My current research interests are focused on the development of statistical methods for high dimensional data analysis. High dimensional data problems arise in various fields such as functional neuroimaging, DNA and metagenomic microbial communities sequencing. I worked on fMRI voxel-wise connectivity analysis problems using wavelet shrinkage denoising methods and large covariance matrix estimation for dependent data. My current research projects involve algorithmic and eigen-decomposition based dimension reduction techniques for next generation microbiome sequencing data visualization and health outcomes prediction. I also work on evaluating the effect of data pre-processing bias on statistical analysis.
I collaborate with microbiologists, statisticians and mathematicians to achieve both biologically relevant and mathematically justified solutions to these interdisciplinary problems. As a part of our work, we provide software solution and data analysis methods manuals to our collaborators working in clinical and translational research.
