1968年6月生，江西吉水人。1989年获南京大学地球科学系学士学位。1992年获南京大学矿物学硕士学位。2001年获中国科学院广州地球化学研究所矿物学博士学位。1992年开始在中国科学院广州地球化学研究所工作至今。2013年起任矿物学与成矿学院重点实验室研究员。

长期从事高压矿物学方面的实验研究工作。主要依托金刚石压腔(diamond anvil cell, DAC)高压装置和激光显微加热技术，模拟地幔、特别是下地幔温压条件，结合同步辐射先进光源、显微Raman光谱等高压原位测量技术，开展地球物质高压新相合成和结构解析、地幔矿物典型结构和高压相变、元素高压晶体化学行为等研究，探讨地球深部物质存在状态、性质、变化及其可能的地球深部物理化学响应。近年来，主要专注于钙钛矿结构化合物高温高压合成及其多形相变的物理化学机制研究，首次发现立方钙钛矿结构压致等结构相变现象，并发现多个高压新相。
