Judah Axe

Associate Professor

Education

PhD in Special Education and Applied Behavior Analysis, Ohio State University
MA, Ohio State University
BS in Biology, University of Wisconsin-Madison

Judah Axe started teaching at Simmons in the fall of 2008, after working with children with autism and other disabilities and attending graduate school at Ohio State University. He now teaches courses in his passion areas, including applied behavior analysis, the analysis of verbal behavior, single subject research design, and assessment of challenging behavior.

Axe’s research focuses on evaluating techniques for teaching students with autism and related disabilities in the areas of communication, social skills, and reducing challenging behavior. In the area of communication, he is evaluating prompting and prompt fading techniques for teaching language skills to children with disabilities. In the area of social skills, Axe found that video modeling and tactile prompts are effective in increasing eye contact and responses to facial expressions with children with autism, and he is currently studying procedures for establishing social attention as a reinforcer. In the area of challenging behavior, he is conducting studies on antecedent manipulations for reducing escape-maintained problem behavior with students with severe disabilities.

In addition to teaching and research, Axe is active in professional organizations serving behavior analysts. He serves in two positions within the Association for Behavior Analysis International: chair of the Verbal Behavior Special Interest Group and co-coordinator for the verbal behavior area of the annual convention program. He serves as the Student Relations Committee chair of the Berkshire Association for Behavior Analysis and Therapy, as well as a trustee and the continuing education coordinator of the Cambridge Center for Behavioral Studies. He also serves on the editorial boards of The Analysis of Verbal Behavior and the International Journal of Behavior Analysis and Autism Spectrum Disorders, and as a guest reviewer for other journals.

When he is not working, Axe enjoys walking along the Charles River with his wife and baby girl.

PhD in Behavior Analysis, Simmons University
MS in Applied Behavior Analysis, Northeastern University
BS in Psychology and Spanish, University of Nevada, Reno

Gretchen A. Dittrich is a Licensed Applied Behavior Analyst (LABA) in the state of Massachusetts and a doctoral-level Board Certified Behavior Analyst® (BCBA-D®). She is an associate professor of practice and the director of mentoring and supervision in the Department of Behavior Analysis at Simmons University. Dittrich has a private practice dedicated to providing services to improve behavioral, academic, social, communication, health, vocational, and independent-living skills in people with special needs. She provides consultation, training, and workshops to parents, caregivers, educators, and specialized educational institutions on reducing problem behavior, increasing communication, alternative and augmentative communication methods, and behavior analysis. In addition, she has published and presented research nationally, focusing on reducing challenging behaviors, increasing social skills, and health promotion.

Dittrich has been working with individuals, families, and school systems since 1998, helping clients improve skill deficits and reduce unwanted or challenging behavior. While her work has focused on helping individuals with intellectual and developmental disabilities, she has also worked with individuals who have behavioral challenges, social skill deficits, and health concerns (e.g., overweight, obesity, inactivity). Dittrich’s research interests include behavioral medicine and health promotion (including the prevention and amelioration of obesity and inactivity), functional analysis of complex behaviors, social skill training, the application of behavior analytic methodologies to higher education, and verbal behavior. She is the current chair of the Behavioral Medicine Special Interest Group of the Association for Behavior Analysis International (ABAI).

Christina King

Adjunct Faculty

Christina King graduated from Boston University in 2003 with a degree in communication disorders. After working with a child who had autism during her undergraduate program, King decided to change her career goal from becoming a speech language pathologist to working in the field of applied behavior analysis. Upon graduating from BU, she enrolled in the Simmons University Behavioral Analysis master’s program and earned her BCBA certification in 2004. King currently serves as the director of RCS Learning Center and is a doctoral student in the Behavior Analysis program at Simmons University where she is conducting a stimulus equivalence analysis of the emergence of novel forms of language.

Through her research, King hopes to explain how novel language develops and is displayed by the participants; she ultimately plans to use this methodology to improve the effectiveness and efficiency of language training for children with autism and other language-based developmental disabilities.

King has presented at multiple conferences, including the Association for Behavior Analysis International (ABAI), Simmons University Contemporary Developments in Behavior Analysis, the Massachusetts Association of Behavior Analysis (MASSABA), the Berkshire Association of Behavior Analysis and Therapy (BABAT), and the Massachusetts Association of Approved Private Schools (MAAPS).
