My research aims to understand the role of cultural and evolutionary processes in shaping learned animal vocal signals as well as the macro-evolutionary consequences of cultural transmission. I tackle these questions by studying the communication systems of neotropical taxa, making use of 'single species' behavioral studies, comparative phylogenetic methods and cutting-edge acoustic analyses.
During my PhD I worked on hummingbird signaling behavior, and also explored the evolution of learned vocal signals in other groups using comparative analyses. Currently, my research as a postdoc at the Lab of Ornithology focuses on expanding these research avenues by looking at the evolution of learned vocalizations in hummingbirds using phylogenetic comparative methods.
I am also deeply involved in the development of computational tools for bioacoustic analyses. I have created the R package warbleR that provides functions to streamline high-throughput acoustic analysis of animal sounds. More recently, I made available two new R packages (Rraven and NatureSounds) that aim to simplify the use of R for bioacoustic research. New functions as well as other analyses are detailed in my blog Bioacoustics in R.
