Dr. Felipe Barros, qualified as a Medical Doctor at the University of Chile in 1988, and obtained a PhD from the same university in 1993, advised by Dr. David Yudilevich. From 1993 to 1996 he was a Wellcome Trust Fellow in Steve Baldwin´s lab at the University of Leeds, UK, returning in 1996 to the University of Chile as Assistant Professor and then Associate Professor. In 2000 he joined the Center for Scientific Studies in Valdivia, where he is now a principal investigator. Dr. Barros and his group address the question of how the flux of energy relates to the flux of information in cells and in the brain. To elucidate these questions his team is developing new techniques to measure metabolic parameters using fluorescence microscopy.
