Douglas H. Whalen, Ph.D., Director Douglas H. Whalen joined the GC faculty in spring 2011. He is a distinguished professor in the Speech-Language-Hearing Sciences program and has a joint appointment in the Linguistics program. Dr. Whalen is also Vice President of Research at the Yale- and University of Connecticut-affiliated Haskins Laboratories (where he has been a researcher for thirty years) and is one of the world's leading scientists in the fields of speech and phonetics.

The central theme of Dr. Whalen's research is the interrelation of speech perception and speech production, and how the two constitute a single system and cannot be understood in isolation from one another. His work addresses a wide variety of populations (from developing infants being raised in different language environments to adult speakers of American English and Native American languages) and techniques (including behavioral approaches, MRI, ultrasound imaging of the tongue, and acoustics). He has served as a program officer at the National Science Foundation, overseeing two programs, Documenting Endangered Languages and Cognitive Neuroscience. He is the founder and Chair of the Board of Directors of the Endangered Language Fund, a non-profit organization sponsoring research on the documentation of languages that are falling silent, with a further emphasis on revitalization efforts.

Dr. Whalen also serves on the editorial boards of the Journal of Phonetics and Phonetica. He was elected a fellow of the Acoustical Society of America in 2008, and to the American Association for the Advancement of Science in 2013. He received his BA from Rice University and his Ph.D. (in Linguistics) from Yale University.

Graduate Students


Reethee Antony Research Interests: examination of speech in noise processing in adults and children, CVC harmony process in the Tahltan language, and the effects of digital signal processing in normal hearing listeners.


Micalle Carl is a doctoral student in the Speech-Language-Hearing Sciences program. Micalle received her M.A. in Speech-Language Pathology from Lehman College and is a NYS-licensed practicing clinician.  Her research interests include motor speech disorders, the relationship between articulation and acoustics, and speech intelligibility. She is particularly interested in studying the articulatory characteristics and associated intelligibility of speech in individuals with developmental disabilities.

Katherine Dawson is currently a 3rd level doctoral student in the speech lab. She received her undergraduate degree at the University of Bath (UK) in Applied Biology and worked in neuroscience research and the charity sector before entering the program. Her current focus is speech in aging and degenerative neurological conditions. She is particularly interested in how motor control and cognition changes across the lifespan, and the cognition-motor interface.

Stephanie Kakadelis is a Ph.D. student in Linguistics. Her research interests are in phonetics, phonology, articulation, and the phonetics of laryngeal features. Her current research is investigating the articulation and acoustics of languages which do not have any laryngeal (voicing) contrasts in their consonant inventories.

Jaekoo Kang is a doctoral student in the Speech-Language-Hearing Sciences program. His research interests include the mapping between articulation and acoustics (i.e., speech inversion), investigating the speech perception-production link, and sequence modeling of speech data with corresponding linguistic units (e.g., forced alignment of phonemes or VOT).

Grace Kim-Lambert is currently a 2nd level doctoral student in the Speech-Language-Hearing Sciences program. Her research interests include speech perception and production, and the link between the two. Her research goal is to further an understanding of the intersection between vision and hearing in cross-modal speech perception, specifically, to examine speech production and perception abilities among people who are congenitally blind, focusing on the perception of place of articulation in American English consonants.

Richard Lissemore is an internationally acclaimed singing teacher, voice researcher, and performance coach who is equally adept at techniques for classical as well as popular vocal styles such as musical theater, rock, pop, R & B, and jazz. He has taught hundreds of students who perform on Broadway, at Carnegie Hall, at New York‘s Radio City Music Hall, in both American and international touring productions and in theaters throughout the world. He is especially well known for his innovative and entertaining master classes in vocal technique and performance, which have been presented regularly in New York, Canada, Korea, Mexico, and Germany.  As a guest speaker and clinician, he has taught workshops and masterclasses in voice pedagogy and performance for The Voice Foundation, the National Association of Teachers of Singing (NATS), the British Voice Association (BVA) at London’s Royal Academy of Music, the New York Singing Teachers Association (NYSTA), Columbia University, the University of Cincinnati’s College-Conservatory of Music, to name a few.  
Educated at The Juilliard School (Oren Brown), Cincinnati’s College-Conservatory of Music (Andrew White), and Rutgers University (Valorie Goodall), Mr. Lissemore enjoyed a varied performance career that encompassed opera, music theater, orchestra concert, oratorio, and voiceover for radio and television. His professional affiliations include Actors’ Equity Association (AEA), the National Association of Teachers of Singing (NATS), and The Voice Foundation.
He is presently pursuing a Ph.D. in Speech-Language-Hearing Sciences at The City University of New York, where he is a Graduate Teaching Fellow in the laboratory of Dr. Douglas Whalen. His research interests are centered around articulatory effects on vocal tract transfer functions in professional singers. Experimental protocols include electroglottography (EGG), acoustic analysis, ultrasound of the tongue, Optotrak infrared tracking of mouth and head positions, and VoceVista. Additionally, he is a founder of The Singing Voice Science Workshop, which is an annual gathering of voice researchers, singing teachers, and speech-language pathologists at Montclair State University in Montclair, NJ.

Ai Mizoguchi is a 3rd level doctoral student in the speech lab. She is interested in speech production and perception of second language learners. She is currently investigating tongue movements in speech production using ultrasound imaging.

Sejin Oh is a Ph.D. student in Linguistics. Her research interests are in phonetics, laboratory phonology, second language acquisition, and prosody. Her current research is investigating unstressed vowel reduction in Bulgarian. Future research plans include investigating positions of the tongue and jaw associated with vowel reduction using EMA.

Kevin Roon is a post-doctoral associate in the speech production lab. He is interested in how ultrasound feedback can be used to aid in the acquisition of non-native language sounds, both in speech and in singing. As well as this work, his research interests include the process of phonological planning in speech production, the links between speech perception and production, and the nature of phonological representation. He also has a longstanding interest in Russian phonetics and phonology.




Eric Jackson received his Ph.D. in 2015 for a dissertation entitled "Variability, stability, and flexibility in the speech kinematics and acoustics of adults who do and do not stutter." This work examined kinematic variability in stuttering and non-stuttering speakers, and it applied a dynamical perspective for a fuller explication of the patterns. Eric is also a speech-language pathologist with a focus on working with children and adults who stutter. He is currently an Assistant Professor in The Department of Communicative Sciences and Disorders at New York University.
