Cristina Gonzalez-Fernandez received her PhD degree in Chemical Engineering and Environmental Technology at the University of Valladolid (2008). She carried out her doctoral thesis in the field of livestock wastes treatment for the removal of organic matter by means of mechanical and photosynthetic oxygenation on the liquid matrix and biogas production on the solid matrix. Previously to that, she worked at the Environmental Engineering Department in the University of Cincinnati (USA) where she also obtained a Master on Environmental Science (2005). She got a postdoc position at the Biotechnology Lab in the French National Institute for Agricultural Research (LBE-INRA, France) to work on the optimization of biogas production using microalgae. Nowadays, her research is focused on the recovery of carbon from wastes via biotechnological means. She is co-author of around 100 scientific publications and reviewer of international journals. Additionally, she has been involved in European and national funded research projects, as well as projects with private companies. She has supervised 5 PhD Thesis, and 20 Master Thesis and Final Year Projects. Today, Cristina González is Associate Professor at the Dept. of Chemical Engineering and Environmental Technology of Valladolid University.
