Dr. Walker’s research focuses on climate and sea-level change on short-term instrumental to long-term geological timescales to improve understanding of past sea level in order to better predict sea-level rise into the future. She specializes in reconstructions of sea-level through time using biological and geological indicators, which when combined with statistical modeling techniques, are used to quantify rates of sea-level change and examine spatial and temporal variability of driving processes.
