  孙天然博士简介:丹麦科技大学环境工程博士,美国康奈尔大学博士后。主要研究方向:自然存在的电子转移网络在土壤微生物代谢和矿物转化过程中的作用机制以及人为构建的电化学迁移网络在去除土壤重金属污染方面的应用。主要成就:(1)发现了有机质中热解炭的快速直接电子转移机制,突破了以氧化还原循环为电子转移主导的传统认识,研究成果发表于著名学术期刊Nature Communications ,并被美国科学促进会(AAAS)等多家科学媒体广泛报道;(2)针对热解炭的官能团和炭本体双重电子转移途径,开发了双界面电子转移捕捉的电化学新方法;(3)探索了快速电子转移机制对土壤微生物生长的影响,发现电容代谢新途径。近五年在Nature Communications , Journal of Hazardous Materials , ElectrochimicaActa等国际学术期刊发表SCI 论文10余篇。
