Postdoctoral Researcher


I am a postdoctoral researcher at Princeton University’s Program in Atmospheric and Oceanic Science.

My research focuses on understanding, quantifying and anticipating the impacts of climate change on the ocean. The ocean provides a climate service by absorbing excess heat and carbon from the atmosphere, thereby slowing the pace of rising global temperatures. This service, however, comes at a cost - namely ocean acidification and ocean warming. My research identifies when and where changes in the ocean heat and carbon sinks occur, and when their resulting impacts on marine chemistry and ecosystems will be detectable. I utilize numerical models and observations of the Earth System to assess recent and predict future changes in the global oceans.

Sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone, a new study led by Princeton researchers finds. Meanwhile other impacts from climate change, such as changes in the activity of ocean microbes that regulate the Earth’s carbon and oxygen cycles, will take several more decades to a century to appear. The report was published Aug. 19 online in the journal Nature Climate Change.
