The Laboratory for Particle Physics and Cosmology (LPPC) at Harvard University conducts cutting edge research in experimental particle physics and observational cosmology, and provides education for graduate and undergraduate students.

Palfrey House


The LPPC is led by six faculty members from Harvard Physics and Astronomy Departments: Profs. Carlos ArgüellesMelissa Franklin, Roxanne Guenette, John HuthMasahiro Morii, and Chris Stubbs.

Astroparticle Physics Frontier

The Astroparticle Physics Frontier Group is led by Carlos Argüelles, a neutrino physicist. His work explores properties of neutrinos using data from the IceCube Neutrino Observatory. IceCube data provides a unique window on the highest energy neutrinos ever observed. It is an ideal place to search for new Beyond Standard Model effects.

Energy Frontier

The Energy Frontier Group, led by Profs. Franklin, Huth, and Morii, studies the highest-energy proton-proton collisions with the ATLAS Experiment at the Large Hadron Collider (LHC). We measure the properties of the Higgs boson, and searches for new physics beyond the Standard Model.

Intensity Frontier

The Intensity Frontier Group, led by Prof. Guenette, studies neutrino oscillation, searches for sterile neutrinos, and measures neutrino interaction with the MicroBooNE, SBND and DUNE experiments.

Cosmic Frontier

The Cosmic Frontier Group, led by Prof. Stubbs, is primarily working on the development of the Large Synoptic Survey Telescope (LSST) as a tool for studying the accelerating expansion of the Universe. Our group plays a central role in the calibration system, in optimizing implementation of the LSST survey strategy, and in commissioning and exploitation of the full LSST system. Working in partnership with DOE laboratories (SLAC and BNL), we are also engaged in the construction of the 3.5 Gpixel LSST camera system. 

LPPC Buildings

LPPC is spread across buildings in the Northwest Campus. Our main office building is Palfrey House, originally built by John Palfrey. To find Palfrey on the Harvard campus, view this Harvard Map.
