Born in Beirut in 1951, El Rawas studied painting at the Institute of Fine Art of the Lebanese University, and graduated in 1975 with honors receiving   the Lebanese University scholarship to study abroad. The year of his graduation marked the beginning of the civil war in Lebanon, leading the artist to stop painting and to leave his country to Morocco where he stayed for two years in Rabat, teaching art and resuming painting. He returned to Beirut in 1979 to hold his first solo show, before joining the Slade School of Fine Art in London in the same year. Upon his return to Beirut in 1981 with a Masters Degree in printmaking, he started his academic career at the Lebanese University and the American University of Beirut, that lasted for 27 years. 

Since 1979 El Rawas has held 12 individual exhibitions in Beirut, London and Dubai and has participated in more than 40 international art biennials and exhibitions in the UK, USA, Norway, Tunisia, Brazil, Japan, Kuwait, France, Netherlands, Egypt, UAE, Poland and China. In these international shows he won five prizes and honorable mentions including, in 2007, the award of the Alexandria Biennale for Mediterranean Countries, for his first installation and video art piece.  His work is found in many museums and public collections in Lebanon, Tunisia, Iraq, Jordan, UAE, Norway and the UK.
