221:. Building on his work with SDSS, Frieman later co-founded and served as director of the Dark Energy Survey (DES) with the goal of collecting data that would help physicists determine which theoretical models explaining the increasing rate of the expansion of the universe might be correct. The Dark Energy Survey began its observations in 2013 and concluded them in 2019. These observations produced a large amount of data, which the DES collaboration is still analyzing. In 2004, Frieman was elected a fellow of the

Science Distinguished Scientists Fellow "for pioneering advances in the science of dark energy and cosmic acceleration, including leading the Sloan Digital Sky Survey-II Supernova Survey, co-founding the Dark Energy Survey and service as its Director." Frieman was also
