Laboratory of Aquatic Bioacoustics
I have retired from my facutly position
and no longer have a lab.
Thus, I no longer supervise
UMD undergraduate students, graduate students, or postdocs.
I will, however, continue my active
involvement in research and other activities through collaborations
and outreach. Some of my current activities include:
My research has primarily involved the study of hearing by aquatic organisms. Most
work focuses on fishes,
although studies have been done with other non-mammalian vertebrates.
Our fish studies have focused on various aspects of hearing that range
from behavioral investigations to determine what an animal can hear
to physiological investigations of the responses of the ear and
The majority of my work
is now involved with studies on the
effects of human-generated
(anthropogenic) sound on aquatic organisms. This has resulted in
a series of studies that explored behavioral and physiological
effects of increased ambient sounds on fish. These
studies have asked about effects of seismic air-guns, pile driving,
and general increases in background sound levels on fish hearing and
Investigations in the
past have ranged
from basic questions concerning evolution and mechanisms of sound
detection, investigations of hearing sensitivity, studies on the
anatomy and ultrastructure of the ear, and many other topics (see
publications link at left).
Effects of Noise on
Over the past several years, I have been
involved in the organization of several international meetings on
the Effects of Noise on Aquatic Life. Another meeting took place in
2013 in Budapest, with the proceedings published as a
book co-edited with Dr. Anthony Hawkins.
The next meeting will take place
in Dublin in July 2016.
For the past several years I have been working
with colleagues from around the world to develop "guidelines" on the
effects of noise on fishes and sea turtles. The report of this work
will be published in July 2014 as:

recently published our 25th co-authored paper.

We are also very proud and grateful that our former students
and many colleagues have published a book in our honor,
