Dr. Alba Solsona Berga

Post-doctoral Researcher

Dr. Alba Solsona Berga received her BS in Biology from the University of Barcelona in 2012, her MS in Biological Oceanography from the University of Vigo in 2013, and her PhD from the Polytechnic University of Catalonia, Spain. Her research focuses on automated detection and classification techniques for acoustic signals, and how anthropogenic noise and environmental variables influence habitat use of these cetacean species. When she’s not wrestling with MATLAB, she likes to spread the knowledge and inspiration of biomimicry for sustainable innovations.

Annebelle Kok

Dr. Annebelle Kok

Post-doctoral Researcher

Dr. Annebelle Kok investigates how noise disturbance changes the behavior of marine organisms. Her research includes the study of long-term acoustic recordings to elucidate patterns of behavior in cetaceans and fish. She received her BSc in Biology and MSc in Evolution, Biodiversity and Conservation from Leiden University in 2010 and 2013, respectively. After working as a freelance researcher for two years, she started her PhD position on the effects of anthropogenic noise on predator-prey relationships in odontocetes and fish at Leiden University, which she completed in 2020. Aside from research, she enjoys sharing her enthusiasm for the natural world with the general public.
