Discover Your Career at Emory University

Emory University is a leading research university that fosters excellence and attracts world-class talent to innovate today and prepare leaders for the future. We welcome candidates who can contribute to the diversity and excellence of our academic community.

Description

 

 

 

We seek a postdoctoral fellow to study motor control and the biomechanics of sound production in songbirds and rodents. The positions will be part of an interdisciplinary, international consortium consisting of three nodes: the Sober Lab at Emory University (Atlanta, USA), the Vocal Neuromechanics Lab at the Department of Biology at the University of Southern Denmark (SDU, Odense, Denmark), and the Complex Flow Modeling and Simulation Lab at the University of Maine (Orono, USA). The open position is located in Atlanta, USA, but applicant will receive mentorship from and (post-pandemic) travel between all three research nodes.  

The positions are funded by the Novo Nordisk Foundation (Denmark) as part of the Interdisciplinary Synergy Programme along with the National Institutes of Health (USA). They are available as of October 2021, or until filled, for a three-year period.

Background
Although the physics of voice production is described in humans, experimental difficulties prevent systematic investigation of voice control and associated diseases. Consequently, we lack physics-based causal models connecting neural activity to sounds produced. In contrast, in songbirds and rodents - the best animal models for speech acquisition and neuropsychiatric communicative dysfunctions - we can probe the neural circuits controlling vocal behavior but lack insight in how their activity is transformed into sound by their vocal organs. In this interdisciplinary project, we will use state-of-the-art techniques from neuroscience, physiology, engineering, and biomechanics to integrate physics-based, computational models with novel experimental paradigms to causally link neural activity to sound production in songbirds and rodents.

Preferred qualifications
We are looking for an applicant with:

  • a PhD in bio-imaging, biomechanics, engineering, neuroscience, or a related field

    Other experiences, such as signal analysis, and/or programming (C++, Matlab, or equivalent) present a distinct advantage.

    We seek scholars with one of the following distinct profiles, but possibly also other types or researchers:
  1. Experience in biomechanics. We will use combined in vitroand ex vivo approaches studying effects of muscle recruitment on sound production. Experimental techniques: high-speed imaging, 3D motion capture, muscle mechanics, kinematic analysis, mechanical tissue properties and microscopy. 
  2. Experience in micro-surgical experimental procedures. Experience with EMG implantation or other muscle (or nerve) surgery is ideal, but any kind of micro-surgical experience is a strong asset.

Our research

The Sober Lab investigates how the brain controls complex behaviors and improves motor output through practice. We use songbird and rodent species to investigate how networks of neurons and muscle fibers control vocal and forelimb behavior, respectively. To do so, we combine behavioral manipulations, neurophysiological and muscle (EMG) recordings, and computational approaches.


The Vocal Neuromechanics Lab uses a combination of experimental and computational approaches to study motor control and physical mechanisms of sound production in the vocal vertebrates. We use and develop methods from biomechanics, electrophysiology, acoustics, and behavior at different levels of organization (cellular, whole organ, in vivo).

 

The Complex Flow Modeling and Simulation Lab focuses on modelling complex flow phenomena using high-fidelity immersed boundary based computational method incorporating with massive parallel computing. Current research interests include complex biomedical, physiological, and biological flows with complex, moving boundaries and flow structure interaction as well as renewable energy applications.
