基本信息
2000年作為英國皇家學會皇家學者在利物浦大學合作研究；2001年7月受訪問獎研金資助在美國明尼蘇達岩石磁學所工作；2003年作為德國洪堡學者在慕尼黑大學地球物理所和波茨坦國家地學中心合作研究。曾獲得1999年中國科學院青年科學家二等獎；2002年中國地球物理學會青年科技獎。主持或參加過多項國家自然科學基金委、科技部和中科院資助研究項目。2004年獲得國家基金委傑出青年基金項目資助。1998年以來，在《J. G. R.》、《G. R. L.》、《GJI》、中國科學等國內外刊物發表論文, 被SCI收錄38篇；被SCI刊物引用愈百次。
主要研究方向
主要從事岩石磁學、地球磁場古方向和古強度變化、生物地磁學和環境磁學等套用的基礎性研究。（1）生物成因磁性礦物對剩磁記錄影響和古環境意義：與德國科學家合作，揭示出磁細菌化石磁小體是德國南部湖泊碳酸鹽沉積物的主要磁性來源;（2）礦物和岩石磁性：從實驗角度研究各種岩石和沉積物中磁性礦物特徵，形成和相互轉換，它們對古地磁和環境磁學記錄的貢獻。例如，揭示了菱鐵礦熱分解氧化經歷了由磁鐵礦和磁赤鐵礦向赤鐵礦的轉變過程和磁性質變化，有助於識別加熱引起的礦物變化何時和如何影響古地磁實驗和數據解釋;（3）地球磁場相對古強度和高解析度磁性地層研究：利用中國黃土沉積序列研究地球磁場相對強度變化。通過末次冰期黃土的相對古強度研究，拓寬了現有相對古強度研究材料；實驗揭示出了1.2百萬年以來黃土層至少記錄了七個地磁漂移事件, 從實驗角度證明了黃土具有記錄高解析度地磁場方向變化的能力;（4）地質歷史時期地球磁場絕對古強度研究：古強度記錄是探索和建立地球動力學模型的重要約束條件之一，利用不同方法確定火山岩記錄的絕對古強度。
工作構想及研究條件
探索生物與地球磁場的聯繫是富有挑戰性和創新性的研究領域。受國家自然科學基金委傑出青年基金資助，針對我國不同氣候帶典型湖泊和土壤沉積物中磁細菌和生物成因磁性礦物，利用現代岩石磁學方法，開展沉積物的生物磁學研究：建立化石磁小體的岩石磁學識別標準；研究磁細菌和化石磁小體對沉積剩磁的貢獻和其環境指示意義。同時，與國內外生物學家合作，開展生物與變化外磁場關係研究，以及探索生物磁信號接收器，為探討生物與地球磁場聯繫積累基礎資料。所在研究所擁有國際水平的岩石和礦物磁學測試儀器，“零磁”空間、變梯度磁場和變極性磁場線圈、磁細菌分析系統等設備，另外還擁有先進的透射電子顯微鏡等, 能夠滿足研究所需實驗和觀測條件。
