Excited State Dynamics in Organic Semiconductors |
In our group we study excited state dynamics in polyacene molecular crystals and low bandgap conjugated polymers designed for use in photovoltaic devices. For more information, please click on the link. |
Photoinduced Relaxation Processes in DNA Bases |
Nonlinear Optics |
Our group has constructed several specialized nonlinear optical devices to address specific scientific questions in a wide variety of materials. Laser pulses produced with these devices span ultraviolet to infrared wavelengths with durations ranging from 15fs to 1ps. For more information, please click on the link. |
Photosynthetic organisms must move photoexcitations efficiently in order to maximize the production of carbohydrate fuel. We investigate energy transport mechanisms in light harvesting proteins of cyanobacteria. For more information, please click on the link. |
Research |
Photoinduced relaxation processes in DNA bases are investigated using specialized femtosecond laser spectroscopies conducted in the mid-UV spectral range. We have recently demonstrated the feasibility of “photon echo” techniques that will hold many advantages for the study of biomolecules whose lowest energy electronic resonances are found in the mid-UV (e.g., DNA bases, amino acids).

Light Harvesting Mechanisms in Cyanobacteria |
Electronic Dynamics at Molecule-Semiconductor Interfaces |
Knowledge of electronic structure and transport mechanisms in dye-sensitized semiconductors is motivated by their ubiquity in photoelectrochemical cells. We use femtosecond laser spectroscopies to investigate the nature of electronic states in nanocrystalline semiconductor films sensitized with molecular adsorbates. |
