Research
In 2009, ScienceWatch wrote that Bloom's gamma-ray bursts "work ranks at No. 10 by total cites, based on 85 papers cited a total of 3,639 times. Five of these papers are on the lists of the 20 most-cited papers over the past decade and over the past two years."{{Cite web | title = Gamma-ray Bursts, Special Topics Interview | publisher=Thomson Reuters ScienceWatch | date = August 2009 | url=http://sciencewatch.com/ana/st/gamma/09augGamBloom/ | accessdate = March 3, 2019 }} He has published over 300 refereed articles{{Cite web | title=Refereed articles of Joshua Bloom | url=http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?db_key=AST&sim_query=YES&ned_query=YES&aut_xct=YES&aut_logic=OR&obj_logic=OR&author=Bloom%2C+J.S.%0D%0ABloom%2C+J.%0D%0ABloom%2C+J.+S.%0D%0ABloom%2C+Joshua%0D%0ABloom%2C+Joshua+Simon%0D%0ABloom%2C+Josh%0D%0ABloom%2C+Joshua+S.&object=&start_mon=&start_year=&end_mon=&end_year=&ttl_logic=OR&title=&txt_logic=OR&text=&nr_to_return=100&start_nr=1&jou_pick=NO&ref_stems=&data_and=ALL&group_and=ALL&start_entry_day=&start_entry_mon=&start_entry_year=&end_entry_day=&end_entry_mon=&end_entry_year=&min_score=&sort=SCORE&data_type=SHORT&aut_syn=YES&ttl_syn=YES&txt_syn=YES&aut_wt=1.0&obj_wt=1.0&ttl_wt=0.3&txt_wt=3.0&aut_wgt=YES&obj_wgt=YES&ttl_wgt=YES&txt_wgt=YES&ttl_sco=YES&txt_sco=YES&version=1 | accessdate = January 4, 2011 }} and was principal investigator of the Peters Automated Infrared Telescope (PAIRITEL) | title = PAIRITEL, Robotic Telescope for the 21st century | url = http://pairitel.org/ | url-status = dead | accessdate = January 4, 2011 | archive-url = https://web.archive.org/web/20110105115139/http://pairitel.org/ | archive-date = January 5, 2011 | df = mdy-all at the Fred Lawrence Whipple Observatory in Arizona.
