Before my studies, most previous research on large rivers in South America focused on the effects of perpendicular gradients of flooding on riparian plant species. My research took a biogeographical approach at a range of scales from the river basin to the riparian corridors, and resulted in the analysis of longitudinal as well as perpendicular gradients in a variety of riparian landscapes. My research produced ecohydrological explanations now used by many other researchers for other large rivers.
After earning my PhD, I have taught courses and seminars, supervised PhD, Master and BPhil undergraduate theses (see below) and taken a course on "Effective Tutoring and Assessment" offered by the University of Guayana. I designed and implemented the programs for PhD and Master studies in Environmental Sciences at the University of Guayana UNEG, where I spent 20 years doing research, teaching and administration in the fields of Environmental Management and Applied Ecology. I coordinated the Research Centre in Ecology and the Postgraduate Department in Environmental Sciences. I received grants for several research projects (listed below) and have published extensively. I am currently considered one of the top Researchers in Ecology in Venezuela. I participated on the Steering Committee of several international projects for Latin American and the Caribbean, the Guiana Shield and in a binational study of the Orinoco River Basin. I also organized several International and National Conferences. Throughout my career, I worked with local communities and emphazised the two-way exchange of knowledge with creole fishermen and indigenous communities. After my official “retirement, I continue working as an academic at UNEG participating in postgraduate teaching and actively working on the Orinoco Research Station, Orinoco Corridor Project.
