Nonlinear filtering of high dimensional, chaotic, multiple timescale correlated systems
… filtering theory for high dimensional, chaotic, multiple timescale correlated systems. The research is motivated by problems in the geosciences, in particular oceanic or atmospheric estimation and climate prediction. As the capability and need to further resolve the physics models on finer scales …

Rate-induced tipping to metastable Zombie fires
… due to crossing an elusive quasithreshold, in a multiple-timescale dynamical system. The instability is {\em reversible}, in the sense that the system eventually returns to its base state. To explain this instability, we provide a framework that combines a special compactification technique with …

Planet formation, resonant drag instabilities, and vortices
… differ substantially from disc flows. I use a multiple-timescale analysis in the regime of well-coupled grains to derive the first analytical model for dust-laden vortices in protoplanetary discs. I find that if the vortex is weak and anticyclonic, dust drifts towards its centre. Since the dust …
