Research Contents : His scientific interests focus on the geological application of rock-, environmental-, and paleo-magnetism. He investigates different types of synthetic magnetic minerals to determine their magnetic properties and underlying mineral magnetic mechanisms. He systematically investigates aeolian dust signals recorded by the Chinese loess (related to Asian summer and winter monsoons) and by marine sediments from the North Pacific Ocean (related to westerlies) by integrating different methods. He is also interested in constructing chronological frame for marine sediments. His recent studies involve in investigating the striped magnetic anomalies in the ocean floor and paleoceanographic conditions of the North Pacific Ocean.
