Serguei Pakhomov, PhD
My research interests include evaluating and developing novel computational approaches to natural speech and language processing in the medical domain, including text of medical records and language produced by patients during cognitive testing. I study spontaneous speech and language characteristics indicative of effects of medications and neurodegenerative disorders on human cognition, and work on developing natural language processing and machine learning techniques to extract information from text of clinical reports and biomedical literature.
