Helen Walker is a staff scientist at the ISIS Neutron and Muon Source in the UK,  specializing in exploring the collective dynamics of functional materials. She holds an undergraduate degree in natural sciences from the University of Cambridge and a Ph.D. in experimental condensed-matter physics from University College London. Prior to becoming a neutron scientist, she worked at the European Synchrotron Radiation Facility in France and at PETRA III at DESY, Germany. Her research interests include magnetism in metal organic frameworks and structure-dynamics-property relations in barocalorics. She won the ESRF Young Scientist of the Year Award in 2011 and is currently one of the Foundation Future Leaders at the Foundation for Science and Technology in the UK.


Topological Magnetism Turns Elementary

Neutron scattering experiments provide the evidence of massless spin waves called Dirac magnons in a single-element magnetic crystal, offering a new window into topological magnetism. Read More »
