Biophysics & Biomedical Physics

This group, led by Dr. Susanne Ullrich, uses modern time-resolved pump-probe spectroscopies to study the function and dynamics of photoexcited biomolecules. Experimental facilities include a high energy femtosecond laser system and photoelectron photoion coincidence spectrometer.
