Philip Lubin is a professor of Physics at UC Santa Barbara whose primary research has been
focused on studies of the early universe in the millimeter wavelengths bands as well as
applications of directed energy for planetary defense and relativistic propulsion. His group has
designed, developed and fielded more than two dozen ground based and balloon borne
missions and helped develop two major cosmology satellites. Among other accomplishments
his group first detected the horizon scale fluctuations in the Cosmic Microwave Background
from both their South Pole and balloon borne systems twenty years ago and their latest results,
along with an international teams of ESA and NASA researchers, are from the Planck
cosmology mission which have mapped in exquisite detail the structures of the early universe.
He is a co-I on the Planck mission. His group has worked on applications of directed energy
systems for both small scale single launcher solutions as well as large standoff systems for
planetary defense and on applications to allow small interstellar probes to achieve relativistic
speeds for the first interstellar missions. He is co-recipient of the 2006 Gruber Prize in
Cosmology along with the COBE science team for their groundbreaking work in cosmology as
well as the 2018 Gruber Prize in Cosmology along with the Planck science team for their
determination of fundamental cosmological parameter. He has published more than 450 papers.
