Kia Felder Williams
Kia Felder Williams, M.A., is an ASPIRE Ph.D. scholar in the special education doctoral leadership grant with George Mason University. She has experience as a special educator in the urban school setting of Prince George's County, MD. Kia has instructed elementary students with high-incidence disabilities, primarily autism spectrum disorder, ADHD, and emotional and behavioral disabilities. Her major research interests center around the disproportionality of Black/African Americans in special education and include the perception of dis/ability diagnoses of parents, children, and families and the impact on care, treatment, and intervention. Kia views the intersectionality of race, culture, and education through a critical lens and she leans towards a dis/ability critical race framework to define, interpret and explore research questions. Kia has two peer-reviewed publications on using a culturally responsive lens to revise a core preparation course and cultural humility and Universal Design for Learning as disrupters for disproportional placement of students of color in special education. She has presented at two national and three local and state conferences, shared as a guest lecturer in two higher education courses, and has written the chapter: Understanding Racial Differences in Diagnosis of BIPOC Children in a special report entitled Understanding Experiences of BIPOC Children and Adults with ADHD: Prevalence, Perspectives, and Access, for the national organization CHAAD (Children and Adults with Attention-Deficit/Hyperactivity Disorder). Kia is currently working on a research project analyzing family perceptions of diagnosis, barriers to treatment, and racialized attitudes toward the behavior of BIPOC children with ADHD diagnoses, and she is co-writing an article regarding family engagement and cultural reciprocity. Finally, Kia is an Officer on the Executive Board of the PhD in Education Student Organization (PESO) at GMU for the 2022-23 school year.
