Sal Agosta is an Associate Professor, Virginia Commonwealth University. He received a PhD in Biology from the University of Pennsylvania in 2007, after which he was awarded a Postdoctoral Fellowship in Ecology and Evolutionary Biology from the University of Toronto followed by a Howard Hughes Medical Institute Postdoctoral Fellowship from Wilkes University. Sal is an ecologist and evolutionary biologist whose work ranges from field and laboratory studies of animal-plant interactions in both temperate and tropical habitats to theoretical studies of foundational concepts in ecology and evolution. His current research focuses on the physiological ecology of plant-feeding insects, particularly in the context of biological invasions and climate change. Daniel R Brooks is Professor Emeritus, University of Toronto. He is a Fellow of the Royal Society of Canada (Academy of Science) and Fellow of the Linnaean Society of London and has been awarded honorary doctorates fromStockholm University and the University of Nebraska. He has been a Senior Visiting Fellow of the Collegium Budapest, Stellenbosch Institute of Advanced Study,Institute of Advanced Studies, Köszeg, and the Hungarian National Institute of Ecology. Dan is an evolutionary biologist whose more than 375 scientific publications, including half a dozen books, ranges from field studies of the evolution of host-pathogen systems in tropical wildlands to foundational studies of evolutionary theory. His current focus is integrating evolutionary principles into developing proactive public policy for coping with global climate change, with an emphasis on the emerging disease crisis.
