  • Research Interests

    Dr. Sun's research has been in modeling, parameter estimation, algorithm development, and performance analysis for various human-designed and biomedical systems by means of signal processing, image processing, probability and statistics, and information theory. These include development of a family of local maximum likelihood detectors for image reconstruction and wireless communications, a local maximum mean approach to detection of microvessels from magnetic resonance angiography image, an approach for robotic to search sources, a biomarkers spectral subspace approach to cancer detection through tissue fluorescence, power spectral analysis of pulse train over random time scaling, and an approach to neovascularization assessment of tumor and atherosclerosis by DCE-MRI, as well as development of a number of algorithms and methods for image restoration, pattern recognition, artificial neural network, signal detection, power spectrum analysis, biomedical data analysis, wireless communication and networking. 
        Dr. Sun's research interests are recently focused on stochastic optical localization nanoscopy for superresolution single molecular imaging, including algorithm development to enhance the spatiotemporal resolution, establishment of information-theoretical foundation for the spatiotemporal resolution, and quantitative analysis of nanoscale structure and dynamics of biological samples.
