Autism Spectrum Disorder

What we do


Our research explores the changes related to age and gender in older adults with autism, focusing on both strengths and vulnerabilities. Additionally, we extend behavioral interventions to address challenges such as depression, anxiety, quality of life and social communication issues for individuals across different age groups. The team places a strong emphasis on education and training, offering learning opportunities for both undergraduate and graduate students in various programs with clinical training for students studying speech-language pathology. We collaborate with the Employment Assistance and Social Engagement program (EASE) and participate in the Interdisciplinary Multicultural Professional Autism Clinical Training (IMPACT) training grant. This grant is led by Drs. Rotheram-Fuller and Scherer, to provide specialized education and clinical experiences for students in speech-language pathology and special education with an emphasis on autism spectrum disorder and is funded by the U.S. Department of Education Office of Special Education.
