RESEARCH INTERESTS(Google Scholarresearch ID at ISI Web of Science, ORCID):  

  • Structure and dynamics of colloidal systems, such as nucleation/clusterization in colloidal and biological molecular assembly systems, ion/counterion association in polyelectrolyte solution, and colloidal interactions.
  • Interaction of small molecules on the surface or porous media, such as hydrogen storage, green-house gas capture, molecular recognition based on surface selection, molecular sieving, small molecule dynamics on functionalized surface.
  • Neutron and X-ray scattering techniques

Selected Awards:

  • Silver Medal of Department of Commerce of USA for individual due to the contribution to identify the root cause of a major obstacle preventing the realization of the full potential of promising new monoclonal antibody therapies, (2019)
  • Science Prize of Neutron Scattering Society of America for “the discovery of dynamic cluster ordering in complex colloidal and protein systems using neutron scattering” (2016).
  • Distinguished referee of The European Physical Journal (2015).
