Andresa De Souza, Ph.D.

Dr. Andresa De Souza is an Assistant Professor of Special Education and the ABA Graduate Program Director. She worked under the supervision of Dr. Ruth Anne Rehfeldt during her Master's and participated in various projects involving Skinner's verbal behavior and the emergence of verbal operants. During her Doctoral degree, she conducted a study to evaluate the emergence of complex intraverbals for children with autism under the guidance of Dr. Wayne Fisher. During the course of her studies, Dr. De Souza gained valuable experience in early-intervention applications for children with autism, the assessment and treatment of severe problem behavior, and autism diagnosis. She has provided supervision for behavior analysts and worked as a consultant for international sites. 

Dr. De Souza has presented in conferences both in the USA and internationally. Currently, she specializes in early intervention for children with autism and parent training. She is also interested in the international dissemination of applied behavior analysis. Dr. De Souza is a Board Certified Behavior Analyst at the doctoral level (BCBA-D) and a Licensed Behavior Analyst at the State of Missouri.
