Mass spectrometry, real-time tissue analysis, chemical detection, analytical chemistry. Dr. Graham Cooks and his team have constructed miniature ion trap mass spectrometers. These may be applied to problems of trace chemical agent and explosives detection. Dr. Cooks is a past President of the American Society for Mass Spectrometry. His work is highly cited (one of the 100 most-cited chemists) and he has trained 95 Ph.D. students in analytical chemistry.
