Upon completing his PhD, Bloom became a postdoctoral researcher at
Johns Hopkins University and the
University of Michigan before accepting an
assistant professor position at the
University of Nebraska–Lincoln (UNL). In 2004, Bloom collaborated with Aaron Dominguez to enlist David Swanson in encouraging
CERN to invest in upgrading the university's network. Their encouragement was successful and Bloom was subsequently chosen to lead all seven
Compact Muon Solenoid particle detector sites spaced around the 17-mile-long
Large Hadron Collider (LHC) supercollider ring, Tier2 sites in the United States. In this role, Bloom oversaw the Compact Muon Solenoid, one of the two largest experiments at the LHC. Two years later, Bloom worked alongside more than 2,000 other scientists and researchers on the
Higgs boson which was the recipient of a
Nobel Prize in Physics. In 2015, Bloom was appointed the software and computing manager for the United States Compact Muon Solenoid operations program. He gained new responsibilities in his role including overseeing an annual budget of $18 million. His real-life blog Quantum Diaries was recognized on the television show
The Big Bang Theory and served as a plot point for the episode. In the episode, he discusses the fictional study of main characters
Sheldon Cooper and
Leonard Hofstadter as an "admirable example of rare collaboration between a theorist and experimentalist" but warns them to disregard the rude comments. The following year, Bloom was elected a Fellow of the
American Physical Society for his "contribution to characterizing the top quark, the heaviest known subatomic particle, from data gathered at the Tevatron collider and Large Hadron Collider." He was also promoted to the rank of
full professor in Physics and Astronomy. During the
COVID-19 pandemic, Bloom was chosen to serve as a faculty associate to the chancellor for budget model implementation. In this new role, he was expected to advise on the development of the new incentive-based budget model and advise on effective planning, operations, and related governance. He was also named to the school's COVID-19 Budget Advisory Committee and executive committee. ==Personal life==
