RESEARCH INTERESTS

SELECTED RESEARCH PROJECTS

My major research interests are animal behaviour and neurophysiology, namely understanding the social role of vocal communication signals and how sounds are produced and detected by the vertebrate nervous system. I am interested in the physiological mechanisms underlying auditory sensitivity  and how changes in the environment (eg. increasing noise pollution) can impact hearing, behavior and possible physiological adaptations.
Presently, my research lines focus on social behavior, vocal communication and auditory sensitivity in fish. I have been using the highly vocal Lusitanian toadfish (Halobatrachus didactylus, Batrachoididae) and, more recently, the zebrafish Danio rerio, as my major study organisms.
Ongoing research projects cover the following topics:  (1) ontogenetic development of multimodal communication; (2) developmental of auditory-vocal systems; (3) hormonal control of auditory sensitivity; and (4) effects of noise on early development and noise pollution.
A parallel project, in collaboration with The University of Hong Kong (Global Night Sky Brightness Monitoring Network), focuses on light pollution in Macau.
