Clelia has 27 years of academic and professional experience in a wide range of both environmental and water resources engineering applications in surface water systems (SWS) (i.e. rivers, lakes, reservoirs, wetlands, estuaries and coastal marine waters) gained through her previous and current academic positions in Argentina, Australia and the United States. Her main research is focused on improving the scientific understanding of transport and mixing processes in SWS and the interplay between these processes and the biogeochemistry of the environment using high-level process fieldwork and data analysis, numerical modeling and mathematical scaling. This emphasis is motivated by her desire to develop sustainable engineering practices for the ecological outcome and the assimilative capacity of SWS. She has participated in and successfully directed and co-directed 30 major fieldwork projects, 20 within Australia and 10 around the world (Europe, Middle East, Southeast Asia, and The Americas) supported by competitive research grant schemes and partnerships with industry. She is currently contributing to the development of a fully 3D coupled physical and biogeochemical model of Lake Champlain as part of the Vermont EPSCoR Basin Resilience to Extreme Events (BREE) project.
