I am a full professor in Environmental and Water Resources Engineering in the Department of Civil Engineering and Surveying and the Director of the Environmental Engineering Laboratory (EEL) at the University of Puerto Rico, Mayagüez. Before this, I led the groundwater office at Greg Morris and Associates (1999-2001), and directed several hydrologic investigations while working with the U.S. Geological Survey (1988-1992). My expertize is in contaminant and subsurface hydrology. I have directed laboratory, field-scale, and modeling investigations of karst systems in the academic, government, and private sectors. In particular, I have expertise include topics in: groundwater flow modeling; aquifer testing, hydraulic characterization, water quality sampling and monitoring; spatiotemporal assessment and potential exposure of legacy and emerging contaminants; and characterization and quantification of fate and transport processes. My current work integrates multidisciplinary efforts to assess contaminant exposure and public health impacts in karst regions. I have served in several review panels for the National Science Foundation and the National Research Council. I have received numerous awards through my career, including: Distinguished Professor in Civil Engineering; Innovative Woman in Engineering Education; and Ford Foundation Fellowship.
