John Ruhl (physicist)

Ruhl received a BS in physics from the University of Michigan in 1987 and a Ph.D. in physics from Princeton in 1993. While a graduate student at Princeton, Ruhl, along with several other graduate students, co-authored the text Princeton Problems in Physics.{{cite journal|last=Holstein|first=Barry R.|bibcode=1992AmJPh..60..477N|date=May 1992|doi=10.1119/1.16855|issue=5|journal=American Journal of Physics|pages=477–478|title=Review of Princeton Problems in Physics with Solutions|volume=60}} His doctoral dissertation, A search for anisotropy in the Cosmic Microwave Background Radiation, was supervised by Mark Dragovan.{{cite web|url=https://astrogen.aas.org/front/searchdetails.php?agnumber=11242|title=John Edward Ruhl|work=Astrogen|publisher=American Astronomical Society|access-date=2023-08-16}} See also Ruhl's dissertation at {{ProQuest|304101104}}.

Ruhl is an experimentalist in cosmology. He studies the cosmic microwave background radiation and has been principal or co-principal investigator on the Spider CMB,{{cite news|newspaper=The Antarctic Sun|url=https://antarcticsun.usap.gov/science/4142/|publisher=United States Antarctic Program|date=April 27, 2015|first=Peter|last=Rejcek|title=A sticky problem: SPIDER seeks clues to the enigma of how the universe first expanded|access-date=2023-08-16}} South Pole Telescope,{{cite news|newspaper=The Antarctic Sun|url=https://antarcticsun.usap.gov/pastIssues/2002-2003/2002_12_01.pdf|publisher=United States Antarctic Program|date=December 1, 2002|title=Looking for the dark side of the universe|first=Kristan|last=Hutchison|access-date=2023-08-16}} ACBAR{{cite web|url=https://www.nsf.gov/news/news_summ.jsp?cntn_id=106966|publisher=National Science Foundation|title=Scientists Use South Pole Telescope to Produce the Most Detailed Images of the Early Universe|date=December 13, 2002|access-date=2023-08-16}} and Boomerang experiments.{{cite web|url=https://www.nasa.gov/home/hqnews/2001/01-087.txt|publisher=NASA|date=April 29, 2001|first=Dolores|last=Beasley|title=New Boomerang Findings Reveal "Music" of the Early Universe|access-date=2023-08-16}}

Ruhl was named a Fellow of the American Physical Society (APS) in 2005, after a nomination from the APS Division of Astrophysics, "for his fundamental experimental contributions to the study of the cosmic microwave background radiation".{{cite web|url=https://www.aps.org/programs/honors/fellowships/archive-all.cfm?initial=&year=2005&unit_id=DAP&institution=|title=Fellows nominated in 2005 by the Division of Astrophysics|work=APS Fellows archive|publisher=American Physical Society|access-date=2023-08-16}} In 2016, Case gave him their John S.
