Matthew received a B.A. in History from the University of Arizona in 2001. While obtaining this degree, he discovered and was inspired by behavior analysis and began working with children and adults with disabilities. He spent several years teaching at public elementary and junior high schools in Kumamoto, Japan via the Japan Exchange and Teaching (JET) Programme. He received his M.A. and Ph.D. in Psychology under Dr. Linda Hayes at the University of Nevada, Reno (UNR). During this time, he worked in the UNR Early Childhood Autism Program under Dr. Patrick Ghezzi and as a didactic course and practicum instructor for the UNR Satellite Programs in Behavior Analysis. He held postdoctoral positions conducting scent detection research with the non-profit organization APOPO in Tanzania and in UNR’s Animal Behavior Laboratory (ABL) under Dr. Linda Hayes.
Matthew’s primary interests in the basic and conceptual domains are related to studying the role of motivation and emotion in learning and how individuals’ physiological characteristics interact with their environments to determine their psychological characteristics. Basic research along these lines is conducted in the ABL, for which he is a co-principal investigator and faculty advisor. Some of this research includes interdisciplinary collaborations with researchers outside of behavior science.
In addition to his basic/conceptual interests, Matthew is a Board Certified Behavior Analyst and serves as the faculty advisor for service contracts with Washoe County School District, NV Rural Regional Center, and NV Sierra Regional Center. His research interests in the clinical domain include treatment integrity, observing as a repertoire of behavior, and the maintenance and generalization of skills following behavioral treatment.
