Career Research Highlights

Selby has been involved in the development and application of the Re-Os isotope system since 1999. His research focuses on the systematic development and application of the Re-Os isotope system to economic geology (e.g., sulfide Re-Os geochronology), chronology of sedimentary and petroleum systems, paleoclimate, paleoceanography, macroalgae, and the anthropocene.
His research is conducted in the Source Rock and Sulfide Geochronology and Geochemistry Laboratory and Arthur Holmes Laboratory, which forms an integral part of the Durham Geochemistry Centre.
For excellence in contributions to applied and economic aspects of the science Selby has been awarded the William Smith Fund (2009) from The Geological Society of London. He is also a Fellow of the Geological Society of America. In 2014 he received an award for excellence in doctoral supervision.
