Recent research spotlight: 

Quanta Magazine: The Quest to Quantify Quantumness

Researchers aim to analyse pangenomes using quantum computing

A quantum leap: mapping DNA diversity with quantum computing

Together with Tom Gur I am co-organizing Cambridge-Warwick Quantum Computing Colloquium 

I'm leading the following projects:

• Wellcome Leap "Human and Pathogen Quantum Pangenomics" , 2023-2026
• EPSRC Robust and Reliable Quantum Computing Grant "Structure and symmetry in quantum verification", 2023-2025. A short video of the kick-off event is available here.
• (jointly with Bipasha Chakraborty) Quantum Algorithms for Quantum Field Theory project, 2022-2025
