Free software hacker, systems and security researcher.
I am currently a Postdoctoral Research Fellow at the University of British Columbia with Margo Seltzer.
Earlier, I did my PhD with Pierre Olivier at the University of Manchester. My PhD thesis received the 2025 EuroSys Roger Needham PhD Award. I was a Microsoft 2022 PhD Research Fellow. I visited/interned at SCI Semiconductor, MSR Cambridge (Confidential Computing), and NEC Labs Europe between 2020 and 2024.
Free Software
I have been active in various free software communities for over a decade. I contributed to many free-software projects, including the Linux kernel, but most notably:
-
The Debian project, where I have been a Debian Developer with uploading rights for about 8 years until 2023, when I retired. Most of my Debian work was related to packaging and security. I contributed extensively to the Debian LTS team, and more occasionally to the security team.
-
The Unikraft unikernel framework, where I have been a core maintainer since 2019, now focused on security aspects.
-
The CHERIoT real-time operating system, where I have been a contributor since 2024, focused on the network stack.
-
The Jami communication platform (GNU project, formerly Ring), where I was a core developer between 2018 and 2019.
Nowadays, my free software involvement is centered around CHERIoT, Unikraft, and my own research projects.
