I am currently a Short-Term Fellow at CRI Paris, 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). I obtained a PhD in mathematical physics from Humboldt University Berlin in 2012 for work at the Max Planck Institute for Gravitational Physics Golm and Humboldt University Berlin (2008-2011), where I have also conducted my Diploma thesis work (2007-2008) after studying physics and biophysics at HU Berlin.
