Pedro José Sebastião is an experimental physics professor with the Department of Physics of Instituto Superior Técnico, Universidade de Lisboa. Following the work for his Ph.D. thesis, in 1993, on molecular dynamics in liquid crystals with peculiar polymorphisms by proton nuclear magnetic resonance (NMR) relaxometry, he has investigated a large number of condensed matter systems using NMR. His aim has been to understand the interdependence between molecular organization and molecular dynamics in different systems, like liquid crystals, dendrimers, polymers, electrolytes, and other heterogeneous systems. He has been focused on the development of new, more efficient  Fast Field-Cycling NMR relaxometry equipment, in order to cover a broad range of NMR frequencies (from MHz to kHz), hence gaining information about molecular motions at different time and length scales.
