Professional & Research Experience

• Developing a new imaging system referred to as Parameterized Computational Imaging (PCI) that takes a limit set of measured parameters to update a high resolution baseline image using multiphysics computational models that contain time varying parameters. The technique takes advantage of automatic image segmentation algorithms, Wireless Body Area Networks (WBAN), sensor fusion, and other technological advances to provide continuous, portable, and remote imaging.
• Develop Finite Element Method (FEM) models of the interaction of tissue and electric current/lasers using COMSOL Multiphysics software.
• Explore the interaction of electric properties of tissue with temperature, tissue damage, blood flow, structure, and other dynamic properties.
• Developing COMSOL model for analyzing AC current interaction with tissue.
• Developed COMSOL/MATLAB/LABVIEW code for laser/skin interaction.
• Automated DOS based Monte Carlo code for photon migration analysis.
• Enhance IR tracker algorithms using Matlab and C.
• Developed programs in LABVIEW and C.
• Developed driver in C for VME based GPIB board on Sun Solaris OS.
• Simulated laser and optical systems using MATLAB and C.
• Programmed high power laser propagation through the atmosphere.
• Simulations included adaptive optics that improved beam quality.
