About the speaker:

David Cook is a Dozent & Oberassistent (Lecturer & Senior Scientist) at the Institute for Geochemistry and Petrology - ETH Zürich, Zürich, Switzerland. David completed a PhD in geology at the University of Chicago, and has 19 years of experience conducting quantitative research in geochemistry at several top-ranked universities, both in the United States and Europe. He focuses on method development, clean-room protocols, working with precious samples, and mass spectrometry. He has 6 years teaching experience, as well as training and supervision of students and junior colleagues.

Isotopes provide a powerful tool to trace events in the early solar system. This includes determining the timeline of these events, as well as identifying the possible stellar sources that contributed to the material from which the planets formed. I will present a case study using tungsten isotopes to show how we can investigate the level of isotopic heterogeneity within the solar system and how radiogenic decay and galactic cosmic rays can affect the isotopic record in meteorites.
