Post-Doc Research Associates
Dr. Eduardo Ribeiro da Cunha is a postdoc working on river-floodplain ecology and development of RIV WebScape, an individual-based simulation model of fish population and food web dynamics. This spatially explicit model simulates fluvial landscapes and ecological processes in response to scenarios of hydrology, temperature, and other factors. Eduardo received his Ph.D. from the Universidade Estuadual de Maringá in Brazil where he studied community ecology in aquatic habitats of the Paraná River floodplain as a research assistant with that university’s Long-Term Ecological Program. He was a visiting scholar in the Aquatic Ecology Lab during 2016, and in 2018 he began work as a postdoc in the lab.
Dr. David Saenz is a postdoc working on the physiological ecology of Neotropical fishes in the order Gymnotiformes, all of which are weakly electric. While working towards his doctoral degree in the Aquatic Ecology Lab, David conducted research on the neurophysiology of electrogeneration and electroreception as well as ecological and evolutionary patterns of electric organ discharge patterns and electroreceptor distributions. He also collaborated on research on fish community ecology and evolutionary ecology in rivers in Texas, Central and South America, and Africa. David also is collaborating on a synthesis of metrics used for fish functional traits.
