Katie Scott (Illustrator)
Katie Scott graduated from University of Brighton in 2011. Her work draws influences from traditional medical and botanical illustration, both in aesthetic and subject matter, and plays with the ideas of scientific uncertainty and speculation, fabricating the inner and outer workings of the world. Her illustrations depict a familiar yet fantasy vision of plants, humans and minerals.
