Competitive research grant (2007) awarded by the Carlsberg Foundation, Copenhagen, Denmark. RESEARCH EXPERIENCESpeech perception by human listeners November 2010 – Present Modeling of speech perception in fluctuating maskers: Research in why speech intelligibility index models specifically fail to predict speech intelligibility in speech related maskers like interfering talkers or speech envelope modulated noise. Psychoacoustic tests on normal hearing listeners on the possible effect of the dynamic range of speech and modulation rate. Research in hearing and vocal communicationMarch 2007 – October 2010 Auditory feedback: Research in the control of vocal formants (analogue to human speech formants) by auditory feedback in a songbird. Performed x-ray cinematography and video movement analysis. Results showed songbirds control formants actively by auditory feedback and responded in a similar way to humans. Directional Hearing, Post Doc2009 – December 2009 (Grant awarded by Oticon) Discovery of an air filled cavity in the skull of birds connected to the inner ear which may play an important role in directional hearing. Experiments involve 3D reconstruction of inter-aural cavities. Acoustic systems modeling in collaboration with professor in physics Neville Fletcher, University of New England, Canberra, Australia. Laser vibrometry measurements of eardrum vibrations. Histology. Computational Neuroscience, Animal Navigation and Orientation 2007 – 2010 Formulation of theoretical and computational model of neural integration to explain the hot research topic of the mysterious and intriguing effect of light on the magnetic sense of navigating animals. Well-received and complimented by significant peers: “This is the most creative piece of work I've seen in a while, and gives the animal navigation community a new way of thinking about a thorny problem...has great explanatory power... Frankly, I wish I had come up with the idea!” [Anonymous reviewer]; “… a new and really very useful model to possibly understand bird magnetic orientation… a clever idea that should be followed up…” [Professor Almut Kelber]; “…fascinating and highly provocative paper!...” [Professor Uwe Homberg]; “…an interesting and thought provoking contribution to the debate concerning the mechanism(s) of magnetoreception in higher animal…” [Professor John Philips]. Comparative psychoacousticsOctober 2003 – November 2003 Collaboration with renowned Professor Robert Dooling conducting research into a potential effect of lowering hearing thresholds of speech-like harmonic complexes by amplitude (AM) and frequency modulation (FM). Conducted on zebra finches which are important animal models in comparative research of human hearing, speech, and vocal learning.
