1. Interannual rainfall variability over Guinea Coast, and the role of oceanic internal modes of
variability for different seasons, during the 20th century and the last decades
2. Evaluation of the representation of the boreal summer teleconnection between the Atlantic
equatorial mode of variability (Atlantic Niño) and the rainfall over the Guinea Coast

The goal of my research is to contribute to the rigorous analysis of elliptic two-dimensional integrable models along their combinatorial line. Over the years, these statistical mechanics models have been shown to exhibit rich analytic and algebraic structures, as well as surprising links to combinatorics. Yet, to this day, many of their aspects remain either conjectural or plainly unexplored. I focus my study on the eight-vertex model and related systems such as the 8VSOS model and the XYZ spin chain, as well as their higher-spin generalisations. One of my central aims is to address conjectures and open questions about the ground state of the XYZ spin chain along its combinatorial line for various boundary conditions. I am also interested in obtaining exact finite-size expressions for some interesting physical quantities. Ultimately, the analysis of their scaling limits for large systems will lead me to establish links with quantum field theory models in the continuum.
