Born in Buenos Aires, he studied at the Fine Arts School and later moved to Madrid. In 2008 he began collaborating with the publication Madriz, developing a series of projects that illustrated the covers and interiors of 15 numbers. In these series, with Madrid as a common denominator, Maselli develops his particular and idealized vision of the city. With these photporaphies he edited a book too.

Between 2011 and 2013 he develop his project Hierophanies, which is an intellectual and empirical approach to the work of philosopher Mircea Eliade, who coined this term to refer to an awareness on the nature of the existence of the sacred.

Maselli is currently developing a project in the mountains, which attempts to approach the concept of the sublime and the possibility of translating it into a contemporary artistic language.

His work has won numerous awards and has been exhibited in galleries and international art fairs: SPD – The Society of Publication Designers (New York), W-CA Open Contemporary Landscape Photography (UK), Young Arts Award from Complutense University (Spain), Copenhagen Photo Festival (Denmark), NodArt 2014 (Germany), 13ª Mostra Internacional Gas Natural Fenosa (Spain), among others.
