Seiko Ohira-Kawamura is the contact person for the cold-neutron disk-chopper spectrometer, AMATERAS, at J-PARC MLF. She is involved in the development, upgrades, and user support for the instrument. Her original research focuses on magnetism in molecule-based organic magnets, quantum spin systems, and organic conductors, using muon spin rotation/relaxation/resonance and neutron scattering techniques. Additionally, she is also a member of the Sample Environment team at MLF and contributed to the development of cryogenic environments during the first ten years.
