George’s research interests have focused on engineering interfaces between biological and synthetic components to develop nanocomposite materials and integrated devices/systems. Much of this work relies on motor proteins and cytoskeletal filaments as nanofluidic transporters in sensor devices and as “dynamic assemblers” of nanostructured materials. Additionally, my laboratory’s work involves isolating and engineering biomolecular components with functional handles that may be used to integrate DNA, proteins, lipids, and cells into hybrid assemblies. Genetic engineering techniques are also used to introduce new functionality or control into biomolecular components. Recently, we have begun work to establish fundamental correlations between the physical and chemical properties of engineered nanoparticles and the biochemical and biophysical response of membranes and cells.
