These notes are being turned into a textbook with OUP, to be published soon.
I frequently supervise DPhil, MSc and undergraduate students on topics related to the mathematical foundations of quantum computing. If you'd like to work on a project with me, get in touch.
Biography
I did an undergraduate degree in Physics at Mansfield College, Oxford, followed by the Part III mathematics course at DAMTP and Trinity Hall, Cambridge. I then did a PhD in category theory and the foundations of quantum information with Chris Isham at Imperial College London, which was awarded in 2009. Since then I have been based in Oxford, becoming a Senior Research Fellow in 2013. In the period 2011-2014 I also held a Senior Research Fellow position at the Centre for Quantum Technologies in Singapore.
