Past and Ongoing Research
Hearing in Marine Mammals
Hearing is often the primary sense many marine animals use to detect predators, prey and conspecifics. Hearing is also crucial for navigation. In order to better understand how marine organisms use sound and thus perceive their environment, it is important to know how and what they hear. I am interested in finding out what many marine species hear and how this may fit into their sensory ecological niche.
Hearing in Cephalopods
We are currently looking at the hearing and neuroanatomy of squid and cuttlefish including their sensitivity to near-field particle velocity stimuli. Upon discovery that squid can detect sounds we are investigating if and how they might use this cue.
Marine Mammals and Noise
I have investigated how noise affects marine mammal hearing. This includes demonstrating sonar induces temporary hearing loss (temporary threshold shifts - TTS) and the relationship of sound duration and intensity (short duration sound must be of very high amplitude to induce TTS).
(Marine Mammal) Temporal Resolution
Localization of sounds is perhaps the most important function of hearing and identifying a sounds location is often aided by temporal cues. I am investigating how fast various species can recieve and process short sounds and the comparative relationship between marine species.
Acoustic Signals and Passive Acoustic Monitoring
Our research progresses fast, so this page is always in need of some updating
