罗亚威博士建立了第一个海洋固氮数据库(Earth System Science Data 4:47-73),该数据库已经被其他科学家广泛使用,被Web of Science列为高引用论文。通过MEL这个优秀的平台,罗老师同各个领域各个实验室的科学家合作,通过定量手段加深科学认识。例如,罗老师近期和我实验室史大林教授合作,针对全球海洋中重要的固氮生物——束毛藻——建立了单细胞尺度模型,模拟细胞能量及铁的最优化分配。该研究为束毛藻对海洋酸化存在负响应提供了又一有力证据:束毛藻从CO2浓度上升获得的收益,远远低于海水pH降低产生的负效应。进一步地,将此单细胞模型与地球系统模型预测的未来全球海洋CO2浓度及pH值结合,估计出:在RCP8.5场景下,全球束毛藻固氮潜力在本世纪内平均将会减少27%Nature Communications 10:1521)。




Dr. Ya-Wei Luo is an associate professor of oceanography at the State Key Laboratory of Marine Environmental Science. He joined Xiamen University in 2013 after several years of postdoctoral experience at Woods Hole Oceanographic Institution’s Department of Marine Chemistry and Geochemistry. Before that, he obtained his Ph.D. from a joined program of Brown University and Marine Biological Laboratory in ecology. Dr. Luo has a multidisciplinary education background, also holding a Master degree of atmospheric physics from Peking University and a Bachelor degree of fisheries from Ocean University of China.

Dr. Luo’s interests lie in “marine microbial biogeochemistry”, which is an area studying how microbial (mostly single-celled) organisms interact with ocean environments to mediate recycles of biogenic elements, such as carbon, nitrogen, phosphorus and iron, and to a broader context how the processes can impact the global climate. Particularly, his research focuses on diazotrophic bacteria in mediating N2 fixation, heterotrophic bacteria in interacting with dissolved organic carbon, and viruses in controlling death of bacteria in the ocean.

Unlike most of other scientists in this area, Dr. Luo carries out his studies on computers. Those include syntheses and analyses of observational and laboratory data using statistical or machine learning methods, and constructing numerical models to simulate marine systems in different scales.

Dr. Luo established the first oceanic N2 fixation database (Earth System Science Data 4:47-73) which has been widely used by other scientists. It is ranked as a “Highly Cited Paper” by the Web of Science. On the excellent platform of MEL, Dr. Luo is able to work with field- or laboratory-based scientists to quantitatively improve the understandings. For instance, he recently collaborated with Dr. Dalin Shi, a Professor at MEL, and constructed a single-cell level model for a globally important oceanic N2 fixer, Trichodesmium, simulating optimal allocation of cellular energy and iron. The study provides additional quantitative evidence that the N2 fixer response negatively to ocean acidification: the cellular energy saved from increasing CO2 is very small compared to the negative effects from lowered pH. By further running the single-cell model with CO2 and pH predicted by Earth system models, it estimates that under RCP 8.5 scenario the N2-fixing potential of Trichodesmium can decrease by 27% in the global ocean by end of this century (Nature Communications 10:1521).

Dr. Luo actively contributes to various of services in MEL. He is the Local Organization Committee Chair of the Fifth Xiamen Symposium on Marine Environmental Science (XMAS). The XMAS is a biannual conference series which has grown to one of the Asia’s largest conferences in oceanography ( He is the Committee Chair of MEL’s Undergraduate Research Internship Program, in which tens of undergraduate students from the World are selected each summer to conduct scientific trainings at MEL ( Dr. Luo is also the vice Chair of Department of Marine Biology and Biotechnology in managing the Department’s undergraduate education. He also leads the College of Ocean & Earth Sciences (COE)’s Honor Program, in which special courses and laboratory opportunities are arranged for <10% of COE’s undergraduate students who have strong interests in scientific research.
