Research Interests

Plant Cell Wall Research

My colleagues and I focus our research attention on aspects of plant development in which plant cell wall metabolism plays an important role. This includes studies of fruit ripening and the interactions of pathogens and insect pests with plants. In recent years our studies have also included aspects of cell wall disassembly that might be controlled and enhanced in order to optimize the generation of biofuels from crop plant "residues".
