Prof. Ken Ghiggino

Chief Investigator

Ultrafast and Microspectroscopy Laboratories

Ghiggino's group study excitonic processes in various systems including luminescent concentrators, non-coherent light upconversion and light harvesting systems for photovoltaic and artificial photosynthesis applications. He has access to sophisticated spectroscopic equipment including ultrafast transient absorption and fluorescence instrumentation to follow these processes.
