Ester Gaya is a senior research leader at Royal Botanic Gardens in Kew, England. She began her career in mycology in Spain and lived in the US before settling in the UK. She has spent the past twenty years researching fungi and is especially fascinated by lichens and their evolutionary process. Katie Scott graduated from University of Brighton, England. Her work draws influences from traditional medical and botanical illustration, both in aesthetic and subject matter. It also 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.
