Fue un astrofísico de renombre internacional y su obra lo hace ser un orgullo para su país, Bolivia.Hasta 1968 Experimento sobre la “Cascada atmósférica” (BASJE Bolivian Air Shower] Joint Experimen) en Chacaltaya, Bolivia, para la búsqueda astronómica de rayos gamma de alta energía.Experimento EAS-TOP en el Laboratori Nazionali del Gran Sasso, Italia, hasta 2002, para el estudio de las características de la “Cascada atmosférica extensa” (EAS Extensive Air Shower) a 2000 m s. n. m. Estudio de “Neutrinos en el colapso de estrellas” con el Detector de Gran Volumen (LVD Large Volume Detector), LVD y On-line recognition of supernova neutrino bursts in the LVD detector del Laboratori Nazionali del Gran Sasso, Italia.18-22 de junio de 2007 Looking for the high energy component of GRBs at the Large Aperture GRB Observatory High Energy Cosmic Ray Interactions , First School Of Cosmic Rays And Astrophysics.a) “Limits on low energy neutrino fluxes with Mt.
