Tom is a Professor of Biology, Curator of Fishes in the Museum of Southwestern Biology, and Associate Dean for Research in the College of Arts and Sciences at the University of New Mexico. He completed my PhD in 1996 at Florida International University in Miami Florida where he fell in love with the Everglades, the marine environment, and first became involved with conservation science in a serious way. Now, his research group at the University of New Mexico asks questions about ecological and evolutionary processes in aquatic environments -- mostly rivers, springs, and streams -- in arid lands. A major focus is the development of stable isotope methodology and analytical tools to uncover changes to community and ecosystem processes that accompany radical transformations of land, water, and climate over the last century. To do this, he uses time-series approaches based on the vast resources held in natural history museums.
