    演讲人简介:

　　Prof. Darryl Granger received his B.Sc. in Physics and Scientific Instrumentation from Carnegie Mellon University in 1991 and his PhD in Geology from University of California, Berkeley in 1996. His PhD thesis pioneered the way of using in-situ produced cosmogenic nuclides in alluvial sediments to measure the spatially averaged long-term erosion rates, which has now become a standard method of quantifying landscape erosion rates. He was also among the first to use cosmogenic nuclides to date sediment burial, burial dating with 26Al and 10Be opens up a new window to the world that has not previously been datable and has the potential to address many important problems in Earth sciences and archeology.

　　After receiving his PhD degree at Berkeley, Dr. Darryl Granger joined the Department of Earth and Atmospheric Sciences of Purdue University as an assistant professor in 1996, he became an associate professor in 2002 and has been a full professor since 2008. During this time, his professional interests has been applying cosmogenic nuclides to problems of landscape evolution, tectonic geomorphology, karst geomorphology, and archaeology, paleontology and paleoanthropology. He has also been a faculty member of Purdue Rare Isotope Measurement Laboratory(PRIME Lab), which is one of the only a few AMS laboratories in the world today with equipment capable of ultrasensitively measuring cosmogenic nuclides in geological samples.

　　Prof. Darryl Granger has been a Fellow of Geological Society of America since 2011.
