Research Interests
Evaluating global and regional sea level variations from satellite and in-situ observations:
What are the contributions to global and regional sea level change from steric and non-steric sources, dynamic sea level adjustments, and so-called "sea level fingerprints"? How are these evolving over time?
Tracking Earth's energy budget and ocean heat content from satellite gravimetry and altimetry
Where does the increasing ocean heat go? What role does the deep ocean (below 2000m) play?
Earth's water cycle & associated surface mass redistributions:
How can we best utilize tools from hydrogeodesy to measure water availability (e.g., aquifer storage, drought monitoring, etc.) & develop applications of satellite observations to aid with water resources & coastal impacts management?
Earth rotation and center of mass variations due to atmosphere-ocean-land interactions;
Assessing observations & Earth System Model simulations: rates and patterns of sea level variability & trends and their drivers;
