The CSD Doctoral Cohort

The Communicative Sciences & Disorders Department is currently home to 14 doctoral students, all with varying interests and focuses. Below is a little about them, and their interests within CSD:

Meisam Arjmandi Meisam Arjmandi.jpg

Meisam Arjmandi began his Ph.D. in the Department of Communicative Sciences and Disorders at Michigan State University in the fall of 2015. He received his B.Sc. and M.Sc. in Electrical and Biomedical Engineering, focusing on objective assessment of voice disorders. Meisam is currently doing research in MSU Speech Perception and Production Lab, working in three main areas: (1) Neurocognitive and behavioral mechanisms underlying perception of non-standard speech, (2) The role of prosodic cues on spoken word recognition in continuous natural speech, and (3) Infant-directed speech and language development in infants with hearing loss.

Meisam's long-term goal is to unravel the mechanism underlying the effective and robust sensation, perception, and recognition of audio-visual speech cues during oral communication. To this end, he aims to utilize various behavioral, signal processing, and neuroimaging techniques to elaborate our understanding of this multifaceted system of speech and language production/comprehension. The findings will pave way for devising more effective methods/tools for assessment, prevention, and treatment of disorders of speech and language. 

Meisam was recently awarded two Charles J. Strosacker Research Funds to identify acoustic phonetic properties of speech of African Americans and individuals with neurological disease (e.g. Parkinson's disease and traumatic brain injury (TBI)). 

Key Research Interests:

  • Neurocognitive & Acoustic Basis of Speech Perception and Production
  • Objective & Subjective Assessment of Voice Disorders
  • Cognitive Neuroscience of Speech & Language Disorders
  • Biomedical Signal Processing & Pattern Recognition
  • The Role of Prosody in Perception of Normal & Dispordered Speech
  • Infant-directed Speech & Language Development in Infants

Russell Banks, M.A., CCC-SLP

Russell Banks began his PhD at Michigan State University in the Fall of 2016. He is currently studying brain injury and the effects of concussion on the voice. He has presented his research recently at the International Brain Injury Association conference in New Orleans. He has also been in collaboration with Notre Dame University to further this research.  Russ was awarded the Strosacker Fellowship in January 2016. 

Russ completed his Master’s Degree in 2015 under Dr. Hunter’s mentorship in the Department of Communicative Sciences and Disorders at Michigan State University and completed his CCC’s in 2016. Russell Banks_0.jpgFor his thesis, he surveyed teachers in school districts across the United States to determine the effect on the voice by: (1) the size of each teacher’s classroom, (2) the vocally demanding extracurricular activities performed by each teacher, and (3) any habits that teachers may have. This research has been presented at several conferences and is currently being written up for publication. 

Before coming to MSU, Russ was mentored by Dr. Hunter at the National Center for Voice and Speech in Salt Lake City, Utah—a center at the University of Utah, where he graduated with a Bachelor of Science from the Department of Speech and Hearing Sciences. There he was involved in several voice research projects. These research projects involved voice therapy techniques for singers and occupational users of voice, aging voice, and voice perception. Russ has worked with several voice and acoustical analysis software programs including Audacity, ADSV, LABChart, WaveSurfer, ELAN, TF32, Elan, Praat, various KayPentax programs, etc. Russ also worked with another student at the University of Utah on software that quantified recovery in rehabilitation of various voice disorders.

Mark Berardi Mark Berardi.jpg

Mark Berardi is a Ph.D. Student in the Department of Communicative Sciences & Disorders and primarily works with Dr. Eric Hunter. He is a dual Ph.D. major in the Department of Computational Mathematics, Science, and Engineering. Before coming to MSU, he received his B.S. in Applied Physics and worked with the Acoustics Research Group at Brigham Young University. His main research focus was the quantification of changes in vocal effort to varying acoustic environments. At MSU, Mark works on cutting edge machine learning applications to speech and voice disorders. Other professional interests include musical acoustics, architectural acoustics, and audio engineering.

David Ford, M.S., CCC-SLP David Ford.jpg

Prior to beginning the Ph.D. program, David spent 5 years treating patients with voice & swallowing disorders at Straka & McQuone, Inc., a private otolaryngology practice located just outside of Pittsburgh, PA. He also enjoyed appointments as adjunct professor and clinical instructor at Duquesne University. 

David received his Master of Science degree in Speech-Language Pathology from Duquesne University and has had clinical experience at HealthSouth Rehabilitation Hospital and Ohio Valley General Hospital. He completed his clinical fellowship at the Northwest Clinic for Voice & Swallowing at Oregon Health & Sciences University (OHSU). During his clinical fellowship, David had the opportunity to complete research investigating functional communication improvement following Lee Silverman Voice Treatment. His current research interests include: voice physiology, professional voice users, and vocal pathology. David has been featured in the ASHA Leader, a national publication celebrating excellence in speech-language pathology; the Liturgical Singer; and on the KDKA 6 O'Clock News.  He formerly served as the Vice President of Membership & Ethical Practices on the Pennsylvania Speech Hearing Association (PSHA) executive board of directors.

Hamzeh Ghasemzadeh Hamzeh Ghasemzadeh.jpg

Hamzeh Ghasemzadeh was born in Tehran in 1984. He received both his BS and MS in Telecommunications Engineering. He was an adjunct professor at department of Electrical Engineering at Islamic Azad University, Damavand Branch until 2016. He is now pursuing a dual Ph.D. degree in both “Communication Sciences and Disorders” and “Computational Mathematics Science and Engineering” at Michigan State University. He has been working on different aspects of audio signals, covering acoustic analysis of pathological impaired voices to security driven applications of audio signals. His primary research interests are applying statistical signal analysis and machine learning techniques for solving different speech/voice related problems. Right now, he is working on statistical signal processing and data mining of data acquired through high speed videoendoscopy (HSV) from vocal folds.
