During my Ph.D. at the University of Campinas under the supervision of Dr. Erick de Moraes Franklin, I worked with solid-liquid fluidized beds in narrow tubes. This specific case was an exciting and rich problem because of the confinement effects which create quasi-1D waves within the granular bed. Our studies were helpful to connect various branches of engineering sciences and soft matter physics; from understanding the mechanisms that lead to the formation of the quasi-1D waves to connecting their behavior with the formation of glass and jamming in granular materials.
