Thermodynamics & stat physics

  • Nano particles: We try to better understand the effective molecular forces in systems with 1-10k interaction sites performing MD-simulations and data mining.
    • Bauer G, Lange A, Gribova N, Holm C, Gross J. Effective potentials between gold nano crystals - functional dependence on the temperature. To appear in: Molecular Simulation [arXiv:1403.5950]
  • Density functional theory: We model basic molecular interactions in a calculus of variations setting, determine properties of gas-liquid interfaces, and compute characteristic physical values such as the surface tension.

Bio math

  • Networks & diversity / evolution: We explore strategies of pathogens and their dependence on the host-contact network.
    • Lange A, Ferguson NM. Antigenic diversity, transmission mechanisms, and the evolution of pathogens. PLoS Comput Biol 5 (10): e1000536 
  • Infectious diseases / ecology: We investigate disease transmission based on epidemiological data such as incidence or disease-related mortality.
