PhD student at Karlstad University.  Software engineer at Mullvad VPN.
I am passionate about transparency logs, anonymity networks, and Linux.  I have
a keen interest for the overlap between research, engineering, and operations.
Off-work I cook, walk, socialize, lift weights, and spoil my cat.

# 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.
