Some key papers include: Using Re-Os isotopes to determine the deposition age of petroleum source-rock formation (organic-rich shales) is a major research theme, both in terms of technical development and application.This method has been applied to better understand the origins of global Oceanic Anoxic Events (OAEs), the timing of shale deposition and correlation in Precambrian sedimentary basins and this rise of oxygen on Earth.Re-Os isotopes in natural hydrocarbons is the third major research theme of the laboratory, again approaching this new field from both a systematic evaluation and application perspective.

Development of Re-Os geochronology for crustal matrices has been ongoing since 1998 in the laboratory.

This work has resulted in major advancements in the direct isotopic dating of crustal sulfide minerals, petroleum source-rocks, and natural hydrocarbons, using Re-Os isotopes.
