Hi! I am a keen field naturalist who delights in observing and understanding wildlife, however big or small. I have broad interests in many aspects of environmental science, with particular interests in ecology, natural history, and the determinants of species’ distributions. I have worked primarily with amphibians since 1991, in Victoria and Queensland, Australia, and here in Arizona, USA. In Australia, I participated in three main areas of research: 1) identifying the determinants of tadpole distributions along tropical rainforest streams (PhD dissertation), 2) observing and understanding the population dynamics of stream-dwelling amphibians, and 3) understanding the causes of frog declines in upland rainforest. Since 1998, which includes my time at ASU, I have been particularly interested in understanding the role of the amphibian chytrid fungus, Batrachochytrium dendrobatidis, in frog population declines that have occurred worldwide in recent decades. While at ASU, I have worked closely with Verma Miera, Prof. James Collins and Dr Elizabeth Davidson on the disease ecology of B. dendrobatidis and its impact on the frogs and salamanders that occur on the Mogollon Rim in north-eastern Arizona. While not at work, I like to spend time with my family, and indulge my interests in travel, photography, cycling, and fine wine, food and music.
