Dr. Liu has served on various international and national committees and panels. He is president of the U.S. Regional Association of the International Association for Landscape Ecology (US-IALE). In recognition of his efforts and achievements in research, teaching, and service, Dr. Liu has received many awards, such as being named a Fellow of the American Association for the Advancement of Science (AAAS), Guggenheim Fellowship Award, CAREER Award from the National Science Foundation, Distinguished Service Award from US-IALE and the Aldo Leopold Leadership Fellowship from the Ecological Society of America.
