- I am serving as PC chair for the 7th International Conference on Quantum Cryptography, QCRYPT'17. Submit your best quantum crypto papers! (Deadline: April 26th, 2017.)
- Watch an introductory talk presenting some of my research in quantum cryptography at the Caltech Computes conference in November 2016.
- I organize the CMS Theory seminar.
- I help organize TCS+, an online seminar series in theoretical computer science, accessible to the widest possible audience, and ensuring a carbon-free dissemination of ideas across the globe. See our website for more information.
My research is centered around problems at the interface of theoretical computer science, quantum information and cryptography. I like to use complexity theory as a tool to study problems in quantum computing, and quantum mechanical phenomena as a way to gain a new perspective on classical concepts from theoretical computer science.
