He is recipient of a Sloan Foundation Fellowship, a Packard Fellowship, the Bok Prize, and the Trumpler Award from the Astronomical Society of the Pacific. With over 90 published papers, he leads theoretical modeling of the redshifted 21-cm signal from the Dark Ages. He wrote the definitive review article on using the 21-cm signal to study reionization. As a senior member of the DARE Science Modeling team, he compares models of the star formation and black hole accretion to the observed DARE spectrum.

Dayton Jones (Co-I) is a cm and meter wavelength radio astronomer. He has been PI of radio tracking of CASSINI. Dayton has conducted extensive research on the Space Interferometry Mission and Lunar telescope design studies at JPL. He co-leads the instrument calibration and data analysis in DARE project.

Justin Kasper (Co-I) is an Associate Professor at University of Michigan. His research interest include low frequency EM instruments in space. He is PI of Solar Probe Plus and SWEAP. He is interested in understanding the forces that lead to solar flares and the solar wind, a stream of particles heated to millions of degrees in the Sun's atmosphere, or corona. He is also Co-I of Solar Orbiter and RPW. Justin is also project scientist for LRO, CRaTER, WIND and DSCOVR. He leads the science enhancement option of DARE project in identifying solar and planetary radio transients.

Abraham Loeb (Co-I) is Professor of Astronomy and Director of the Institute for Theory and Computation at Harvard University. Previously, he was a member of the Institute for Advanced Study at Princeton. He received a Guggenheim Memorial Foundation Fellowship and Kennedy Prize from the Hebrew University. Loeb has published over 340 papers and pioneered theoretical studies of the cosmic 21-cm signal that we seek to detect with DARE. Loeb is a senior member of the Science Modeling team. He leads the effort to interpret the DARE spectrum based upon a suite of models of the physics in the Dark Ages.

Jordan Mirocha (Co-I) is a Postdoctoral Scholar at University of California Los Angeles. He is part of the Science Modeling Team. Dr. Mirocha will provide assistance with DARE’s signal extraction pipeline (PERSES), which he co-developed, and continue to maintain, and develop the ARES code, which will be used to constrain theoretical models of galaxy formation using DARE data.

Raul Monsalve (Co-I) is a Research Associate at the University of Colorado Boulder. His research interests include experimental cosmology and low frequency radio astronomy. As a member of the EDGES team, he has extensive experience with the design, implementation, and operation of ground-based global 21-cm experiments, as well as with their calibration and data analysis. Dr. Monsalve will contribute to DARE by producing the measurement model corresponding to the foregrounds and instrument, including their uncertainties.

David Rapetti (Co-I) is a NASA Program Senior Fellow at the University of Colorado Boulder and at AMES Research Center. Dr. Rapetti will develop the mission’s global 21-cm signal extraction pipeline based on a Bayesian framework and a Markov Chain Monte Carlo (MCMC) analysis, which self-consistently and simultaneously accounts for foreground and instrumental systematic uncertainties. He will also lead the use of Bayesian evidence calculations to further distinguish between the currently allowed models of the first luminous objects at end of the Dark Ages and beginning of the Cosmic Dawn as well as exotic physics impacting the 21-cm spectrum at this early, unexplored cosmic epoch.

Edward Wollack (Co-I) is a Research Astrophysicist at NASA Goddard Space Flight Center. He worked as Project Scientist and Instrument Integration Leader for the WMAP space cosmology mission. For DARE, he participates in the instrumental design as well as throughout the science investigation.

Michael Bicay (Collaborator) is Director of Science at NASA Ames Research Center (ARC). He was a NASA Headquarters Program Scientist for a variety of radio and infrared astronomy missions for six years. He was also on the science staff at JPL and a member of the Project Office for the Spitzer Space Telescope. He has extensive experience with radio and infrared observations of galaxies and galaxy clusters. Dr. Bicay’s primary role will be to ensure that DARE receives appropriate institutional support from NASA Ames, working in collaboration with the Center’s Director for Programs/ Projects.
