{{< figure class="avatar" src="img/author.jpg" alt="avatar">}}
Researcher and software engineer based in Karlstad, Sweden. I earned my
[doctoral degree][] from [Karlstad University][]. My current workplace is
[Glasklar Teknik AB][], a sister company to [Mullvad VPN][]. I have a keen
interest for the overlap between research, development, and operations. Some of
the topics that I am most passionate about include transparency logs, anonymity
networks, applied cryptography, and Linux.

When I am not immersed in the world of technology, you will likely find me honing
my culinary skills, socializing with friends, going out on walks, hitting the
gym for weightlifting sessions, or showering my beloved cat with affection.
# Project involvement
I am a core member of the following projects:
- [Sigsum][]: a free and open source software project that makes a signer's
key-usage transparent. It can be used as a building block to secure the
supply chain and more.
- [System Transparency][]: an open source project that provides a security
architecture for bare metal servers. A system's entire boot chain becomes
protected and auditable.
- [Tor][]: a 501(c)(3) US nonprofit that advance human rights and defend online
privacy through free software and open networks.
