Research Focus

Resource conservation, recycle and reuse: via process intensification and reactor engineering

  • Chemicals & materials: develop and apply novel process intensification strategies & devices to improve performance (selectivity, spatial foot print, environmental foot print, safety, etc)
  • Energy: intensify waste biomass to energy & value added chemicals processes
  • Water: develop novel distributed water treatment, recycle and reuse technologies

Tailoring functional products & materials: via new fluidic devices, computational models and process intensification

  • Pharmaceuticals: continuous processes for tailored crystals & nano-particles
  • Foods & cosmetics: crystals, emulsions, nano-dispersions, structured liquids

These goals are being pursued by mastering multiphase flows with phase change, by developing multi-scale computational models and by developing novel fluidic device platforms to realize new insights, innovations & intensification solutions. This new knowledge is expected to expand, enrich and strengthen the chemical engineering domain and impact on society
