Radiation damage quantification in elemental copper using Wigner energy storage
Radiation damage in materials can cause critical components in fission and fusion reactors to fail with potentially catastrophic consequences. Radiation damage quantification is essential for understanding, predicting, and preventing such failures. The current unit of radiation damage, …

A novel DNA damage quantification platform enables high throughput screening for genes that impact DNA double strand breaks
… However, our genomes are constantly being damaged by reactive molecules generated from cellular metabolic processes or introduced from the environment. The resulting DNA damage can alter the information encoded in DNA, and can interfere with the accurate transmission of genetic information …

The forensic reconstruction of road traffic accidents
… project aims to approach the issues of collision damage quantification and accident scene reconstruction in a critical manner. A series of accident scenarios that demonstrate modern-day vehicle collisions will be presented. The collision damage will be studied with regard to the scene, environment …
