Short Bio

Charalambos (Haris) K. Themistocleous, a Professor of Speech, Language, and Communication at the University of Oslo, holds a Ph.D. in Linguistics from the University of Athens and conducted postdoctoral research at Johns Hopkins University and the University of Gothenburg.

His research focuses on using AI methods, including machine learning and natural language processing, to quantify the effects of brain damage on speech and language. He develops models for the early diagnosis and prognosis of conditions like aphasia, dementia, and mild cognitive impairment by integrating linguistic analysis with multimodal data.

Dr. Themistocleous leads the development of Open Brain AI, a computational platform that automates speech and language analysis for clinicians, researchers, and educators. He has also developed widely adopted digital tools for assessing spelling, phonology, and semantics.
