My research interests are in the area of non-thermal plasmas, in particular those used for materials modification and production. I have experience in probing plasmas through a variety of spectroscopic measurements, and correlating these with properties of the materials that have been produced by these plasmas. Current research is directed towards production of materials for water treatment.
