Why THEIA?

All great research starts with a story. Our group’s name THEIA lab is derived from the Greek goddess Theia, also referred as the Titan goddess of sight (thea), and the bright blue sky (aithre). Also, Theia’s brother is Hyperion, who is a god of the sun. Quite interestingly, our group’s research is focused on computer vision, solar and renewable energy etc. Credits to Murhaf and Fabrizio for this wonderful idea.
