The continuing long term goal of my research is to develop to the utmost, the capabilities of Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) for the analysis of geological samples. The emphasis is on solid materials from the geosphere, but samples from the hydrosphere, atmosphere, and biosphere, which reflect their association with the solid earth and thus contain trace elements which reflect the environment, are included. The integration of ICP-MS with other important geoanalytical methods including especially thermal ionization-mass spectrometry (TI-MS) and X-ray fluorescence (XRF) will continue with the goal of developing cost effective, precise, and accurate analyses. That "no method is a panacea" is a guiding principle of my work. My long term goal is to develop methods to determine all of the naturally occurring elements of the periodic table at the concentrations that they are found in real samples. ICP-MS along with XRF procedures currently in place at Memorial University approach this goal, but there are analytes for which additional work is required.

我继续研究的长期目标是最大限度地发展电感耦合等离子体质谱(ICP-MS)分析地质样品的能力。重点是来自地圈的固体物质，但也包括来自水圈、大气和生物圈的样品，这些样品反映了它们与固体地球的联系，因此含有反映环境的微量元素。电感耦合等离子体质谱(ICP-MS)与其他重要的地质分析方法，特别是热电离-质谱仪(TI-MS)和X射线荧光(XRF)的结合，将继续以开发具有成本效益的、精确和准确的分析为目标。没有一种方法是灵丹妙药，这是我工作的指导原则。我的长期目标是开发方法来确定元素周期表中所有自然出现的元素的浓度，这些元素在实际样品中发现的浓度。电感耦合等离子体质谱(ICPMS)和目前在纪念大学实施的XRF程序可以实现这一目标，但也有需要进行额外工作的分析物。
