Professional wildlife biological contractor focusing on bioacoustic survey work, data analysis, and biological research. With10 years experience, I have managed marine and terrestrial survey teams, conducted large-scale data analysis focusing on the distribution and diversity of focal species, thoroughly troubleshooted new and innovative survey equipment, and have published multiple peer-reviewed manuscripts and technical memorandums.
Currently, I am working full-time at Aarhus University, Institute of Bioscience in Marine Mammal Research.
