I am recognized as an international authority on concepts, patterns, measurement, and modeling of biodiversity, including the effects of climate change on biogeographical patterns in the past and the future, especially in the tropics. My work with biogeographical theory and stochastic spatial models has stimulated controversy and new directions in the field, with links to evolutionary biology and conservation. My publications have been cited more than 45,000 times in the peer-reviewed literature, in more than 800 different journals and hundreds of books. I served on the faculties of the University of California, Berkeley until 1989, and at the University of Connecticut until 2014. I am an elected Fellow of the American Academy of Arts and Sciences and the California Academy of Science, and Connecticut Academy of Science and Engineering. In addition to my (emeritus) title at the University of Connecticut (Distinguished Research Professor), I also hold current appointments at the University of Colorado (USA), the Universidade Federal de Goiás (Brazil), the University of Copenhagen (DK), and the University of the Sunshine Coast (Australia).
