ACKNOWLEDGEMENTS I’ve been fortunate at Berkeley to work in a supportive and intellectually vibrant environment. Wayne Getz has taught me much about the practice and culture of science, and has set a powerful example by his integrity and humanism. Working with Wayne has been challenging, exciting and satisfying, and he has been incredibly generous with opportunities and his wholehearted support. Travis Porco has shared freely and graciously of his compendious knowledge of disease dynamics, and has shown me the beauty and pleasure in thinking a problem right through. Cherie Briggs gave me most of my training in ecology, as well as insightful guidance on matters of research, teaching and career. I thank Adam Arkin for our series of stimulating meetings, which I always left with my head brimming with new ideas. Joe Eisenberg provided excellent early training in disease modeling, and continued valuable advice over the years. I thank Udi Isacoff and the Berkeley Biophysics program for first drawing me to this great university, then granting me the freedom to discover and pursue a surprising new discipline. Shizuka Gannon, Diane Sigman and the Wellman office staff kept the bureaucrats at bay and otherwise softened the edges of institutional life. Away from Berkeley, Brian Williams has helped me to expand my research horizons to include global public health, and made possible a fascinating research visit at the World Health Organization. I’ve benefited greatly from collaborations with Sebastian Schreiber and Ekkehard Kopp, and separately with Alison Galvani. My day-to-day life at Berkeley has been shaped and greatly enhanced by my brilliant and eclectic peers. I’ve learned a tremendous amount from (and shared ii
