K.L. Ivanov (International Tomography Center, Novosibirsk, Russia) was actively involved in teaching at the Novosibirsk State University, ITC Novosibirsk, and at various schools for young researchers, and was a specialist in NMR theory and NMR methods development, notably, spin hyperpolarization methods.P.K. Madhu (Tata Institute of Fundamental Research, Hyderabad, India) has contributed to NMR relaxation theory, methods development in solid-state NMR and biophysical applications of NMR. He currently has interests in zero-field NMR and application of NMR in perovskites and battery materials.G. Rajalakshmi (Tata Institute of Fundamental Research, Hyderabad, India) is an experimental physicist developing zero to ultra-low field NMR techniques for solid-state experiments. She also works on nonlinear optical-atomic magnetometry methods for detecting dc to rf magnetic fields.
