Welcome to Oscar Feng-Hsun Chang's lab

The primary aim of our lab is to explore predator-prey interactions and their broader impacts on marine ecosystems. These interactions, encompassing the growth and grazing mortality of both predator and prey, not only shape community diversity but also play a critical role in regulating various ecosystem functions vital to human well-being.

Our approach involves conducting manipulative experiments aboard research vessels and utilizing advanced statistical analyses to unravel the complexities of predator-prey dynamics and their ecological consequences. Currently, our research is centered on investigating predator-prey interactions within marine planktonic food webs. We seek to understand how these trophic relationships influence plankton diversity, energy fluxes, and the cycling of essential nutrients within marine ecosystems.
