Between 1998 and 2000 he took occasionally analysis and composition lessons with Rodolfo Acosta R. At the end of 1998, without having finished his studies, and after having failed in his effort of adapting to the academy, he decided to interrupt his studies and dedicate himself to composition as a full-time activity. In 2001, he decided to undertake a trip to Switzerland with the purpose of styding once again. Basel was the place he chose for this. He studied composition with Detlev Müller-Siemens and Erik Oña, and other subjects with Dorothé Schubarth, Roland Moser, Hanspeter Aeschlimann, Markus Jans, Hans Saner and Jakob Ullmann, among others. He has taken part of several seminars, courses and workshops in Colombia, Spain, Hungary, Germany and Switzerland, as well as composition masterclasses with Coriun Aharonian, Graciela Paraskevaidis, Beat Furrer, Michael Jarrell, Jonathan Harvey, Marco Stroppa, Klaus Huber, Mark Andre, Brice Pauset and Helmut Lachenmann, among many others. In 2008 he assisted the german composer Jakob Ullmann (*1958) in the realization of the electronic part of his piece PRAHA: celetná-karlova-maiselova, commissioned by the Deutschlandfunkf, and premiered at the Forum für Neue Musik 2008 in Cologne, Germany.
