Exploring the nature of neutrinos and their deep connection between particle physics, quantum mechanics and cosmology.

The Formaggio neutrino group is a member of the Neutrino and Dark Matter Group at MIT (NuDM). The NuDM consortium of three faculty members (Conrad, Formaggio, and Winslow) are devoted to understanding one of the most elusive known particles in the Universe: the neutrino.  The Formaggio group focuses on measuring some of the most fundamental properties of neutrinos:  their mass and how they interact with matter.  The group also develops novel sensing technologies in order to probe these fundamental properties.

Neutrinos remain one of the least understood members in the Standard
Model particle zoo. 

Joseph Formaggio received his B. S. degree from Yale University in physics in 1996, and his Ph.D. in physics from Columbia University. In 2001, he joined the Sudbury Neutrino Observatory as a postdoctoral fellow at the University of Washington, working on solving the so-called “solar neutrino problem.”  He joined the MIT Physics Department in 2005, where he continues to work on experimental neutrino physics.

The Formaggio group is active in a number of different experiments, each dedicated to better understand the elusive properties of neutrinos.


 Based in Germany, KATRIN makes use of the well-developed technology of magnetic adiabatic collimation to study the endpoint energy of tritium beta decay.

Project 8

Project 8 is a next-generation tritium beta decay experiment that makes use of frequency to measure electron energies, using the technique of Cyclotron Radiation Emission Spectroscopy (CRES). LEARN MORE
