Research Interests

Reactions and radiative processes of excited atoms and molecules; laser spectroscopy; high power lasers; clusters and nanoparticles.

Laser Spectroscopy and Nanoparticle Research

Our goal is to develop manufacturing techniques for nanocomposite and nano-heterogeneous materials and devices that combine the functional advantages obtained from the “size-tunable” properties of nanocomposite materials with the fabrication and direct-write advantages available from nanoparticles manufactured and delivered in aerosol form.
