Research Interests

My research interests are in Environmental Modelling and Statistics for the Marine Sciences. They include:

  • State Space Models and Data Assimilation :
    I have an ongoing research interest in data assimilation, i.e. combining nonlinear dynamical models with available observations to produce optimal estimates of the time evolving system state and model parameters. This involves linking statistical estimation theory to the problem of fitting dynamical models (governed by time and space dependent partial differential equations) to observations. My recent research involves statistical approaches for the data assimilation problem. These rely on the nonlinear, nonGaussian state space model and use Monte Carlo based Bayesian computational methods for data-model fusion These ideas have been applied to marine prediction, considering both the complex dynamical behaviour, as well as the high dimensionality found in practical applications. A current application area is ocean carbon dynamics in the NW Atlantic.

  • Stochastic Marine Ecosystem Modelling :
    Another research area I have is in the development of mathematical models for lower trophic levels of marine ecosystems. Currently, I am considering stochastic versions of such ecological models for uncertainty qunatification, as well as Bayesian approachs to combining them with new types of observational data. This work has been focused on development and application of differential equation based models of coastal ecosystems with current work in seagrass ecosystems.

  • Data Analysis Methods for Marine Environmental Observations :
    I also have a general interest in the development and application of statistical analysis techniques for marine environmental data sets. Current work includes reconstruction of long term ocean time series, and marine animal movement modelling and signal processing for accelerometer data.
