Logician & philosopher @ruhr-uni-bochum.de, Post-Doc. I like proof theory, proof-theoretic semantics, feminist logic, bilateralism, and a lot more in logic and in life. (she/her)
Another paper of mine published open access now: "Problems and Consequences of Bilateral Notions of (Meta-)Derivability" in Erkenntnis! 🎉

🚨NEW PAPER ALERT🚨

And with perfect timing, Franci Mangraviti's 🚨OPEN ACCESS🚨 paper "Feminist logic, broadly speaking", has just been published in Synthese 206, article no. 82: link.springer.com/article/10.1... !
Feminist logic, broadly speaking - Synthese
I argue that the continued focus on the possibility question - whether feminist logic can exist as a respectable practice - has several harmful consequences. First, it invites the association of femin...

Paper publishing alert 😄
My dear colleague Hrafn Oddsson and I have written a paper in which we show "Proof-Theoretic Functional Completeness for the Connexive Logic C". It's now published with open access in Studia Logica:

Information Feminist Logic is a relatively new but upcoming area of study. Work in this field sheds light on sexist (and other) biases in the area of logic. This is a very broad conception but it capt...

A little article in @ruhr-uni-bochum.de magazine about our logic group and how our research on contradictory logics apparently would be devastating for Aristotle 😄

Eine Katastrophe für Aristoteles
Bochumer Forschende untersuchen logische Systeme, in denen Widersprüche beweisbar sind. Dem einflussreichen Philosophen Aristoteles hätte das gar nicht gefallen.

Coming home after a full week of workshops and traveling:first I talked about logical bilateralism at a Symposium on Proof-Theoretic Semantics in London and then about Feminist Logic in Frankfurt at a workshop with Graham Priest.A long week but full of interesting discussions with great logicians😊

Very important remarks and observations on logic and gender representation, thanks @johannamath.bsky.social !

(It's like this at most logic conferences, not only in maths...)

I was at #JMM2025 this past week, and I went to as many ASL invited addresses/contributed talks as I could. Some things to think about on #WorldLogicDay:

Coming back to Bluesky after a break, let me advertise a recent paper of mine I'm quite proud of! In this paper, I propose a way to read topics off of a space of propositions forming an algebra, and tie this in to a topical reading of relevance in logic:

Topics in Relevant Logic: A Semantic Perspective - Erkenntnis
This paper concerns the interface between relevant logics and recent developments in semantics for hyperintensional operators. In the latter area, the notion of topicality or aboutness has begun to pl...

I recently heard that there's this unspoken law (which I apparently ignored) NOT to work on feminist issues BEFORE you have a permanent job... I started working on feminist logic, kind of naively expecting *some* backlash for sure but not nearly as much as I've encountered so far, (1/2)

Happy to report History and Philosophy of Logic published a translation that I did of an early logic article by Franz von Kutschera alongside with a short paper in which I contextualize this work 🥳
