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.

My PhD project is about developing geometric and topological tools to help materials scientists describe and quantify entanglement in crystalline (3‑periodic) materials. Shown below is a 3D model of a 3‑periodic entanglement of filaments, generated with 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
  • Geometric and topological computational modelling, visualisation and analysis
  • Knot theory, entanglements and weavings
  • Interdisciplinary collaboration with materials science

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: \(\LaTeX\), Python, HTML, CSS, PHP, SQL.
  • Software & tools: Houdini (procedural generation & 3D animation).
