I am currently a PhD student in Applied Geometry and Topology at the University of Potsdam in Germany. My research is conducted under the supervision of Prof. Dr. Myfanwy Evans and Dr. Sonia Mahmoudi.
I completed both my Bachelor's and Magisterium degrees at the University of Strasbourg, followed by a Master's degree at the University of Rennes 1 in France. While Potsdam serves as my primary research base, I also spent a research period at the Advanced Institute for Materials Research (AIMR) at Tohoku University in Japan.

I develop geometric and topological tools to help materials scientists describe and quantify entanglement in 3-periodic structures. Such structures can represent a variety of biological, molecular, and chemical systems, including coordination polymers, metal-organic frameworks, covalent organic frameworks, liquid crystals, and DNA origami crystals. Shown below is a 3D model of a 3-periodic entanglement of filaments, created using Houdini. Alongside my research, I also tutor junior scientists in the use of various software programmes (such as Houdini) to model and explore biophysical systems.

Areas of interest and expertise:
  • Topology, geometry, algebra
  • Computational geometry, visualisation, and 3D animation
  • Knot theory, entanglements, and weavings
  • Interdisciplinary work across materials science, biology, chemistry, and physics

Besides my PhD work, I often attend or organise conferences, workshops, and courses.

Skills:
  • Languages: Malagasy (mother tongue), French (fluent), English (excellent command), German (basic communication skills).
  • Programming & computational skills: Python, \(\LaTeX\), HTML, PHP, CSS, SQL.
  • Software & tools: Houdini (procedural generation & 3D animation).
