Juan B. Arellano has been a researcher at the Institute of Natural Resources and Agrobiology of Salamanca (CSIC) since 2001. He received his PhD degree in Chemistry at the University of Granada (Spain) in 1994. Since then, his research has been focused on electron and energy transfer in plant photosynthesis and plant defense responses to abiotic stresses. His knowledge in photosynthesis started in the 1990s at the Experimental Station of Zaidín (Granada, CSIC), where he worked on photosystem II inhibition by copper, and continued at the Universities of Glasgow, Umeå, Girona in the middle of the 1990s, where he stayed as a postdoctoral fellow working on energy transfer in antenna complexes and the role of carotenoids in photoprotection against singlet oxygen. At present, his research deals with the physiological and biochemical response of cereal plants to global climate change. He is a member of two Spanish societies: SEBBM and SEFV.
