I am Severin Kacianka and you just found my personal website. It contains some old blog posts of mine and should probably at some point in time be updated with some more information about me.
In short, I am a PhD candidate at the Technical University of Munich (see my Bio) and work on accountability of computer systems and more specifically how to express this tricky concept in a formal way. As a solution, me and my collaborators suggest to use Structural Causal Model, a very recent mathematical framework to express and reason over causality. You can find my publications on google scholar.
