Christopher Hamann

Tasks
  • Research Assistant, PhD Student (DFG-funded Research Unit MEMIN)
  • Assistant, Dachverband Geowissenschaften (DVGeo) at Museum für Naturkunde
Research interests

Primary research interests:

  • Formation, petrology, and geochemistry of impact melts formed in terrestrial impact structures (Wabar, Meteor Crater, Kamil, Tenoumer) and in experiments (hypervelocity impact experiments, laser-irradiation experiments)
  • Chemical interaction between projectile and target during impact
  • Development and application of laser irradiation for planetary sciences/impact studies

Research projects:

  • Projectile–target interaction, melting, and vaporization in hypervelocity experiments and natural impactites (DFG-funded Research Unit MEMIN)
