Use of infrared (2D IR) spectroscopy, protein semisynthesis and site-specific labeling techniques to:

1. Examine the structures and physical properties of β-sheet rich biological materials and use this information in biomaterials design.

2. Investigate the functional roles of fast (fs-ps) vibrational dynamics in the functions of photoactive proteins, electron transfer proteins and enzymes.
