Plant evolutionary ecology; geographic range limits and rarity; population dynamics and community structure.
Life cycle transitions of sexual eukaryote; Molecular mechanisms of nutrient sensing in phototrophic eukaryotes; Ubiquitin-dependent mechansism for chloroplast quality control; Evolution of developmental/epigenetic mechanisms; Macroevolutionary transitions from prokaryotes to eukaryotes and from green algae to land plants; Mitigating climate change by engineering algae for efficient carbon capture and biofuel production.
We investigate processes that underlie population and community responses to changing environments. Our current focus is on understanding and predicting community-wide responses to warming. We develop and test broad conceptual frameworks using laboratory and field experiments with insects and plankton communities.
