    Dr. Olga Tymofiyeva is an Assistant Professional Researcher in the UCSF Department of Radiology and Biomedical Imaging, where she is establishing her independent research program titled “BrainChange” by conducting an innovative NIH-funded neuroimaging study of brain plasticity in adolescents with training of attention and emotion regulation. In her research, Dr. Olga Tymofiyeva utilizes the cutting-edge approach of MRI connectomics, which allows for the noninvasive examination of brain networks.
