Estudié CC Biológicas en la Universidad de Granada (UGR) (1979-1984), donde también me doctoré en 1991. Fui becario predoctoral del MEC en la UGR (1986-1990) para realizar mi tesis sobre taxonomía y diversidad de macroinvertebrados quironómidos de los ríos de Sierra Nevada. Como postdoctoral, estuve un año en la UGR, y realicé dos estancias en la Universidad de Pittsburgh (USA) y en la Estación Biológica de Lunz (Austria). También he realizado estancias de investigación más breves en el centro CNRS y la Universidad Paul Sabatier de Toulouse (Francia), el centro EAWAG de Zúrich (Suiza) y el IGB de Berlin (Alemania). Durante estas estancias, y posteriormente, he investigado sobre ecología acuática y fluvial, en particular sobre la dinámica del ecotono río-ribera.

Desde 2018 soy catedrático de ecología en la Universidad de Almería, donde continúo investigando en ecología acuática, e imparto docencia de diversas asignaturas de ecología general y acuática de grado (Ciencias Ambientales) y master.

INVESTIGACIÓN

Mis intereses de investigación transitan por las líneas de la biodiversidad y el funcionamiento de los ecosistemas acuáticos, con incursiones en aspectos aplicados relacionados con la evaluación y la gestión de estos ecosistemas.

GRUPO DE INVESTIGACIÓN: Ecología Acuática y Acuicultura (RNM-346)

PARTICIPACIÓN EN REDES (REGIONALES/NACIONALES/INTERNACIONALES)

Soy miembro de la red internacional GloBE (https://www.globenetwork.es/: GLoBE is an international network of freshwater ecologists, which main aim is to study the patterns and drivers of stream ecosystem functioning at the global scale).
