Humboldt State University (HSU) is a comprehensive public university with world-class graduate programs in natural resource management, located on the North Coast of California, in a beautiful, remote setting. The Mathematical Modeling option of the Environmental Systems Graduate Program at HSU has an active research program in various applications of mathematics and statistics to environmental problems. Thematic research areas include the quantitative study of (1) biodiversity and conservation through population ecology, fisheries biology and forest fire modeling; (2) interactions between the environment and individuals or populations; and (3) physical and biological understanding of climate change and its consequences. For a detailed list of research activities please visit our website at http://www.humboldt.edu/~envsys/math/. The program is distinguished by its low student-to-faculty ratio, high level of faculty mentoring and interdisciplinary curriculum. We are looking for qualified applicants who are interested in broadening their mathematical skills and applying them to problems in the environmental and natural resources sciences. Our graduate students typically hold a bachelors degree in pure or applied mathematics, but other applicants with a strong quantitative background will also be considered. Applications are due March 15, 2009. For more information regarding applications please contact Dr. Bori Mazzag (bo...@humboldt.edu).
