Ionizing radiation pervades our environment and affects all life on earth. The absorption of this impinging energy produces profound chemical and biochemical transformations in the materials irradiated. Professor Carmichael's research provides a fundamental molecular-level understanding of these radiation effects in matter.
The work is performed in the Notre Dame Radiation Laboratory, the premier facility for radiation chemical research in the US, supported by the Chemical Sciences Division of Basic Energy Sciences at the US Department of Energy. The NDRL provides not only access to unique experimental tools but also outstanding research opportunities for focused interdisciplinary collaborations. Knowledge gained from this research provides the scientific basis for solving problems ranging from the chemical conversion of solar energy, through nuclear energy production, environmental waste management and remediation, to biomedical radiation therapy.
Specific topics currently under active investigation include:
Radiation damage in protein crystallography
Understanding and mitigating radiation damage during macromolecular crystallography at synchrotrons
Electron-driven processes in condensed phases
Excited species in water radiolysis; radical formation in irradiated organic liquids
Radiation effects in heterogeneous systems and at interfaces
Characterizing radiation chemistry at water - ceramic oxide interfaces
Spin coupling in biomolecular NMR
Probing conformational and chemical changes in carbohydrates
