Gassan Hodaifa Meri Food Engineer (Albaath University, Syria), Chemical Engineer (Granada University, Spain) and Dr. by University of Jaén (Spain) in the Doctoral Program: Biotechnology and Agricultural Engineering. His research began in the year 1997 with a Doctoral Scholarship to perform in Spain, has joined to the research group “Bioprocesses TEP-138†(Government of Andalusia) and he work in the investigation lines of Biotechnology of Microalgae, Industrial and Urban Wastewater Treatment, Chemical Oxidation, Membrane Technology, Adsorption processes, Pesticides Removal, and Biotechnology of Enzymes. Biotechnology of microalgae is of great interest to the industry as a source of food, biofuels, pharmaceutical production, application in bioremediation, CO2 sequestration (greenhouse effect) ... After the experimental part of his Doctoral Thesis (2002) he worked with the group “Chemical Processes and Agri-Food Technology TEP-807†(Government of Andalusia), to develop a new technology for olive oil mill wastewaters (from two-phase decanting process) treatment. Currently participates in developing a new line of research entitled “Nematode biomass production in bioreactors†in collaboration with the Genetics area of Pablo de Olavide University. Participated in 17 research projects (European, National, regional, and with companies), with which it has signed several contracts for research. As a result of this research activities has been published 40 articles in journals included in SCI, 1 patent, 2 books, 19 book chapters, and has participated in 73 Congress are most international first class in scope. He has designed, installed and automated Industrial Pilot Plant of Wastewater Treatment for olive-oil mill wastewaters from two phase decanting process with daily treated water capacity 3-5 m3/h. It has been repeatedly Associate Professor (University of Jaén), and Assistant Professor at the University of Jaén (05/06) and the Complutense University of Madrid (06/09). Now he works in Pablo de Olavide University, Seville (Spain) in the Molecular Biology and Biochemical Engineering Department/Chemical Engineering Area as Lecturer.
