 In collaboration with El-Hani, João Queiroz has developed extensive work on the biosemiotic approach to biology (El-Hani, Queiroz, and Stjernfelt 2010; Queiroz, Emmeche, Kull, and El-Hani 2011; Queiroz 2012; Queiroz, Stjernfelt, and El-Hani 2014), and its relationship with genetic information (El-Hani, Queiroz, and Emmeche 2006). From a completely different viewpoint, Suárez-Díaz (2007) discusses what she considers the metaphor of information in molecular biology.
