THE EXPERIMENT FOR CRYOGENIC LARGE-APERTURE INTENSITY MAPPING (EXCLAIM) IS A HIGH ALTITUDE BALLOON SPECTROMETER DESIGNED TO DEEPEN OUR UNDERSTANDING OF STAR FORMATION IN A COSMOLOGICAL CONTEXT. IT WILL MAP THE SUB-MM EMISSION OF REDSHIFTED CO AND CII LINES IN WINDOWS COMPRISING 0<Z<3.5. THESE LINES TRACE THE PRECURSORS OF STAR FORMATION BUT HAVE ONLY PRELIMINARY CHARACTERIZATION BEYOND THE NEARBY UNIVERSE WHICH IS OFTEN LIMITED TO THE BRIGHTEST OBJECTS OR GALAXIES SELECTED IN OTHER SURVEYS. RATHER THAN DETECT INDIVIDUAL GALAXIES EXCLAIM WILL MEASURE THE STATISTICS OF BRIGHTNESS FLUCTUATIONS OF REDSHIFTED CUMULATIVE LINE EMISSION. THIS APPROACH IS KNOWN AS INTENSITY MAPPING AND THE ENDURING QUESTS DARING VISIONS ROADMAP ESTABLISHES IT AS A PRIORITY IN THE VISIONARY ERA. EXCLAIM IS A PATHFINDER TO FUTURE MISSIONS WHICH USE INTENSITY MAPPING TO PROBE EARLY STAR FORMATION AND REIONIZATION. A BLIND COMPLETE CENSUS OF REDSHIFTED CO AND CII ADDRESSES NEW WORLDS NEW HORIZONS DECADAL SURVEY PRIORITIES TO UNDERSTAND BARYONS IN GALAXIES AND IN THE CONTEXT OF THEIR DARK MATTER HALOS. DR. BOLATTO WILL HELP ANALYZE AND INTERPRET THE RESULTS OF EXCLAIM IN THE CONTEXT OF WHAT IS KNOWN ABOUT THE PHYSICS OF CO AND [CII] EMISSION IN GALAXIES. UPON IDENTIFICATION OF A STUDENT INTERESTED IN PARTICIPATING IN THE INSTRUMENTATION AND DATA ANALYSIS I WILL ADVISE HIM/HER AND PREPARE AN ALTERNATIVE PROJECT IN CASE THE INSTRUMENT IS DELAYED OR EXPERIENCES TECHNICAL DIFFICULTIES.
