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. The accomplishment includes development of a family of modified Hopfield neural networks, 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 networks, signal detection, power spectrum analysis, biomedical data analysis, wireless communication and networking. 

    Dr. Sun's recent research interests are in the field of stochastic optical localization nanoscopy for superresolution single molecular imaging, including establishment of information-theoretical foundation of spatiotemporal resolution, development of localization algorithms to enhance spatiotemporal resolution, and quantitative analysis of nanoscale ultrastructure and dynamics of biological samples. Dr. Sun's research interests also include modeling of intimate relationships.
