Laser tweezers; Regulation of molecular motors – My research is quite cross-disciplinary. The majority of biological studies have focused on biochemical or genetic understanding of biological processes, however understanding the relevant physical processes is also important. Proteins physically do things, and to understand the biology, we must start to think about proteins as machines, as well as considering their biochemical properties and genetic regulation. We will soon know the Human Genome, we already know the Drosophila and the C. Elegans Genomes, and yet are very far from understanding how proteins work, and how the exquisitely ordered structures we observe in cells, embryos, and developed organisms come about. Cytoskeletal processes such as transport are important in the creation of this order, and my lab is attempting to develop and apply physical tools to quantify transport as it occurs in living cells.
