    Research Description

    Over the past years, Dr. Deng has carried out extensive research in the areas of sensor systems, imaging physics, signal/image processing, biomedical imaging, electromagnetic imaging, applied electromagnetics, mathematical/physical modeling and simulation, pattern recognition and inverse problems. He has been doing interdisciplinary research on both forward and inverse problems for Medicine and Engineering applications, and has been collaborating with professors, medical doctors, researchers, clinical staff, and graduate students from universities and research institutes (Medical Physics, Electrical Engineering, Biomedical Engineering, Radiology and Psychology, etc.), and also from government and private industries.

    Dr. Deng's current research interests include (a) Smart Sensing and Smart Structures, Structural Health Monitoring (SHM); (b) Hybrid or Multi-wave Imaging modality for NDE and Medical Applications; (c) Novel imaging systems and sensors development for defects detection, delineation and quantitative analysis, (d) Image Analysis such as multi-modal image fusion, image and signal processing that involves linear applications, i.e. image enhancement, reconstruction and noise reduction; as well as the non-linear applications such as image segmentation and registration.

    Dr. Deng's Ph.D. thesis was focusing on the non-invasive imaging, e.g. biomedical, electromagnetic applications: Positron Emission Tomography (PET) system simulation; human respiratory motion estimation and correction; and biomedical image/signal processing as well as innovative magneto imaging methods. Besides those major interests, he is also interested in other medical imaging modalities, i.e. Functional Magnetic Resonance Imaging (fMRI) and MRI (a.k.a NMR), X Ray Computed Tomography (CT, a.k.a CAT previously), Ultrasound Imaging (US) and related physics/engineering applications. In the applied electromagnetics and EM imaging fields, Dr. Deng was actively involved in the development of 3-D computational models for both forward and inverse problems in electromagnetic sensors design and systems optimization at the NDE Lab (one of the top NDE groups in the country).

    In the applied electromagnetic field, His major original contributions to forward problems are as follows: (a) developed and improved three-dimensional electromagnetic computational models using both conventional finite element methods (FEM) and the innovative element-free method (a.k.a. meshless method), which implicitly incorporates high-order basis functions and gives more accurate results; (b) imaging system development and hardware implementation for data acquisition using various methods including eddy current, giant magneto-resistive, magneto-optic and ultrasound. His major original contributions to electromagnetic inverse problems are as follows: automated electromagnetic (conventional eddy current, magneto-optic, and giant magneto-resistive) data interpretation and analysis to classify defective/defect-free signals and prediction of defect size and location (defect reconstruction).

    In biomedical forward and inverse problems, He was focusing on developing statistical biomedical system models, multimodality image fusion, emission tomography image reconstruction, quality enhancement by reducing motion artifacts.

    Dr. Deng is the co-recipient of the Federal Aviation Administration Better Way Award in 2005. Dr. Deng is a full member of Sigma Xi, the Scientific Research Society and a senior member of IEEE. He serves as referees of several scientific journals and international conferences.
