Current Lab Members
Frank Guenther, Ph.D. is a Professor in the Departments of Speech, Language & Hearing Sciences and Biomedical Engineering at Boston University. He is also a Research Affiliate at the Picower Institute for Learning and Memory at MIT, a Faculty Member in the Harvard/MIT Speech and Hearing Bioscience and Technology Program, and a Visiting Scientist in the Department of Radiology at Massachusetts General Hospital. Dr. Guenther is a computational and cognitive neuroscientist specializing in speech and sensorimotor control. His research program combines theoretical modeling with behavioral and neuroimaging experiments to characterize the neural computations underlying these faculties in humans. Dr. Guenther also develops brain-computer interfaces to restore synthetic speech and other communication skills to paralyzed individuals. His research has been covered extensively in the science and popular media, including television spots on CNN News, PBS News Hour, and Fox News; articles in popular science magazines Discover, Scientific American, and Popular Science; and popular press coverage in Esquire, Wired, The Boston Globe, and BBC News.
Jason Tourville, Ph.D. is a Research Assistant Professor in the Department of Speech, Language & Hearing Sciences and Center for Computational Neuroscience and Neural Technology at Boston University. He received his B.A. from Oberlin College and his Ph.D. in Cognitive and Neural Systems at Boston University. He is a cognitive and computational neuroscientist primarily focused on mapping the brain regions involved in speech motor control. His research combines mathematical modeling with functional and structural brain imaging to study the neural mechanisms underlying normal and disordered speech, including persistent developmental stuttering, apraxia of speech, spasmodic dysphonia, and autism. Dr. Tourville also has an extensive background in human neuroanatomy and MRI-based brain morphometry that he uses to develop expert-guided semi-automated brain region labeling methods.
Joseph Perkell, Ph.D. is a Senior Research Scientist in the Department of Speech, Language & Hearing Sciences. He is also a Research Affiliate at the Research Laboratory of Electronics at the Massachusetts Institute of Technology. Dr. Perkell has been engaged in research on speech motor control since 1965. His former laboratory, in the Research Laboratory of Electronics at MIT, developed EMMA, the first electromagnetic articulometer system shown to have accuracy and reliability sufficient for rigorous research on speech kinematics. From the early 1990’s until 2012, Dr. Perkell headed the Speech Motor Control Group in RLE and was PI on two long-running R01 grants from NIDCD. The group published a number of carefully conducted, hypothesis-driven, methodologically sophisticated studies of speech production: on biomechanical constraints and motor control strategies, including the role of hearing. For its last 15 years, the group collaborated closely with Prof. Guenther, whose DIVA model provided the theoretical framework for research in both projects, guiding work on brain mechanisms and the influence of these mechanisms on speech kinematics and acoustics. Dr. Perkell was also a participating faculty member in the Harvard-MIT Graduate Program in Speech and Hearing Biosciences and Technology Program, for which he served on the program’s admissions committee and supervised graduate students. Dr. Perkell’s most recent review papers showed how his group’s work was consistent with a coherent theoretical framework that modeled relations among brain mechanisms, audition and speech motor control.

In his private practice he also works as a statistical consultant, analyst, and methods/software developer. In addition to providing modeling and statistical support to research groups in the field of computational neuroscience, some of his ongoing projects involve functional connectivity magnetic resonance imaging (fcMRI) analysis methods, the application of functional localizers to investigate the selectivity of language-related areas, and method development for speech restoration in subjects with locked-in syndrome.
Liam Jackson is a research associate for the Guenther Lab. He received a Bachelor’s Degree in biochemistry from the University of Massachusetts in Amherst. Originally with plans to pursue clinical medicine, his interests shifted toward medical devices and the engineering supporting them. Now a recent graduate from Boston University, he holds a Master’s Degree in Biomedical Engineering and focuses primarily on the application of machine learning techniques to medical research. He investigates cortical regions and their behavior during speech production. By training, tuning, and systematically modifying classification models, his efforts aim to establish the importance of signal patterns and their sources within the brain.
Alexander Acosta recently graduated from BU with a B.A. in Neuroscience and Linguistics. At the lab, he is helping develop the experimental paradigm and software for behavioral auditory perturbation experiments. For hobbies, Alex likes playing the violin and piano, learning languages, and playing cards with his friends. Alex hopes to continue his studies into the power of human audition after his undergrad and one day wants to do medical work abroad and conduct research.
Adanna Thomas recently graduated from BU with a B.A. in Neuroscience with a Linguistics minor. She is currently helping collect data for auditory perturbation experiments. Her hobbies and interests include visiting museums, embroidery, horror, and music theory. Adanna hopes to continue doing research in neurolinguistics in the future with a possible focus in child speech development or speech language pathology.
Andrew Meier, Ph.D., is a Postdoctoral Fellow in the Department of Speech, Language, and Hearing Sciences at Boston University. Andrew received his B.A. in Liberal Arts from St. John’s College, New Mexico, and his PhD in Neuroscience from Washington University in St. Louis. His research investigates neuroplasticity and learning in speech motor control. Currently he is involved in a collaboration between the Guenther Lab and Dr. Mark Richardson at Mass General Hospital, designing and analyzing speech science studies with patients undergoing surgery for deep brain stimulation. In these studies, Andrew seeks to understand the physiology of the cortical, basal ganglia, and thalamic networks that underlie the learning of new speech motor patterns. These studies have implications for understanding early speech motor learning, including the development of speech disorders, such as stuttering and apraxia of speech.
Hannah Rowe, Ph.D., is a Postdoctoral Fellow in the Department of Speech, Language, and Hearing Sciences at Boston University.
