Professor Gill's research interests are focused on two distinct but interrelated areas: multidisciplinary education and sustainable product development. The first facet of her research relates to the difficulties inherent in generating and communicating design concepts in a multidisciplinary team setting. Design for sustainable product development is in effect, the specific area in which she has chosen to apply her research, since it is intrinsically multidisciplinary and demands close collaboration between design methodologies and engineering applications.
