Education
Born in New England, he first studied stromatolites as a graduate student under famed paleobotanist Elso Sterrenberg Barghoorn at Harvard University.

He is best known for his work related to the Precambrian. In 2013, he was inducted as a fellow of the Geological Society of America. In 1979, he became a faculty member at the University of California, Santa Barbara, where he was a contemporary of Preston Cloud.
Stromatolites
Awramik is known for his long standing expertise on stromatolites.
His 1971 discovery of a link between a loss in stromatolitic diversity and the appearance of the first metazoans was published in Science. In 1974, he and Lynn Margulis gave an often-used definition of "stromatolite".
Origin of life
In 1983, he discovered what was then considered to be the oldest evidence of life on earth, located in Western Australia. His and others" work provided credence to the notion that life was likely as old as 3.5 Georgia.
Recent research
Awramik remains a faculty member at UCSB, where he continues to teach.
He continues to study stromatolites. Recently, he has begun studying Neoproterozoic deposits in eastern California. In 2003, he, Frank Corsetti and David Pierce published evidence in the Proceedings of the National Academy of Sciences of fossilized microbiota in Cryogenian rocks, a revelation which has cast doubt on the notion of the near elimination of life during potential equatorial glaciation during that period (commonly referred to as Snowball Earth).
