RESEARCH INTERESTS

 

My long-term research goal is developing and popularizing the world’s leading computational models of stuttering, which will enable scientists to interpret the huge amount of neuroimaging and behavioral data on stuttering collected so far. Currently, I am utilizing the state-of-the-art models of speech production, DIVA and GODIVA, to interpret past experimental results, to design new experiments, and to predict their outcomes. The experiments use a multi-modal approach, combining several sources of data: functional Magnetic Resonance Imaging (fMRI), Diffusion Tensor Imaging (DTI), Electromyography (EMG), Magnetoencephalography (MEG), and acoustic and kinematic measurements.

I am interested in speaking conditions that alleviate stuttering: masking noise, prolonged speech, rhythmic speech, choral reading, altered auditory feedback, etc. As the mechanisms of these conditions are still poorly understood, speech therapies and fluency-enhancing devices are designed based on behavioral results with little attention to possible brain mechanisms involved. I suggest concrete testable hypotheses regarding the neural circuits involved in fluency enhancing, and demonstrate the merit of my hypotheses using computational modeling. I plan to collect empirical evidence to strengthen my hypotheses, and with a greater understanding of the mechanisms of fluency-enhancement, design some prototype devices.
