Ruffolo is a professor at Mahidol U. He obtained his PhD in 1991 at U Chicago. He developed a classic transport equation for solar energetic particles and precision modeling of their observed distribution in space. He created new theories of turbulent transport of cosmic rays, including an explanation of solar particle dropouts in terms of solar wind turbulence and topological trapping. He led the establishment of a neutron monitor in Thailand, which detects galactic cosmic rays at the world's highest geomagnetic cutoff energy. He has twice served as a rapporteur of the International Cosmic Ray Conference. He was awarded the Golden Eagle Award from the American Academy of Achievement and the 2017 Outstanding Scientist Award of Thailand.
