Research in my group is directed towards understanding the nature of elementary processes in biological systems. We relate dynamics and structures to functions at the most fundamental level with state-of-the-art femtosecond lasers and molecular biology techniques. The laboratory ultimately will have the capability of time resolution from femtosecond to millisecond (second); biological systems can be prepared and studied at the single molecule level. We are currently focusing on studies of bimolecular recognition and ultrafast protein/enzyme dynamics of several important biological systems.
