I’m a cryptographer, with a focus on practical implementations, cryptanalysis, and protocols related to post-quantum cryptography. You can find a link to my publications on Google Scholar.
I am currently a Staff Research Scientist in the Quantum Security Group at SandboxAQ. At SandboxAQ we have a lot of great opportunities for Residencies, which can be for anyone from postgraduates to postdocs, for 3-12 months. Please feel free to get in contact to informally enquire, I would be interested in topics (in PQC or others) ranging from FPGA or microcontroller designs, side-channel analysis and countermeasures, protocol design, crypto-agility, and developing our open-source tools at SandboxAQ. We also have other researchers, such as Martin Albrecht, who have other topics in mind.
I’ve had the pleasure of supervising Paula Alonso Blanco, Sanjay Deshpande, Tarun Yadav, as well as many others in a more informal setting.
For 2.5 years, I was employed as a Cryptography Engineer at PQShield Ltd, a small spin-out company from the University of Oxford. Previously, I was a post-doc at the University of Bristol in the SCA / Crypto group and at CSIT where I also did a research fellowship and my PhD. Other previous research positions and education history can be found in my CV.
The focus of my research is mainly based around (but not limited to) post-quantum cryptography. My research has somewhat been focused on implementations (optimisations for hardware and software designs), physical implementation attacks (side-channel and fault attacks) and countermeasures. Also I have been researching protocols (such as KEMs, signatures, and beyond) and algorithmic optimisations.
