Stephen Mojzsis
Stephen Mojzsis in 2019

Stephen James Mojzsis (born 21 June 1965) is an American geologist, solid state physicist and physical inorganic chemist[1]. His research spans a broad range of disciplines, but is primarily directed towards topics of planetary chemistry[2]. Mojzsis is known for his groundbreaking research on the origins of life[3], the first oceans[4], earliest life[5] and primordial crust on Earth[6], as well as history and tempo of late accretion[7] to the planets. He also investigates the long-term changes to biogeochemical cycles over geologic time. He is at the forefront of the development of the emerging fields of Geoastronomy and Biogeodynamics. At present, he is Research Professor at the Bavarian Geoinstitute for Experimental Geochemistry and Geophysics (BGI) of the University of Bayreuth in Germany. Mojzsis is also Honorary Professor at ELTE and also Senior Research Advisor at the HUN-REN Research Centre for Astronomy and Earth Sciences, both in Budapest, Hungary. For most of his career (2000-2021) he was at the University of Colorado in Boulder, where he achieved the rank of Full Professor of Geological Sciences.

Geoastronomy

In 2024, it was announced that Mojzsis and his fellow Principal Investigators Kevin Heng (LMU-Munich, Germany) and Fabrice Gaillard (CNRS/ISTO-Orleans, France) were awarded a European Research Council (ERC) Synergy grant to study the chemical foundations of rocky planets around Sun-like stars. They have framed this work (i.e. the fusion of geology and astronomy) as the start of a new field of science that is termed Geoastronomy.[8]

Early Life and Education

Stephen Mojzsis was born in Bronx, New York, on 21 June 1965 to immigrant parents. His mother Margaret Ellen Mojzsis (née McKenna) emigrated from Monaghan, Ireland. István Mojzsis, his father, was born in a small village near Jászberény, Hungary and fled the country as a result of the 1956 Hungarian Uprising. Stephen holds citizenships in the USA and Ireland. He has one sister, Katherine Anne Mojzsis, who is an accomplished artist. The family moved to Parsippany, New Jersey when he was 5 years old. He attended Parsippany Hills High School and graduated in 1983.

Stephen Mojzsis completed his undergraduate studies with a BA in Geology at Boston University in 1988 under the tutelage of Lynn Margulis and Paul Strother, where he was introduced by them to the concept of "Planetary Biology". Following some time spent in Hungary where he witnessed the political and cultural changes associated with the fall of the Berlin Wall and the collapse of Soviet-style autocracies in Central and Eastern Europe, he returned to Boston University to complete his MA in 1992 with Farouk El-Baz on desert geomorphology. In 1997, he earned his Ph.D. in Earth Sciences from the University of California at San Diego at the Scripps Institution of Oceanography under the direction of Gustaf Arrhenius. His doctoral advisor was both the grandson of the Nobel laureate Svante Arrhenius, and son-in-law of another Nobel laureate, George de Hevesy.

The focus of Mojzsis' Ph.D. work was on the earliest record of life locked in pre-3.83 Gyr-old paragneisses from the Itsaq Gneiss Complex in southern West Greenland.[9] While a doctoral student in the 1990s, Mojzsis was educated by and closely interacted with many prominent scientists in the origin of life field including Stanley Miller, Leslie Orgel, Albert Eschenmoser and Gerald Joyce. The late Carl Sagan was an enormous influence on the course of his scientific life, and they met in person on several occasions. Mojzsis' doctoral thesis work on the earliest evidence for life contained in the Akilia rocks from West Greenland was cited in one of the last of Sagan's publications.[10]

Subsequently, he moved to the University of California at Los Angeles to work with T. Mark Harrison at the then newly-established Keck-NSF National Ion Microprobe Facility. It was there, that Mojzsis and Harrison discovered that Hadean zircons as old as 4.38 billion years record oxygen isotopic evidence for liquid water and dynamic crustal processes already at the dawn of our planet's history.[11]

In 2000, Stephen Mojzsis accepted a professorship at the University of Colorado at Boulder, in the Department of Geological Sciences. He rose to the rank of Full Professor in 2014. In 2021, he moved to the HUN-REN Research Centre for Astronomy and Earth Sciences in Budapest, Hungary.

Career and Research

Mojzsis' research primarily concerns determination of the chemical foundations of planets[12]. One particular focus of his has been on trying to understand the planetary conditions necessary a world to be suitable for life to take hold. His work has been instrumental in identifying the Hadean Eon as the most likely time in which the biosphere on Earth emerged, deepening our scientific understanding of abiogenesis[13]. Over his career, Mojzsis has published extensively in peer-reviewed journals such as Nature, Science, Proceedings of the National Academy of Sciences (USA), Icarus, Earth and Planetary Science Letters, the Astrophysical Journal and Geochimica et Cosmochimica Acta.
