Lisa Erwin-Davidson, Ph.D., CCC-SLP

Lisa Erwin-Davidson, Ph.D., CCC-SLP is a researcher, educator, SLP, and AAC Visionary. She is Assistant Professor in Communication Sciences & Disorders at  California State University-Fullerton. Her core beliefs about teaching include: (1) Teaching is critical, not only to my own scholarly activities, but central to future generations of speech-language pathologists. (2) Bridging research and practice is for the ultimate benefit of our clients/students/patients. (3) Through shared and respectful interactions, a truly civil society can prosper. This is realized through respectful discourse with peers and students at every level of inquiry and within an environment that fosters creativity and independent thought.
