Callier Center for Communication Disorders

Callier Postdoctoral Program

Every two years, since 2008, the Callier Postdoctoral Program admits two new Postdoctoral Fellows. The goal of the two-year program is to provide a vibrant, interactive community of researchers for the Postdocs to create an independent line of research that builds on or collaborates with one or more of the current Callier faculty. Because the program is funded through Callier’s Excellence in Education Fund Endowment, it provides the Postdocs with a great deal of flexibility in their research endeavors to advance knowledge and excellence in communication sciences and disorders.


Current Post-Docs

Mitchell Frye, AuD, PhD, CCC-A

Mitchell Frye was awarded a PhD in Hearing Science from the State University of New York at Buffalo in 2018. He earned his clinical AuD degree from Wichita State University in 2015 and his BS in anthropology from Kansas State University in 2007. Dr. Frye is a licensed audiologist in the state of Texas, and his research interests span both clinical audiology and auditory neuroscience. His primary research activities have focused on cochlear immunology during postnatal development and aberrant immune states of the inner ear associated with traumatic noise insult, age-related hearing loss, and chronic lower-level noise exposure. His long-term research goals include obtaining a more comprehensive understanding of the cochlea’s immune capacity, activation and resolution—each of which is an important future biological target for reducing and ameliorating inner ear damage.

Kimberly C. Jenkins, PhD, CCC-SLP

Kimberly Jenkins earned her Ph.D. in Speech and Hearing Sciences from Indiana University Bloomington in 2018 under the mentorship of Dr. Raquel Anderson. She received her M.S. and B.S. in Speech and Hearing Sciences from the University of North Carolina at Chapel Hill. Her general research interest is the development of grammar and its relationship to cognitive processes (e.g., executive functions) in typically- and atypically-developing child dual language learners (DLLs), with specific focus on children acquiring Spanish and English. Additional research interests include the assessment and treatment of language disorders in culturally and linguistically diverse populations. Her current research examines the association between home language experience, cognitive ability and second language grammatical skill in sequential DLLs. The goal of her work is to increase our knowledge of the diverse language profiles of DLLs, inform theoretical perspectives with respect to dual-language learning and determine the most efficacious treatment approaches to facilitate language learning in DLLs with language disorders.

Meghan Davidson

Meghan M. Davidson, PhD

Meghan Davidson earned her PhD in 2016 in Communication Sciences and Disorders from the University of Wisconsin-Madison under the mentorship of Dr. Susan Ellis Weismer. She received her clinical MS in speech-language pathology from the University of Wisconsin-Madison in 2011, and she worked as a speech-language pathologist at the Communication Development Center for five years. Dr. Davidson received her BS from the University of Arizona in 2004.

Dr. Davidson's research focuses on language, literacy and cognition in children with autism spectrum disorder (ASD). Her specific research interests are in the contributions of different cognitive and linguistic factors in the development of reading abilities across the autism spectrum. She employs eye tracking technology to measure reading, particularly comprehension, in order to examine specific reading processes in this population. The goal of her work in this area is to determine areas of strength and weakness in reading abilities and underlying skills in order to identify targeted areas for effective clinical treatment.


Patrick Reidy

Patrick Reidy, PhD

Patrick Reidy earned his PhD in Linguistics from The Ohio State University in 2015 under the mentorship of Dr. Mary Beckman. He then trained with Dr. Jan Edwards at the Waisman Center at the University of Wisconsin-Madison. His research focuses on the development of speech production skills in children with normal hearing and in prelingually deaf children who have received a cochlear implant. In particular, his work seeks to better understand the relationship between speech development and hearing ability. During his time at the Callier Center, he intends to extend his research program into articulometric studies of children's productions of consonant-vowel sequences and perceptual studies of how children weight various acoustic cues to consonant contrasts.

Areas of interest: Speech development, speech motor control, coarticulation, hearing impairment, cochlear implants.
