Yuyuan joined the Milford Lab as a Postdoc in November 2018 through the Research Associate Program of the National Research Council. He will continue his work on chlorophyll fluorescence and a technique for the inversion of photosynthetic processes. The project aims to model the non-photochemical quenching by sunlight cycles to achieve more accurate chlorophyll a estimates by in vivo fluorescence in the environment and culture systems. Yuyuan plans to study how cell size (one of morphologic properties) or genetic divergence of algae species affect the model, and he will facilitate the research by bringing in marine optics tools. Yuyuan is looking forward to the deliverables of this project, which will aid ongoing efforts to improve the water quality of Long Island Sound.

Yuyuan has studied marine primary productivity for many years, and has spent a total of more than a year at sea collecting data. He published papers interpreting that field data, focusing on the relationship between primary productivity and the composition of phytoplankton functional groups. While we understand the environmental controls on primary production, we don’t understand the morphologic and genetic mediation of algal physiology well enough, and this has often been overlooked. This mediation is connected to many subtle changes inside the cells which are vital for phytoplankton to adapt to their habitats. Moreover, this knowledge is essential for us to gain insights into the observational field data by which we understand the nature.
