Overview

What is he best known for?

The fields of study he is best known for:

  • Organic chemistry
  • Oxygen
  • Hydrogen

His primary scientific interests are in Meteorite, Astrobiology, Chondrite, Paleontology and Carbon. His research integrates issues of Hydrous pyrolysis and Pyrolysis, Organic chemistry in his study of Meteorite. He has included themes like Geochemistry, Payload and Isotopes of carbon in his Astrobiology study.

Chondrite is closely attributed to Organic matter in his study. His Organic matter research is multidisciplinary, incorporating perspectives in Mars Exploration Program, Martian surface, Meridiani Planum, Life on Mars and Regolith. His work carried out in the field of Carbon brings together such families of science as Abundance, Relative species abundance, Isotopes of nitrogen and Mineralogy.

His most cited work include:

  • Organic compounds in carbonaceous meteorites (428 citations)
  • Lunar and Planetary Science Conference (293 citations)
  • Extraterrestrial nucleobases in the Murchison meteorite (224 citations)

What are the main themes of his work throughout his whole career to date?

His scientific interests lie mostly in Astrobiology, Meteorite, Organic matter, Mars Exploration Program and Chondrite. Astrobiology and Habitability are frequently intertwined in his study. His Meteorite research integrates issues from Carbon, Organic chemistry and Abiogenesis.

His Organic matter research is multidisciplinary, relying on both Environmental chemistry, Pyrolysis and Mineralogy. His work on Exploration of Mars, Martian, Mars sample return and Martian soil as part of general Mars Exploration Program research is frequently linked to Sample, thereby connecting diverse disciplines of science. His primary area of study in Chondrite is in the field of Carbonaceous chondrite.

He most often published in these fields:

  • Astrobiology (37.05%)
  • Meteorite (22.95%)
  • Organic matter (22.30%)

What were the highlights of his more recent work (between 2016-2021)?

  • Astrobiology (37.05%)
  • Mars Exploration Program (20.33%)
  • Martian (8.20%)

In recent papers he was focusing on the following fields of study:

Mark A. Sephton mainly focuses on Astrobiology, Mars Exploration Program, Martian, Organic matter and Mars sample return. His study on Solar System, Life on Mars and Extraterrestrial life is often connected to Icy moon as part of broader study in Astrobiology. His Mars Exploration Program study combines topics in areas such as Biosignature and Hydrous pyrolysis.

His Organic matter research is multidisciplinary, incorporating elements of Carbonaceous chondrite, Ferrihydrite, Environmental chemistry, Hematite and Kerogen. His study looks at the relationship between Carbonaceous chondrite and fields such as Pyrene, as well as how they intersect with chemical problems. Mark A. Sephton combines subjects such as Murchison meteorite and Physical chemistry with his study of Organic chemistry.

Between 2016 and 2021, his most popular works were:

  • Transitory microbial habitat in the hyperarid Atacama Desert (83 citations)
  • A new thermal extraction protocol to evaluate liquid rich unconventional oil in place and in-situ fluid chemistry (33 citations)
  • The potential science and engineering value of samples delivered to Earth by Mars sample return : International MSR Objectives and Samples Team (iMOST) (18 citations)

In his most recent research, the most cited papers focused on:

  • Organic chemistry
  • Oxygen
  • Hydrogen

Mark A. Sephton focuses on Mars Exploration Program, Organic matter, Astrobiology, Exploration of Mars and Icy moon. In his research, Jarosite and Geologic Sediments is intimately related to Hematite, which falls under the overarching field of Mars Exploration Program. His Organic matter research is multidisciplinary, incorporating perspectives in Environmental chemistry, Carbonaceous chondrite, Pyrene and Kerogen.

His Kerogen research includes themes of Chromatography, Chondrite, Aromatic amino acids and Anoxic waters. The concepts of his Astrobiology study are interwoven with issues in Hydrous pyrolysis and Habitability. His study in Hydrous pyrolysis is interdisciplinary in nature, drawing from both Sedimentary rock, Organic geochemistry, Diagenesis and Clay minerals.
