Originally from Palembang in Southern Sumatra, Dedy Sufriadi is the second of six siblings and began painting seriously at the age of 15 while still in Senior High School for the Arts (SMSR). From there, he went on to study at the prestigious Indonesian Institute of the Arts (Institut Seni Indonesia) in Yogyakarta, better known by its Indonesian acronym ISI, where he majored in painting. In 2013, he obtained his Masters degree from the same institution.
Dedy is an avid reader, seriously consuming books ever since he began his tertiary education in 1995. One specific area he is particularly well read in is existential philosophy, a subject that has strongly informed his artistic endeavor. Among the books he has read over the years include philosophical heavyweights such as Friedrich Nietzsche, Jean Paul Sartre, Søren Kierkegaard, Martin Heidegger, and Albert Camus, among others.

Because of his love for reading, it should come as no surprise that text has become a very important element in his art. Dedy also notes the ubiquitous nature of text, as a means to convey information, citing the often-overlooked fact that we are subjected to text, in its various forms and mediums of presentation, at almost every waking moment.

Earlier in his career, a time that Dedy describes as his Existentialist Period (1998 – 2004), text was used in his paintings in a manner that could be described as complementary to what was presented on the canvas. The text was more distinct, and one could visually track and verbalize what was presented quite easily, although portions may have been obscured.

He joined Global Artist Committee of Asian Art Association in 2020.
