Degree

Ph.D., Neuroscience, University of Southern California, 2007

Research and Professional Interests

Professor Aronoff’s research focuses on cochlear implants, with particular interest in bilateral implantation. His work examines how information is combined across the ears and how to divide information between two ears for optimal cochlear implant performance. He developed special software that enables him to create custom processors for cochlear implants, and co-developed a new test to assess whether the processors increase spectral resolution, a key requirement for improving the ability to understand speech in noisy environments.

Research and Professional Interests

Pasquale Bottalico earned his bachelor’s degree in Telecommunications Engineering from Univeristà Mediterranea di Reggio Calabria (Italy), while simultaneously pursuing a degree in Opera Singing at the F. Cilea Music Academy of Reggio Calabria (Italy). In 2005, he moved to Turin where he earned his master’s degree in Telecommunications Engineering from Politecnico di Torino (Italy). For his master’s thesis, Dr. Bottalico combined his studies of engineering and music to explore musician perceptions of acoustics and the correlation with objective index from ISO 3382.
 
Dr. Bottalico earned his PhD in Metrology, studying acoustics with particular attention to the uncertainty of measurements and statistical analysis of data. For his dissertation, he investigated classroom acoustics of primary schools and its relationship with safety, examining the students and the teachers separately. Specifically, he: 1) described the speech intelligibility in the classroom, which affects students’ learning; and 2) examined how the acoustical features of a classroom can influence vocal performances. Dr. Bottalico is particularly interested in the professional voice user and singer techniques, as well as the definition and the quantification of vocal load. Other fields he is interested in are Speech Intelligibility, Room Acoustics and Musical Acoustics. Bottalico is also a professional chorister, performing under such prestigious directors as Rafael Frühbeck De Burgos, Yuri Ahronovitch, Jeffrey Tate, Juanio Mena, Gianandrea Noseda, Ottavio Dantone, Wayne Marshall, Helmuth Rilling, Christopher Hogwood, Robert King and Ivor Bolton.

Degree

PhD, Cognitive Psychology, State University of New York at Buffalo, 2016

Research and Professional Interests

Dr. Flaherty’s research focuses on speech understanding in children with and without hearing loss. In particular, her research program investigates the way that age and listening experience impact speech perception for younger listeners in complex acoustic environments. Her most recent work aims to characterize children’s immature ability to use acoustic voice differences between talkers to improve speech-in-speech recognition. In addition to improving our understanding of the factors that contribute to children’s ability to recognize speech in multi-talker environments, the long term goals of her research include finding ways to improve communication outcomes for children with hearing loss.

Research and Professional Interests

Professor Hadley teaches language development and language disorders in early childhood. Her research examines the nature of specific language impairment (SLI) in early childhood, a high incidence condition characterized by extraordinary difficulty with language acquisition in the presence of otherwise typical development.

Professor Hengst teaches courses in adult-onset cognitive-linguistic communication disorders, augmentative and alternative communication, and normal processes of language-use and development across the lifespan. Her research interests include:

  • Situated studies of discourse practices, especially focusing on individuals with aphasia and their routine communication partners.
  • Socio-historic and practice theories that integrate communication, learning, and development within a unified framework.

Research and Professional Interests

Dr. Ishikawa's clinical and translational research focuses on understanding how voice disorders affect speech intelligibility. The ultimate goal of her research is to generate knowledge that will guide clinical decision making for directly addressing patients’ communicative ability. Dr. Ishikawa's research program lies at the interface of psycho- and physical-acoustic science, linguistics, computer science, and bioinformatics. In particular, her lab is working on the development of a novel automatic speech analysis tool and a perceptual model that incorporates environmental noise for clinical intelligibility measurement.

Ph.D./Au.D., Speech and Hearing Science/Audiology; University of Iowa, 2014

Research and Professional Interests

Dr. Mertes studies the ascending and descending auditory pathways in individuals with normal hearing and with hearing loss. He uses a combination of otoacoustic emissions, auditory electrophysiology, and perceptual measures. The long-term of goals of his research program are to determine how sound perception is driven by the interconnections between the peripheral and central auditory systems, to delineate the effect of hearing loss on these interconnections, and to determine the impact of potential treatments such as auditory training when these interconnections are impaired.

PhD, Speech, Language, and Hearing Science, University of Arizona, 2011

Research and Professional Interests

Dr. Monson's research interests center around auditory neurodevelopment and the development of speech/voice perception.  His research program aims to answer a fundamental question in neuroscience:  How does experience with the environment affect auditory neurodevelopment and perception?  His work focuses on two major themes: (1) auditory neurodevelopment in preterm infants, and (2) the contribution of very high-frequency hearing capability and hearing loss to speech/voice perception for both children and adults.  In each case, the long-term goal is to improve the auditory experience for individuals who face communication difficulties.
