John is a glaciologist interested in how ice dynamics respond to both stochastic climate variability and long-term forcing. He uses ice-flow models spanning a range of complexity, alongside analysis of glacier and climate records. John is working with Prof. Ginny Catania’s group, and his main project is using model ensembles to understand the causes of unstable outlet-glacier retreat in the presence of natural climate variability and anthropogenic forcing. More generally, John is also interested in model calibration and initialization, and understanding these challenges in the context of a rapidly changing cryosphere.
