  • 2017 - present: Lecturer in Applied Mathematics, Loughborough University, Loughborough, UK
  • 2014–2017: VISTA Postdoctoral Research Fellow of The Norwegian Academy of Science and Letters, University of Bergen, Bergen, Norway;
  • 2012– 2014: Postdoctoral Research Fellow of the Hungarian Academy of Sciences, Wigner Research Centre for Physics, Budapest, Hungary;
  • 2012: Ph.D. in Physics, Budapest University of Technology and Economics, Budapest, Hungary;

My main research field is theoretical and computational materials science, including:

  • Mean-field treatment of equilibrium crystal-liquid interfaces and the dynamics of complex solidification morphologies;
  • Analytic description of amorphous solids in the framework of classical density functional theories.
  • The fundamental understanding of the glass formation and the amorphous precursor-mediated crystal nucleation;
  • Developing a numerically efficient continuum theory describing pattern formation phenomena in multicomponent (complex) liquids;
  • Re-classification and extension of traditional hydrodynamic models: alternative interpretation of compressible and incompressible fluid flows, derivation of unified dynamic equations.
  • Finding the bridge between classical field theories and discrete microscopic models;
  • Implementing numerical algorithms for solving PDEs on massively parallel HPC devices (GPU programming).
