Hui Xu: Hui Xu is studying the formation of multilayer structures at wet interfaces from surfactant and polyelectrolyte/surfactant mixtures using neutron reflection and small angle scattering. She has a Masterís degree from Jiao Tong University (Shanghai). Just before coming to Oxford, she worked in the University of Bristol as a project student. This photo was taken at Yan Dang Mountain, a famous attraction in China. Hui hopes that the exploration of the structure of surfactants will be as interesting and enjoyable as mountain climbing.
