I am a CNRS researcher in theoretical computer science at IRIF, Université de Paris. Previously, I have been a Short-Term Fellow at CRI Paris in spring and summer of 2020, working on the development of tracelet-analysis algorithms for the biochemistry platform Kappa and for the organo-chemistry platform MØD. I previously held a Marie Skłodowska-Curie Individual Fellowship (2017-2019), working in the field of theoretical computer science at IRIF, Université Paris Diderot. The aim of my project with Jean Krivine (IRIF) consisted in developing extensions of my rule-algebraic framework to restricted variants of rewriting and to the biochemical reaction language Kappa. I am also frequently to be found at the LPTMC of the UPMC/Sorbonne/Paris 06, working with Gérard H.E. Duchamp (Paris 13) and Karol A. Penson (Paris 6) on topics in combinatorics. My previous positions include a Postdoc position with Vincent Danos at ENS Paris and at University of Edinburgh (2014-2017) and a Postdoc position in mathematical physics with Anatoly Konechny at Heriot-Watt University in Edinburgh (2011-2014).

Together with Andrea Corradini, Reiko Heckel and Jean Krivine, I am organizing the GReTA - Graph Transformation Theory and Applications online seminar series - see www.irif.fr/~greta for more information and seminar announcements.

News

New preprint: “Fundamentals of Compositional Rewriting Theory” (joint work with R. Harmer and J. Krivine),

I have been invited to give a talk on June 9, 2022 at the Topos Institute Colloquium, a very active and inspiring seminar series on applied category theory (cf. the TIC YouTube channel).

I am a co-chair (joint with Daniel Strüber) of the 15th International Conference on Graph Transformation (ICGT 2022).

Selected Talks & Activities

Software

Based upon joint work with Reiko Heckel and Maryam Ghaffari Saadat (University of Leicester), I am developing the ReSMT Python package, which aims to implement rewriting-theoretic concepts via utilizing the Microsoft Z3 theorem prover as the computational core. At present (v. 0.0.3), the package covers typed directed multigraphs (TDGs) with structural constraints as its base datatype, with some of the key operations implemented including the search for partial overlaps of TDGs modulo structural constraints formulated via forbidden pattern non-embedding assertions.
