The Tony Davies Column is edited by two people, both called Tony Davies! They are responsible for columns in alternate issues. A.M.C. (Tony) Davies (left) concentrates on the data processing and chemometrics associated with spectroscopy. A.N. (Tony) Davies (right) columns are concerned with data handling issues. This picture was taken on the Spectroscopy Europe booth at Pittcon 2001. |
