In his first lecture, Dr. Edwards explains that studying gene alleles within different populations or species allows the construction of gene trees showing how the groups are related. The gene trees can be used to link genetic variation to geographic distribution of populations; the study of phylogeography.
In Part 2, Edwards expands his discussion of phylogeography with a focus on Australian songbirds. Edwards changes gears in Part 3, and describes studies from his lab investigating the recent evolution of resistance to the parasite Mycoplasma in House Finches and the co-evolution of genetic changes in Mycoplasma.
Scott Edwards pursued his undergraduate studies at Harvard and was a graduate student at the University of California, Berkeley. He began his research on Babbler songbirds in Australia while he was a graduate student. During his post-doc at the University of Florida, Edwards switched the focus of his studies to immunogenetics and population genetics in wild birds. He became an Assistant Professor at the University of Washington in 1994 and in 2003 he moved to Harvard University. Currently, he is Professor of Organismic and Evolutionary Biology and Curator of Ornithology in the Museum of Comparative Zoology at Harvard.
Edwards is proud to include undergraduate and graduate students in his research and is actively engaged in increasing student diversity in evolutionary and environmental sciences.
