The research in my group is currently focused on the analysis and environmental fate on contaminants of emerging concern. Contaminants of emerging concern include both truly new contaminants for which little published scientific data are available (e.g., many pharmaceutical products, perfluorinated surfactants, plasticizers), along with legacy contaminants which are regaining “popularity” because of newly discovered issues and potential effects and problems (e.g., Pb and Mn in drinking water, As in rice). In most of these situations, the research work in my group is divided into the development of the appropriate analytical chemistry/sample preparation methods, environmental applications to real-world samples, and the studies of the fate and potential effects of those compounds in the environment. The work aims to be multidisciplinary to account for an excellent analytical chemistry development, combined with the ruggedness to cope real world sample and the risk analysis required to properly interpret the meaning of such results (analytical tools have attained such performances that detecting the presence of a contaminant is not enough to conclude about the potential risks that it may represent). We then follow with environmental fate of such contaminants across a variety of media (soil, water, sediments, air).

我的小组目前的研究重点是对新出现的污染物的分析和环境归宿。新出现的令人担忧的污染物包括几乎没有发表的科学数据的真正的新污染物（例如，许多药物产品、全氟化表面活性剂、增塑剂），沿着由于新发现的问题和潜在的影响和问题而重新“流行”的遗留污染物（例如，饮用水中的铅和锰，大米中的铅）。在大多数情况下，我们小组的研究工作分为开发适当的分析化学/样品制备方法，环境应用于实际样品，以及研究这些化合物在环境中的命运和潜在影响。这项工作旨在是多学科的，以说明一个优秀的分析化学的发展，结合耐用性，以科普真实的世界样品和风险分析所需的正确解释这些结果的含义（分析工具已经达到这样的性能，检测污染物的存在是不够的，它可能代表的潜在风险的结论）。然后，我们跟踪这些污染物在各种介质（土壤，水，沉积物，空气）中的环境命运。
