Research Interest
I have strong interests to do an interdisciplinary research in oceanography field towards understanding the physical processes on estuarine and coastal environments, which are highly influenced by human activities.
During my Ph.D. dissertation, I used both statistical (regression) and numerical models (ROMS) to study the influence of anthropogenic and climate factors on the hypoxic area variability in the Gulf of Mexico. I found that the increased hypoxic area in the Gulf of Mexico was caused by the increased anthropogenic nitrogen loading of the Mississippi River; however, the nitrogen-area relationship is complicated by many other factors, especially wind. The upwelling favorable wind is important for hypoxic area development. However, a long duration of upwelling wind decreases the area.
Right now, I am working with Marjy Friedrichs (VIMS) and John Wilkin (Rutgers) towards developing coupled physical-biogeochemical model to understand the role of estuaries in global carbon cycle.
