We are an experimental astroparticle physics research group at the Georgia Institute of Technology. We specialize in the observation of very-high-energy (VHE) gamma-rays with imaging atmosphere Cherenkov telescopes (IACT) and ultra-high energy neutrinos.

Our main research is about understanding the acceleration of charged particles (cosmic rays) in pulsars and using gamma-rays as probes of Lorentz invariance violation but we also deviate and do other interesting research in the VHE gamma-ray band. We are members of the VERITAS Cherenkov telescope array and participate in the development and construction of the next generation VHE instrument the Cherenkov Telescope Array CTA.

More recently we are also interested in ultra-high energy neutrinos and how to detect them with detectors on the ground (Trinity) and in space (POEMMA). Both experiments are in their design phase. Our group is leading the effort on Trinity and has funding from the National Science Foundation to build a 1.5 square meter Demonstrator telescope. The telescope will be deployed on Frisco Peak in Utah in 2022.

Our group has extensive know-how in the characterization of semiconductor photon detectors and classical photomultipliers. Photon detectors are a key component in all the experiments we participate in. In-depth knowledge of how these devices work is necessary to fully exploit the scientific potential of astroparticle experiments that use them. We have a variety of test equipment and procedures to evaluate silicon photomultipliers and classical photomultipliers. Most of the setups are described in this paper. We welcome external groups to use our setups. In case you are interested in using them get in touch with us.

In an ongoing effort, we develop III-V compound semiconductor photon detectors in collaboration with Prof. R. Dupuis and Prof. S. Shen both here at Georgia Tech.
