- Brain 1H spectrum (single voxel in the basal ganglia) at 3T fitted in LCModel using phantom basis spectra and water signal as an internal reference. Note that tight Cramer-Rao lower uncertainty bounds on detected brain metabolites (table, in blue font) provide opportunity to study subtle brain changes in neuro-degenerative or psychiatric conditions.
- Breast 1H spectrum (single voxel in fibroadipose tissue) at 7T fitted in LCModel using simulated lipid signals. Reliable and precise quantification of fat signals here is of significant importance for studies of possible correlations between fat composition and cancer risk.

Research Overview
I am involved in developmental efforts in high field MRI and MRS (1H, 13C, 31P) with applications for breast and brain cancer imaging.
I am also interested in multimodal imaging and quantitative MR spectroscopy of neurodegenerative disorders.
