Role at ANSTO


Dr Andrew Nelson an instrument scientist for the PLATYPUS neutron reflectometer. His main interests lie in the soft condensed matter area, specifically the interactions of polymers and surfactants with interfaces/colloidal systems - as studied by Neutron Reflectometry and Small-Angle Neutron Scattering.


Qualifications and achievements


  • He was responsible for building a successful user program on the HIFAR Neutron Reflectometer from 2003, before transferring focus to  PLATYPUS
  • Andrew Nelson received a MSci and his Ph.D. in soft condensed matter from the University of Bristol.
