My background straddles the fields of computational imaging, image science, image processing and analysis, and machine learning. My research work has leveraged the interconnections between these fields to develop optical and computational imaging modalities, mathematical models of image formation, image understanding, and image transforms applied to diverse areas such as predicting cancer progression and risk stratification, characterizing nanoscale nuclear morphology during cell proliferation and chromatin decondensation, situational awareness applications, temporal compressive imaging, optical coherence tomography, color science, computer-aided diagnostics, diffraction tomography, and pathology informatics.
More recently, my research work has expanded to studying computational biophysics, spatial heterogeneity in tumor microenvironment, and graphical models. I will be adding details soon.
Paper on depth-resolved nanoscale nuclear architecture mapping for cancer detection – based on Fourier phase associated with Fourier-domain optical coherence
tomography – has been published in Methods, Elsevier. The paper details the principle, theory, modeling, simulation, instrumentation, and application of our method.
