Acoustics and Vibrations
J.F. Hernández-Sánchez
Member of the academic staff
Born in Mexico City in 1982, he studied Mechanical Engineering at the Faculty of Engineering and earned a master’s degree in Materials Science and Engineering from the National Autonomous University of Mexico (UNAM), under the supervision of Roberto Zenit. He completed his PhD in the Fluid Physics group at the University of Twente in the Netherlands, under the supervision of Jacco Snoeijer. There, he specialized in experimental techniques used in fluid physics, primarily in capillary phenomena. He was a postdoctoral fellow at King Abdullah University of Science & Technology (KAUST) with Sigurdur T. Thoroddsen. There, he learned about ultra-high-speed flows and furthered the development of experimental and visualization techniques. He is currently an Associate Researcher ‘C’ in the Physical Acoustics and Fluid Dynamics Group at the Institute of Applied Sciences and Technology (ICAT) of UNAM. He has published articles on capillary phenomena, experimental techniques and ultra-high speed jet boiling, as well as aeroacoustic phenomena in synthetic jet actuators.
