Pujol was born in 1957 in Havana, Cuba and spent time in San Juan, Puerto Rico, and in Madrid and Barcelona, Spain, before moving to the United States in 1979.
He pursued graduate work in education at the Universidad Interamericana in San Juan, Puerto Rico, in art therapy at Pratt Institute in Brooklyn, and in communications and media theory at Hunter College in New York City.
Pujol first became known during the 1990s for a series of site-specific installation projects that dealt with whiteness, masculinity, collective and individual memory, loss and mourning.
His more recent performance work deals with subjects such as war, the environment, and consciousness, influenced by Zen Buddhism.
Two of his largest scale projects to date took place in Salt Lake City, Utah (Awaiting, 2009) and in Honolulu, Hawaii (Speaking in Silence, 2010).
