He has contributed to the methodologies of field archaeology and landscape survey, particularly geophysics and the use of computers when recording and processing archaeological data.
It focuses on geology, geophysics (including seismology and volcanology), and nuclear science (particularly ion-beam technologies, isotope science and carbon dating).
This analysis is particularly well-suited for nontransparent media such as sand, gravel, quartz, or other granular materials that are common in geophysics.
