About me

  • I work days at Stone Three and nights at the vxlabs.
  • My specialities include medical visualization (taught it, researched it, applied it, co-authored The Book), data visualization (ditto, minus the book), (medical) image processing and analysis, and software engineering.
  • See this probably outdated list of the software I’ve worked on, or rather go to my github profile to see what I’m working on right now.
  • Connect with me on LinkedIn.
  • Since recently, you can find me on Blueskye as @charlbotha.com. I really like that they’ve made it super easy to use your domain as your handle!
    • Sometimes I also lurk on Threads. I like that it’s ActivityPub, but I haven’t really been able to find connection there.
    • I do have an account on the network previously known as twitter. This is great for ML news, not so much for the rest.
    • My favourite used to be the Mastodon server emacs.ch, but unfortunately it is shutting down end of 2024. Also, it turns out that I really like the discovery aspects offered by decent algorithms, something which Mastodon does not offer. Nonetheless, I have created a new account on mastodon.social in case you prefer to connect there.
  • Send work-related email to cpbotha@vxlabs.com or personal email to info@charlbotha.com.
