Technical Research Interest:

Research in the Tolbert group is focused on controlling nanometer-scale architecture in solution-processed nanomaterials to generate unique optical, electronic, magnetic, structural, and electrochemical properties. Her group specifically focuses on four main areas, including (1) self-assembling organic materials for application in solar energy harvesting, (2) optimizing nanoscale architecture for performance in electrochemical energy storage, (3) nanomagnetics and magnetoelectric composites, and (4) new ultra-hard materials.
