Postdoctoral Fellowship in
the Study of Sensory - Neural Mechanisms Controlling the
A postdoctoral position is available to study voice control in the
Speech Physiology Lab at Northwestern University. We study
control of voice fundamental frequency and intensity during speech and
singing using a sensorimotor perturbation paradigm. Speakers or
singers receive perturbed voice pitch or loudness feedback on line,
and we analyze their vocal and EMG responses in an effort to
understand neural mechanisms controlling the voice. Subjects
will be tested in a variety of speaking tasks and/or singing tasks.
We will also be applying topical anesthetic to the vocal folds and
mechanical perturbations to the larynx to look at the influence of
kinesthetic and/or proprioceptive receptors on the responses to pitch
or loudness-shifted voice feedback. EMG recording will be made
from intrinsic laryngeal muscles concurrently with the voice
perturbation studies. Opportunities also involve contributing to the
refinement of a mathematical model of neural mechanisms controlling
The main laboratory is located on the Evanston campus of Northwestern
University in the Department of Communication Sciences and Disorders.
We are also building a new lab at the Northwestern University Medical
School. Northwestern University has a large and active
Neuroscience community and there are many opportunities for
collaboration with neuroscientists in other departments. This research
project is supported by a grant from NIDCD, NIH.
The position is available immediately, and we will be searching for a
candidate until we fill the position. Funding for the position
is available for three or four years.
Applicants with experience in acoustics, speech science, voice, music,
psychology, mathematical modeling or neurobiology are encouraged to
apply. Applicants should submit a cover letter, a curriculum
vitae, and the names and addresses of three references to:
