My research interests are broadly in the field of green and environmental chemistry and designed to facilitate undergraduate participation.  Our group works with a class of non-volatile and non-flammable solvents termed ionic liquids (ILs). We are interested in both the applications of ILs in various processes and environmental remediation as well as fundamental properties of the solvents such as toxicity, role of water in modifying properties etc. Through a recent Aisiku Interdisciplinary STEM Research Team Initiative grant I have been working with an interdisciplinary group to assess the effects of urbanization on the water quality of the Tatnuck Brook watershed. Some of my research also involves development of green chemistry education materials for use in the undergraduate curriculum.
