Yongmei Ma received her PhD in January 2016 from the Hefei Institute of Physical Sciences, Chinese Academy of Sciences. Since April 2016, she has been working at Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences. Her research interests include detection, monitoring, and source analysis of organic pollutants in water by spectral technology, photocatalyst degradation. Effects of land use and human activities on the source, composition, and optical characteristics of river DOM. The influence of DOM on heavy metal migration and transformation and its potential mechanism. Driving mechanism of dissolved carbon cycle in rivers and lakes. Her research has been supported by the National Natural Science Foundation of China, General Project of Chongqing Natural Science Foundation, and Project of Chinese Academy of Sciences. She has coauthored over 20 papers in peer reviewed international journals such as Water Research, Analytical Chemistry, Journal of Hydrology, Journal of Materials Chemistry A, Environmental Research, including 14 SCI papers as the first author. She won research projects for talents, including Youth Innovation Promotion Association and West Light Foundation of the Chinese Academy of Sciences.
