Dr. Turrin’s research interests are in geochronologic studies of Earth-Solar System processes and events such as; biological evolution, adaptive radiations, extinctions and recoveries, climate change, catastrophes, and a better understanding of how Earth-Solar System has evolved. Moreover, temporal relations are often at the core of causality arguments in Earth-Solar System history. Hence, he actively works on improving the precision and accuracy of the K-Ar (40Ar/39Ar) chronometer, leading to a better understanding of both the dates and rates of these processes.
