Enrique Vivoni - a hydrologist, senior sustainability scientist and associate professor at Arizona State University - is one of 20 recipients awarded a 2015 Leopold Leadership Fellowship. Vivoni's scholarship in the area of shared resources led to his selection for this prestigious fellowship program, which endeavors to communicate scientific research to a wide audience.

Water in the southwestern United States and northern Mexico is a contentious issue that traverses disciplinary boundaries. Vivoni’s research activities focus on the intersection of hydrology and its allied disciplines - ecology, meteorology and geomorphology - in order to improve our understanding of water resources in this region. The collaborative studies on shared water between the United States and Mexico that Vivoni facilitated are a hallmark of his research achievements.
