There are three research themes:
i. Biomaterials. Biomaterials encompass any material, created either by self-assembly or via elaborate multi-step synthetic routes, that interacts with living systems. The key concepts of biocompatibility, degradation, biomimetics, and structure/function relationships guide the development and applications of new biomaterials. Research in the area of biomaterials draws on integration of concepts related to evaluation of biocompatibility and toxicology, mechanical and structural properties, pathobiology, and ultimately biofunction.
ii. Energy materials. Our interest in the energy arena bridges both the implementation of more energy-efficient processes and the development of renewable energy sources and better energy storage devices. This includes harnessing solar energy, and development of photovoltaics, biofuels, and batteries. Specific research groups are focusing on discovery of more efficient photovoltaic materials; development of catalytic methods for hydrogen production, storage and delivery; and development of new devices for solar energy capture and conversion.
iii. Materials Characterization. Several of the participating research groups are focused on the development of innovative methodologies and instrumentation for characterization of materials. Analysis of materials offers significant challenges on many levels, from the heterogeneity of nanoscale composites to the complexity of bio-inspired films. Spectroscopic and microscopic strategies are at the forefront of this area, and research projects will encompass development of new analytical/physical methods, application of those methods for characterization of biomaterials and energy materials, and assessment of performance metrics.
