Lawrence R. Walker is a professor of plant ecology at the University of Nevada, Las Vegas. His research focuses on the mechanisms that drive plant succession after natural and anthropogenic disturbances including cyclones, volcanoes, landslides, mine tailings, and abandoned roads. These disturbances are located in tropical, temperate, boreal, and arctic biomes. He also studies the management of disturbances through restoration. Walker emphasizes comparisons across environmental gradients and many different types of disturbances, searching for useful generalizations about disturbance ecology, succession, and restoration. He has over 115 scientific publications, including seven books, has won several research awards, is co-editor of a book series, and is an ISI highly cited researcher.
