Ph.d. stipend available (Deadline February 12 2009):

Echolocation in bats – the role of ear and face morphology for sound emission and perception

Supervisors: Annemarie Surlykke Institute of Biology, SDU and John Hallam, The Maersk Mc-Kinney Moller Institute, SDU.

SDU, University of Southern Denmark, Odense Denmark.

Bats use echolocation or “bio-sonar” to orient and find prey in the dark. They emit short high frequency sound pulses and listen for the echoes reflected from surroundings to orient in space. Bats from different families emit sounds either through the mouth or through the nose. Bats emitting sound through the nose have elaborate skin folds or “nose-leaves” around the nostrils. The shape and size of the sound emitting structures (mouth or nose) is believed to strongly affect the directionality or shape of the emitted sound beam. The shape of the sound beam will subsequently strongly affect the reflected “echo-picture” of the scene. A broad beam will ensonify objects within a wide angle, whereas a narrow beam will restrict the bat to a narrow angle of view, but perhaps reach further ahead than the broader beam. Thus, the received echo is dependent on the outgoing sound. However, the returning echo also depends on the shape and size of ears. This filtering is referred to as “head-related-transfer-function” (HRTF) and is well described for human listening, but not at all for bats in spite of the obvious importance, which is reflected in the very diverse and sometimes bizarre morphology of bat faces.

The goal of the project is therefore to record and use echolocation sounds from real bat species to determine the effect of morphology on directionality of the emitted beam and HRTF of returning echoes. Based on these data we want to develop algorithms to effectively simulate the sound in 3-D. 3-D simulations of sounds fields will be used for implementing bio-mimetic robots using sound (echolocation) to orient in space and to discriminate between objects.

An EU-funded (FP7) project, ChiRoPing ( ) focuses on the engineering aspects of building bio-mimetic bat-robots, using as models four bat species with different morphology and echolocation sounds, but overlapping prey capture strategies. The ChiRoPing project seeks to build physical and mathematical models of the bats and compare structure, function and performance to the real bats. Thus, this present project will interact with and complement the ChiRoPing project. Biology, SDU, also has a Marine Research Facility, “Fjord and Baelt”, with captive trained porpoises, which gives a unique opportunity to compare performance of bio-sonar systems in air and water and study how structure is linked to function in two media posing different constraints on the systems.

This project is offered within the research training programme SNAK. The project is conditioned on funding from the Danish Agency for Science, Technology and Innovation.

NB: Deadline for “Declaration of Interest” is February 2009 – Project 7, see general description:



Declaration of interest - PhD Research Fellowships in Natural Sciences – Job ID 083021 – Re-announcement of Projects 6 and 7

Job description:

The Faculty of Science offers two PhD Research Fellowships at the Faculty of Science available as of 1 April, 2009.

The fellowships may be sought by students who wish to obtain a PhD degree, either with or without a previous Master's degree, in a field relevant to one or more of the below mentioned PhD projects.

The PhD programme at the Faculty of Science can be completed as a three-year study with a previous Master’s degree or as a four-year study without a previous Master’s degree. Applicants without a relevant Master's degree must have passed a minimum of 240 ECTS-points (Bachelor’s degree plus one year (60 ECTS-points) of graduate study).

The fellowships are available within the following two projects:

Project 6) Sound localizing robot

Project 7) Echolocation in bats – the role of ear and face morphology for sound emission and perception

Further information concerning the projects: Please contact one or more of the supervisors mentioned under the project descriptions.

Further information about the PhD study can be found at the
homepage of the University.

Application, salary, etc.:

The PhD Research Fellowship is salaried in accordance with the Danish State Education Grant and Loan Scheme Authority, and with the agreement on salaried PhD students between the Ministry of Finance and the Danish Confederation of Professional Associations, AC.

The successful candidates will be enrolled at this University in accordance with Faculty regulations and the Danish Ministerial Order on the PhD Programme at the Universities (PhD order).

Must be made in the form of a declaration of interest and should include the following

• A letter stating the interest, motivation and qualifications for the project in question (max two pages)
• Detailed CV, including personal contact information
• Certified copy of diploma
• Previous research experience and list of publications, if any.
• References

Additional information may be requested and the application process may include an interview before the final decision is made.

The declaration of interest will be evaluated by a committee comprised of the supervisor of the project and one or two members of the PhD Assessment Committee at the Faculty. The Assessment Committee selects one or two students from each project who are each given one month to prepare a project and research plan and an application for enrolment at the PhD School at the Faculty of Science.

All applications should be marked: “Job ID 083021” as well as one (or both) of the above mentioned project IDs.

Employment as a PhD Research Fellow is for three or four years. Employment stops automatically at the end of the period. The holder of the Fellowship is not allowed to have other paid employment during the three/four-year period.

The University encourages all interested persons to apply, regardless of age, gender, religious affiliation or ethnic background.

Applications must be forwarded by e-mail (in Adobe PDF format or Word XP 2003 legible format) to the following e-mail address: m("","anc");"> and should be addressed to: The Faculty of Science, University of Southern Denmark, Campusvej 55, DK-5230 Odense M.

Incomplete applications and applications received after the deadline will not be considered.

Application deadline is 12 February, 2009 at 12 o’clock noon for appointment 1 April, 2009.

Employment starts:  01.04. 2009
Closing date 12.02. 2009 at 12 noon
Location: Odense, Denmark
