Mass Spectrometry (MS) is one of the key analytical methods used to identify and characterize small quantities of biological molecules embedded in complex matrices.  Although MS has found widespread use, technical improvements in its instrumentation are needed to extend its application to the grand challenges that face the environmental, chemical and biomedical sciences. In this talk we present our progress towards the use of MS for diagnosing ovarian cancer and heart disease, imaging tissue samples, and a variety of other applications that benefit from the high information content provided by modern mass spectrometric experiments. We also describe more fundamental work involving finite element simulations of ion transport processes at the atmospheric pressure interface of the mass spectrometer, and experiments with "thermometer molecules" to measure the degree of ion activation during the ion generation.
