I'm a program-specific researcher (post doc) at ASHBi, KUIAS, Kyoto University in Seirin-Lee's lab.

My expertise is to apply math and computer science to real biology.

I studied mathematics at TU Kaiserslautern with stays at TU Delft and The University of Auckland, and obtained my PhD at University of Vienna in Sara Merino-Aceituno's group.

You can find a description of my current projects in the research section, talk and activities here and more info in my CV.

Software packages

I am currently making various tools for agent-based modelling available as Julia packages.

  • SpatialHashTables.jl: A Julia package for spatial hashing of particles (in 2D and 3D). This allows fast collision detection even is unbounded domains.
  • BoundedDegreeGraphs.jl: A Julia package for graphs with bounded degree, with focus on allocation free operations commonly used in agent-based modelling.

  1. EMT stands for epithelial-to-mesenchymal transitions, a process responsible for good things like neural crest formation and wound healing, but also bad thinks like cancer and fibrosis. β†©οΈŽ
