My research interests include spatio-temporal modeling, multiple testing problems, and their applications to imaging data, in particular, fMRI images. I am also interested in multi-modal imaging data analysis, e.g., fMRI and DTI.
My current research focuses on investigating the effect of insulin detemir on longitudinal changes in reward circuitry and resting-state functional connectivity of the brain by using spatio-temporal models and the Likelihood Paradigm which is known to better control Type I and II error rates.
