The Speech Disorders & Technology Lab members are with a variety of backgrounds, including computer science, electronic engineering,  communication sciences & disorders, neuroscience, and biomedical engineering.

Primary Investigator

Dr. Jun Wang is the primary
investigator of the UT Dallas Speech Disorders & Technology Lab. Dr. Wang earned his PhD in computer science with a cross training in communication sciences and disorders from the University of Nebraska - Lincoln in December 2011, advised by Drs. Jordan R. Green and Ashok Samal. He was a Software Engineer at IBM China Software Development Lab in Beijing before coming back to graduate school for pursuing his doctoral degree.  Dr. Wang joined UTD Callier Center as a Research Scientist in 2012 and then began his current position in June 2014.



Dr. Anusha Thomas, a visiting scholar in the lab, obtained her PhD in Communication Sciences & Disorders from the University of Nebraska-Lincoln in 2012. Dr. Thomas was a lecturer at the Manipal College of Allied Health Sciences, Manipal University, India before she came to US. She is part of the ALS project in the lab. Her own research focuses on speech motor control in children with CAS. 


Dr. Myungjong Kim is a Postdoctoral Research Associate in the lab. Dr. Kim earned his PhD in Electrical Engineering from Korea Advanced Institute of Science and Technology (KAIST) in February 2016. Since joining the lab in May 2016, Dr. Kim's research has focused on machine learning and signal processing for disordered speech assessment and recognition, silent speech recognition, and brain activity signal analysis.


Beiming Cao,  PhD student in Electrical and Computer Engineering, is a Research Assistant is the lab.  He obtained his Master's degree in Electrical Engineering from Southern Methodist University. His research focuses on speech signal processing with a special interest in silent speech recognition, dysarthric speech recognition, and speech synthesis.


Kristin Teplansky, PhD student in Communication Sciences & Disorders, is a Research Assistant is the lab. She obtained her Bachelor's degree in Speech-Language Pathology and Audiology from UTD Callier Center for Communication Disorders in 2014 and has worked a speech therapist in North Dallas area. Kristin's current focus is speech motor performance decline due to amyotrophic lateral sclerosis (ALS) based on acoustic and kinematic measures.

Debadatta Dash, PhD student in Biomedical Engineering, is a Research Assistant (RA) in the lab. He obtained his Bachelor's degree in Electrical and Electronics Engineering (EEE) from Veer Surendra Sai University of Technology (VSSUT), India in 2014 and has two and half years of industrial experience from Larsen and Toubro (L&T) Ltd. in electrical design and project management. He was a research scholar at Indian Institute of Technology (IIT), Mandi, where he worked on resting state fMRI analysis.  His research focuses on Machine Learning applications for detection and analysis of neurological speech disorders with a special interest in MEG. He is also a Graduate Research Assistant at UT Southwestern Medical Center working with Dr. Ted Mau on computational voice simulation for assisting vocal fold surgery.


KwangHoon An is a Master student in Computer Science at UTD pursuing the Intelligent Systems track degree. His research interest is in machine learning, graphical model and its applications. He is currently in a part of ALS project in the lab and his role involves in applying machine learning in acoustic/articulatory motion data for classification/regression problem.  


Richard (Jun) Wang is a Master student in the Computer Science department at UT Dallas. His research interest is mainly about speech recognition, natural language processing (NLP), and machine learning algorithm. His work focuses on dysarthric speech recognition, and text-to-speech synthesis using deep learning approaches. Richard is also working on sequential pattern learning for infant language development, a project that is led by Dr. Lisa Goffman at the UT Dallas Callier Center for Communication Disorders.



Kevin D. Tran is a Senior Biomedical Engineering undergraduate student at UT Dallas. He is interested in learning about machine learning and its applications in the biomedical field. After an introduction to machine learning in Dr. Wang’s class, Kevin became interested in the ALS project. In the lab, he seeks to contribute to the ALS classification/regression project using machine learning and other data analysis techniques.


Brian T. Tsang is a Biomedical Engineering undergraduate student at UT Austin. He is interested in applications of Computer Science in Biomedical Engineering research. During his free time, Brian is a competitive table tennis player and plays on the UT Austin table tennis team. He was a summer intern in the lab in 2017 and continued to be involved in data processing and analysis in the silent speech project.


Alyssa Shrode is a sophomore in Speech Pathology and Audiology and an Academic Excellence Scholar.  She is interested in gaining experience with speech disorders, as she is aware of the significant connection between speech and hearing and is confident that better understanding speech disorders will help her be more effective as an audiologist in the future. Alyssa is involved in the UTD Baptist Student Ministry and is a Peer-Led Team Learning (PLTL) leader in the UTD Student Success Center. In the lab, Alyssa is involved with data processing for the ALS project.


Bjorn Bleta is a pre-med and freshman in Biology at UT Dallas. She is currently exploring the research opportunities in biomedical sciences and engineering.  She was in the UT Dallas Biomedical Engineering summer camp 2016, where she built a colorimeter and designed a prosthetic arm. In this lab,  Bjorn is assisting the data processing in the ALS project.


Brittany Shrode is a freshman majoring in Speech-Language Pathology. She is interested in gaining insight regarding speech disorders and the impact that they have on the individual. Brittany is involved with the Baptist Student Ministry (BSM). In this lab, Brittany is involved with data processing for the ALS project.
