Research

My laboratory applies physiological, biochemical and molecular biological approaches to study metabolism, nutrition, and cell physiology in plants. An integrative approach is taken whereby processes are studied at the whole plant, cell, organelle and molecular level. Nicotiana tabacum and Arabidopsis thaliana are used as model plant species for these studies. Interests include mitochondrial electron transport and the alternative oxidase, respiratory carbon metabolism, nitrogen and phosphorus nutrition, environmental and stress physiology, mitochondrial stress responses, oxidative stress, anaerobic metabolism, plant cell death mechanisms, terminal oxidases in cyanobacteria and marine invertebrates, plant-pathogen interactions, and comparative approaches to cellular energetics.
