Brief bio: During my Ph.D. and now, my research field is plant hydraulic physiology, plant carbon and water balance. I studied with Nate G McDowell for one year at the Pacific Northwest National Laboratory during my PhD. My research focuses on: responses of plants to climate change, e.g drought, nitrogen deposition, sea-level rise; effects of climate change on plant water relations, xylem and leaf anatomy and gas exchange; the mechanism of plant stress resistance and mortality. In this study, we found that hydraulic and osmotic shifts during tree death under seawater exposure is related to the toxic effects of ion accumulation on maintenance of cellular function.

个人简介: 我在硕博连读期间主要致力于植物水分生理及植物碳水平衡的研究。博士期间在美国西北太平洋国家实验室(Pacific Northwest National Laboratory)联合培养一年，师从植物生态领域的知名学者Nate G McDowell。我主要关注植物对干旱、氮沉降、海平面上升等气候变化的响应;气候变化对植物水分关系、木质部和叶片解剖及气体交换的影响; 探讨植物抗逆性及其死亡机理。本研究主要揭示了海水暴露下树木死亡过程中水力和膨压的变化与Na⁺离子积累对细胞功能的毒性效应有关。
