Dr. Tudorascu’s research focuses on improving brain tissue classification in presence of white matter lesions and atrophy in neuroimaging studies of people with age-related pathology or Alzheimer’s disease. She is also interested in developing methods for data harmonization for multi scanner, multi center neuroimaging studies. She is currently principal investigator of a National Institute on Aging-funded R01 grant focused on statistical methods to improve reproducibility and reduce technical variability in multimodal imaging studies of Alzheimer’s disease.
Dr. Tudorascu collaborates widely with colleagues in psychiatry, biostatistics, neurology, radiology, among many other departments at Pitt as well as outside institutions. Dr. Tudorascu’s activities include training others in statistical methods used in multimodal imaging studies of neuropsychiatric disorders.
