Catalyst Testbed

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new

Micro- and nano-optomechanical systems

Ongoing
Our primary current research direction involves the use of fabricated devices with sub-wavelength periodicity (photonic crystals) as optomechanical elements. Such structures enable a rich variety of devices, including mirrors, polarizers, and filters, in a configuration that couples naturally to

Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have
