-Helped to Integrate ICE transducer into new imaging ultrasound platform. -Software engineered an generalized signal processing path in C++/CUDA (GPU) for new imaging system. Brought up B-mode signal path for prototype. -Researched new imaging algorithms and technologies

I provide sustaining support and perform feature development for high-end ultrasound imaging systems. My primary responsibilities in this job have primary areas have been: • Ultrasound system image optimization • Software development and debugging • Research and development of new system features

As a post-doctorate research associate in the department of medical physics I worked with Tim Hall and team in advancing the studies of ultrasound research projects including: • Quantitative ultrasound (QUS) imaging, which is the imaging of estimated model (or acoustic) parameters from collected ultrasound data. • Tissue strain elastography • synthetic aperture beamformation • Compressed sensing and other undersampling techniques • Kalman-filter based speckle tracking models.

As a PhD candidate/research assistant in the ultrasound research laboratory, I worked and studied with Robert Waag and lab associates in the areas of: • Ultrasound tomography • Analytic modeling and computation of acoustic scattering from 2- and 3-D objects • Accelerated analytic computation of acoustic scattering (Fast multipole methods) • Aberration correction methods • Computational acoustics (primarily with Finite difference time-domain methods)

During my tenure as a research assistant in the BYU microwave earth remote sensing laboratory, I worked with David Long and associates in the areas of: • Synthetic aperture radar (SAR) imaging (beamforming) algorithms • SAR motion compensation • Autofocusing algorithms • Radar interferometry image processing • Radar system design

Ph.D. Dissertation title: The Use Focused Beams with Unique Biomedical Ultrasonic Imaging Systems

Master's degree specialization: Medical Imaging Graduate Coursework highlights: • Medical and ultrasound imaging • Stochastic/Random processes • Digital signal and image processing • Fourier optics

Master's thesis title: Motion Compensation of Interferometric Synthetic Aperture Radar Graduate Coursework Highlights: • Advanced electromagnetics • Computational electromagnetics • Microwave earth remote sensing • Radar systems design • Advanced signal processing (signal modeling, adaptive filtering, power spectrum estimation) Undergraduate Senior Project: : 2-player, miniaturized autonomous robot soccer (placed 1st out of 10 teams). Skills learned/applied: Kalman filtering (tracking), computer vision techniques, sensors, non-linear system modeling and control theory.
