Theadora presently alternates between living in London and Hong Kong. She has a degree in theology and law, and worked a while as a barrister in London and in Beijing. It was while working in Beijing and learning Mandarin that she started to draw and paint. She was taught traditional Chinese ink painting by the utterly inspirational Liu DaWei. Her time living in Hong Kong with its exciting blend of all things East and West became a main stimulus behind her artwork, particularly alongside her fascination with the symbolic role of pre-scientific beliefs in contemporary societies.
She became interested in the importance of biodiversity, which was the driving force behind her three picture books that were published in Hong Kong, written specifically for children there, and two of which were endorsed by WWF (Hong Kong). She has exhibited her artworks in Hong Kong, Beijing and the UK.
