Christopher D. Moyes received his Ph.D. in Zoology from the University of British Columbia in the area of comparative muscle physiology. After postdoctoral fellowships in molecular physiology at the U.S. National Institutes of Health and Simon Fraser University, he took a position at Queen's University, where he is an associate professor in the Department of Biology. He teaches a spectrum of courses in cell biology and animal physiology, while continuing to pursue his research interests in molecular physiology and biochemistry.Chris is a recipient of the Premier's Research Excellence Award. He is a member of the American Physiological Society and The Canadian Society of Zoologists and has… served on the Natural Science and Engineering Research Council of Canada grant panel for Animal Biology. He is also a member of the Editorial Board of "Comparative Biochemistry and Physiology," He has published more than 60 peer-reviewed papers, including contributions to four books. Among his recent papers are Moyes, C.D., and D.L. Hood (2003) "Origins and consequences of mitochondrial variation in vertebrate muscle," "Annual Review of Physiology" 65: 177-201 and Moyes, C.D. (2003) "Controlling muscle mitochondrial content," "Journal of Experimental Biology" 206: 4285-4391.Patricia M. Schulte received her Ph.D. in Biological Sciences from Stanford University in the area of evolutionary physiology focusing on the role that changes in gene expression play in evolution. She is currently an assistant professor in the Department of Zoology at the University of British Columbia in Vancouver, where she teaches animal physiology and evolutionary physiology and runs an active research program. Usingseveral species of fish as model systems, her research group is particularly focused on the relationship between genetic variation, performance differences, and fitness in a changing environment. She also conducts research into applied questions relating to fisheries, aquaculture, and aquatic toxicology.Trish is a recipient of the Premier's Research Excellence Award and several teaching awards, including the UBC Science Undergraduate Society Award for Excellence in Teaching. Trish is a member of the Canadian Society of Zoologists and the Society for Integrative and Comparative Biology. She is an associate editor for the scientific journal "Physiological and Biochemical Zoology,"She has published more than 30 peer-reviewed papers, including two book chapters. Among her recent papers are DeKoning, A. B. L., D.J. Picard, S.R. Bond, and P.M. Schulte (2004) "Stress and interpopulation variation in glycolytic enzyme expression in a teleost fish, "Fundulus heteroclitus,"" and P.M. Schulte (2003) "Na+/K+-ATPase alpha-isoform switching in gills of rainbow trout "(Oncorhynchus mykiss)" during salinity transfer," "Journal of Experimental Biology" 206: 4475-4486.
