Research Interests

Ling Ren is currently working on diatom identification and enumeration in stream and river samples from various regions in the US, and using diatom data for water quality assessment. Her research also includes eutrophication, nutrient enrichment on phytoplankton growth and harmful algal blooms in estuarine and coastal ecosystems.


Ling Ren has conducted research work from Bohai and Jiaozhou Bay in Northeast China, the German Bight of the North Sea, and estuary of Northern Gulf of Mexico in Louisiana, involving field trips, meso- and microcosm experiments and modeling studies. She has collaborated with scientists from Zhejiang Ocean University (ZJOU, China) on a three-year project funded by Chinese Ministry of Science and Technology, on biodiversity in Zhoushan Fishery, East China Sea. She is also seeking for more research opportunities with ZJOU scientists to work on harmful algal blooms in relation to eutrophication and aquaculture in the same particular region of East China Sea. Ren had taught course of marine environmental science for a year in Ocean University of China (Qingdao) after she got her PhD. She also instructed undergraduates on research in marine science during her postdoc research. Last year while in ZJOU, Dr. Ren gave series of lectures on phytoplankton ecology to graduate students.
