PhD, 2008, Geography, University of Colorado
MS, 2003, Environmental Engineering, University of Washington
BS, 1997, Forest Engineering, Universidad Distrital, Bogotá
Research Areas: 
  • Engineering for Sustainable Forestry
  • Forest Soils and Watershed Processes
My research interests are focused on the interactions between fluvial geomorphic, hydrologic, and ecological processes. Recent and current investigations include: (1) Climate change impacts on soil erosion and water temperature at the continental scale; (2) modeling of rainfall-runoff response at the event scale in forested ecosystems; (3) hydrologic modeling of daily flows; (4) interactions between stream sediment transport and algal production; and (5) study of the relationship between the riparian area and channel morphology under different degrees of urbanization. My research strategy includes intense field-based studies and modeling efforts of both field generated data and regionally available data sets. The goal of my research program is to understand hydrologic processes and to formulate predictions of natural and anthropogenic disturbances that contribute to the sustainable management of forests and river systems.
Native of Bogotá, Colombia, where she received her BS in Forestry Engineering (1997). She later worked in the private sector in environmental consulting for 3 years. She completed her MS. in Environmental Engineering at the University of Washington (2003) and her PhD in Physical Geography at the University of Colorado (2008). Dr. Segura was a Postdoctoral Fellow at NCSU for the Forestry Department (2008-2010) and then for the Marine, Earth, and Atmospheric Sciences department (2012-2013). She joined the Department of Forest Engineering, Resources, and Management at OSU in December 2013.
