Time resolved imaging and spectroscopy of photosynthetic systems |
Scientific Interests
Ultrafast spatial imaging of energy transfer processes in natural and artificial photosynthetic architectures ― Combining near-field scanning microscopy and ultrafast spectroscopy to achieve simultaneous nanometer spatial resolution and subpicosecond temporal resolution. Ultrafast imaging of energy flow in photosynthetic architectures will provide answers to important questions concerning photosynthetic light harvesting, transfer, and capture.
Recent Accomplishments | Top |
High-resolution function mapping of 3D photosynthetic crystals ― The fundamental question in biology is to correlate structure with function. Utilizing femtosecond optical spectroscopy, we studied photosynthetic function directly in single reaction center crystals. This provided opportunities to make direct, quantitative correlation between photosynthetic function and known reaction center structure obtained in crystals.
Ultrafast dynamics of semiconducting nanomaterials ― Ultrafast nonlinear optical spectroscopy was utilized to explore the optical and electronic properties of single-walled carbon nanotubes and semiconducting quantum dots. This project provided important insights into the excited state dynamics and excitonic properties of these important materials.
