WATERSHED HYDROLOGY RESEARCH

My research focuses on the soil and water resources at various scales within watersheds that contribute food, energy, water, and societal needs. Along with collaborators from a variety of disciplines, I am interested in soil surface dynamics, surface water quality degradation, and socio-hydrological development. I have a special interest in pursuing scholarship with a socio-hydrological perspective that benefits the local community, nation, and the world, including marginalized and underserved communities.

PREVIOUS AND ONGOING RESEARCH COLLABORATIONS

I have previously been involved in several projects at Washington State University in Professor Jan Boll's Laboratory. Research in Professor Boll's lab focuses on many scales and themes in hydrology from modeling catchment hydrology in the Palouse Region of Eastern Washington and Northern Idaho to characterizing stable isotopes in Costa Rica. 

The Soil and Water Lab of the Department of Biological and Environmental Engineering, Cornell University is an integrated, collaborative group of researchers with whom I conducted research in Ethiopia, Colombia, and Ithaca, NY under supervision of Professor Tammo Steenhuis. These projects entailed field research campaigns, soil sampling, hydrological modeling, and erosion risk mapping in the Amhara Region of Ethiopia with Bahir Dar University and Valle Del Cauca in Colombia with the International Center for Tropical Agriculture (CIAT)

Cielo is an imaginative engineer focused on combining her passion for environmental justice with systems thinking to support interdisciplinary research. She uses hydrodynamic modeling, spatial analysis, and risk assessment tools to study how the socioeconomic landscape impacts exposure and adaptation to climate hazards. The research she conducts concentrates on examining the past and potential impacts on watersheds in varying streamflow conditions. In addition, she conducts socio-environmental analyses to identify potential risks to food, water, and energy systems. Cielo aims to understand the hydraulic linkages between the socioeconomic and hazard landscape, with a goal of helping communities facing intersectional tensions in climate change. She has worked as a diversity, equity, and inclusion fellow at the Northeast Climate Adaptation Science Center and currently serves as a Diverse Knowledge Systems Fellow at the National Climate Adaptation Science Center. Additionally, she serves as the graduate advisor to the National Society of Black Engineers at the University of Massachusetts Amherst. Cielo is passionate about environmental and climate justice and enjoys community engaged research. She is currently supporting the National CASC in expanding efforts for diversity, equity, inclusion, and justice.
