Research Interests

My research has focused on upper Andean river systems (≥ 2000 m.a.s.l.) as part of the Freshwater Ecology Management (FEM) group at the University of Barcelona (Spain). Specifically, I have focused on the management, ecology and distribution patterns of acuatic macroinvertabrate communities as well as bio-evaluation of rivers. My research has produced an evaluation tool to determine the ecological quality of upper Andean rivers (Multimetric Index for the Evaluation of Ecology of Upper Andean Rivers, IMEERA (span.)) and a program (CABIRA (span.): Biological Quality of Upper Andean Rivers) to calculate metrics for evaluating river ecology and IMEERA. In addition, I have become increasingly interested in chironomids of upper Andean rivers. Chironomids are poorly studied organisms that are an important part of the aquatic macroinvertebrate community and their food chain. In collaboration with members of FEM, I have been develloping research looking at their distribution and taxonomy.
