Research Interests

Our research focuses on the biomolecule-material (Bio-Material) interaction at interfaces and in biological systems. Most of my previous work addresses the simplest but most mysterious molecule in nature: water. Currently, I am interested in the interaction of biological systems with materials such as the DNA-carbon nanotube interaction. The biomolecule-material interaction also motivates my work in understanding melanin structure, biocompatible self-cleaning surfaces, hydrogen storage and artificial photosynthesis, as they use the same principles on the microscopic level. These systems are of great importance in solving today’s energy problems and curing human diseases such as melanoma and Parkinson’s disease. The contact between traditional materials and biomolecules, which is nanometer scale in nature, raises interests for both fundamental understanding and novel applications including biosensors, bio-implants, DNA diagnostics, and solar light harvest.

Three research
frontiers can be envisioned from studying phenomena at Bio-Material interfaces: 1) fundamental understanding of Bio-Material interactions, 2) applications to renewable energy research, and 3) theory development. These three areas are interconnected. Fundamental understanding of biomolecule-material interactions is of great significance to basic science as we enter the post-genome era, as well as to the growing desire to engineer gene expression, drug delivery, biosensors, and energy manipulation. By mimicking natural processes of energy management and engineering at Bio-Material interfaces, we can learn a great deal about how to solve today’s global energy challenge. This could be achieved by studying and understanding water splitting in biology for hydrogen generation, the anchoring of chlorophyll pigments, or the use of photosynthetic proteins with a semiconductor surface for light harvest. All these studies require theory development towards an accurate quantum mechanical description of the molecular structure, vibrations, and electronic excited states at the atomic level, which is the common theme underlying all our research.
