Giovanni Meloni

Associate Professor

Prior to joining the University of San Francisco, Dr. Meloni carried out post-doctoral research at the University of California, Berkeley and at Sandia National Laboratories. In his research, he employed state-of-the-art experimental and computational techniques, to study semiconductor clusters, van der Waals species, and hydrocarbon radicals. Dr. Meloni's interests range from high-temperature physical chemistry to spectroscopic characterization of reaction intermediates. More recently, his research group performs experiments at the Advanced Light Source of Lawrence Berkeley National Laboratory using a multiplex photoionization mass spectrometer to investigate biofuel molecules combustion and atmospheric reactions.
