Helga Huntley studies pieces of the Earth's climate system by using mathematical and numerical models, in connection with data. The mathematics involved ranges from PDE theory to numerical methods to optimization theory to statistics.
She is currently following three main directions in her research: (1) Developing and applying Lagrangian tools to analyze ocean circulation and transport; (2) Investigating data assimilation methods (for paleoclimate reconstruction, e.g., and for Lagrangian observations); (3) Studying sea ice in the Arctic and its role in the local circulation.

Lagrangian Ocean Dynamics
The broad question we try to answer is "Where is stuff in the ocean coming from and where is it going?" This line of inquiry has lots of interesting applications, from pollution mitigation and search and rescue missions to biology to tracer transport in the context of climate dynamics.
Huntley’s work on data assimilation has taken two main directions. One is related to the Lagrangian ocean dynamics analysis and studies how Lagrangian observations (e.g. from surface drifters) can be used to improve Lagrangian forecasts. The other branch is concentrated on the problem of using data averaged over time to inform a model with higher temporal resolution.
Sea Ice Dynamics
Currently, Huntley is working on using ice models in conjunction with observations to understand the seasonal cycles in ice-ocean dynamics in the Canadian Archipelago.
