He has developed several research projects all dealing with acoustics, animal behaviour and ecology. His work is internationally acknowledged and he is an expert in animal communication and biodiversity assessment through acoustic techniques. He is considered a leader of the recent emergence of ecoacoustics, a new scientific discipline that combines acoustics and ecology at a large spatio-temporal scale. He developed the R package 'seewave' which is used in more than 110 countries by researchers in bioacoustics and ecoacoustics, and also in speech analysis, telemetry, medical sciences, geology, and spatial engineering.
