Miquel Ribas-Carbo. Associate Professor at the Department of Biology of the University of the Balearic Islands (Universitat de les Illes Balears) in Palma de Mallorca, Spain. He received his Ph.D. from the University of Barcelona in Spain in 1993, with a thesis on 'Regulation of plant respiratory mitochondrial electron transport', under Joseph A. Berry and J. Azcón-Bieto. From 1994 to 1995, he was a Fulbright Postdoctoral Fellow at the Department of Botany of Duke University, USA, with Jim Siedow and a in 1996 to 1997 he was a researcher at the University of Navarra, Spain. From 1998 to 2001 he was a Research Associate at the laboratory of Joseph A. Berry at the Department of Plant Biology of the Carnegie Institute of Washington, Stanford, California. Miquel Ribas-Carbo's research has mostly focused in studies of the regulation of the mitochondrial electron transport between the cyanide-sensitive cytochrome pathway and the cyanide-resistant alternative pathway. The development and improvement of the oxygen-isotope technique to study plant respiration electron partitioning has been, and still is, one of his major research objectives. In 1997, he received the Spanish Society of Plant Physiology Award for Young Scientists.
