Dr. Chavez's research focuses on extracting quantitative physical biological information from complex MR signals. Her areas of interest include relaxometry (T1 T2 mapping), brain function (functional MRI, fMRI), brain microstructure (diffusion tensor imaging, DTI), brain chemistry (spectroscopy, MRS), and cerebral blood flow (arterial spin labeling, ASL). The research aims to develop robust methods to obtain accurate, tissue-specific MR measures, along with new methodologies for data sampling and signal processing. Furthermore, she has developed new algorithms for detection and correction of image artifacts (e.g., phase unwrapping and spike noise) and field mapping (B1), all aimed at improving data quality and overcoming imperfections associated with the measurement process. Dr. Chavez's research goal is to improve the capability of MR to yield quantitative, tissue-specific measures with a specific focus on psychiatric disorders. Her work will aid in the discovery of new biomarkers for monitoring disease progression and treatment response.
