Research

My lab is interested in studying dynamic complexes and processes in natural and bio-synthetic membrane architectures.  Our efforts in natural systems focus on investigating light-harvesting  (LH) and energy transfer mechanisms in green photosynthetic bacteria.  These bacteria utilize a unique light-harvesting complex, called the chlorosome, that relies heavily on mechanisms of self-assembly, devoid of protein scaffolds, unlike other LH systems.  The unique structure and remarkable light-harvesting capability of these complexes make them model systems for investigating energy transfer phenomena.  We use molecular and cellular biology techniques to modify the natural systems and biochemical and biophysical techniques to investigate effects on light-harvesting and energy transfer function.  Synthetically, we are interested in investigating membrane dynamics in phospholipid and block copolymer based assemblies.  Our focus is on exploring how we can predict and control nano-bio interactions in membrane assemblies to create new dynamic materials.
