Research Interests

Dr. Peter Richtsmeier is an expert in the areas of speech development and speech sound disorders. His research career began in the field of linguistics. He studied typical phonological development at the University of Arizona under Drs. LouAnn Gerken and Diane Ohala, and he defended his dissertation in 2008. After completing a postdoctoral fellowship with Dr. Lisa Goffman at Purdue University, Dr. Richtsmeier transitioned to speech-language pathology in order to better understand child speech and language disorders. He completed his clinical master’s degree at Purdue in 2014. At Oklahoma State, Dr. Richtsmeier teaches courses on developmental speech and language disorders. He also directs the Phon Farm research laboratory where he and his students conduct experiments on child speech development.
