Dr. Joshua Ramirez earned his Ph.D. from U.C. Irvine’s Cognitive Sciences doctoral program. He also received his M.A. in Social Sciences and B.A. in Psychology from U.C. Irvine, as well. Dr. Ramirez's graduate work examined the psycholinguistic, developmental, and neurological basis of reading disabilities. For five years, he served as a pre-doctoral research fellow for the National Institutes of Health’s (NIH) National Institute for Child Health and Human Development.

Dr. Ramirez's primary academic interests include speech perception, language acquisition, development, comparative anatomy and physiology, and visual intelligence. He also has an interest in studying modern Western European history. Dr. Ramirez previously taught at U.C. Irvine as an instructor of record, teaching associate and laboratory instructor. He joined the SOCCCD in 2009 and proudly teaches concurrently at Irvine Valley College and Saddleback College as associate faculty.

NIH Pre-Doctoral Research Fellow and Ph.D. Candidate (Spring 2004 to Spring 2009): Conducted synthetic speech perception experiments and psychophysical testing of visual magnocellular function with dyslexic and typically reading elementary school students; assessed reading achievement, non-verbal intelligence, audiometric, and visual contrast sensitivity profiles.

Lead Researcher, Interdepartmental Research Unit (Summer 2001 to Winter 2002), UCI Department of Cognitive Sciences and Department of Otolaryngology: Examined dissociations in the speech perception pathologies associated with auditory neuropathy and developmental dyslexia under the direction of Dr. Virginia Mann and Dr. Fan-Gang Zheng.

Undergraduate Understudy (Summer 1998 to Summer 1999): Examined cerebral hemispheric asymmetries in processing speech sounds as a member of the UCI Center for Language and Brain Research.


In his spare time, Dr. Ramirez enjoys learning about wildlife and conservation efforts. Whenever work permits, he enjoys taking weekend trips to California’s great national parks and world famous zoos. He also enjoys recreational photography, gardening, and landscaping.
