Christopher Wood is one of the world s foremost experts in fish physiology. Over the past 25 years, he has conducted field studies from China to Brazil. His field research and laboratory studies have shown that fish are surprisingly resilient in adapting to changes in their environment. His laboratory studies have uncovered new knowledge about the most important organ in a fish its gills. At one time, the gills of a fish were thought to act only as the lungs. Research has shown that the gills combine the functions of a human s kidney and digestive tract. How metals pass through or are absorbed by the gills is at the heart of Wood s research.LINK TO ACESS HOME PAG OF CV: http://www.science.mcmaster.ca/woodcm
