In 1972, Kokkin made her debut at the National Annual Autumn Exhibition while still a student at the Art Academy. In 1987, she moved to the US. Her break-through here came with the sculpture Flight, which initiated a series of themes with ballet dancers in which the artist expresses feelings through movement. Originality and strength of expression mark her works which are executed with attention to anatomy and details, and convey a sensual, yet energetic quality. The search for truth led her to the naturalistic language, and her fantasy led her to themes from the antique and mythological world. Kokkin has created a number of monuments, both public and private commissions. Her works span from the tradition of romantic expressionism to naturalism. She has sculpted themes from the marine world and has a career as a portrait artist. Kokkin’s artwork is placed all over the world, with the majority of pieces in the US and Norway.
