I am a fisheries oceanographer investigating ecosystem responses to climate variability and change. This research involves consideration of theory, observations (time series and process studies), and models.

My research group works to understand the impact of climate processes--both natural and anthropogenic--on fisheries and ecosystem productivity. By investigating the influence of physical processes on nutrient composition, the carbonate system, oxygen content, and the structure of planktonic assemblages, we hope to better understand the implications of long-term climate changes for the productivity of living marine resources.

We seek to understand the responses of marine ecosystems and fisheries to climate variability while sharing our passion for oceanography and exploration.


Relocation to the NOAA Pacific Islands Fisheries Science Center:
In fall of 2019, the lab migrated from South Carolina to the NOAA Pacific Islands Fisheries Science Center in Honolulu, Hawaiʻi, allowing increased focus on the dynamics of ecosystems of the North Pacific and their interactions with climate processes.

Current opportunities:

Graduate Student Positions:
Although the lab is not currently accepting new students, opportunities may be available in the future through the graduate program at the University of Hawaiʻi at Mānoa.

Undergraduate student positions:
If you have an interest in opportunities for undergraduates at the Pacific Islands Fisheries Science Center or at the University of Hawaiʻi, please contact me for more information.
