Research
01 Ultrasonic B-Mode Imaging
This is my most recent ultrasonic research on medical imaging working as a senior ultrasound system engineer at eSonic Image.
​
The main research focuses on beamforming algorithm development and its verification for B-mode imaging (i.e., impedance imaging) on a cart-based ultrasound system.
The right figure shows an example of a beamformed image from a curved array probe.
02 Ultrasonic Borehole Imaging
This is my ultrasonic research on borehole imaging while working as a senior acoustic research scientist at Halliburton.
​
The main work duties include pulse-echo mode signal measurement, arrival time extraction, borehole geometry estimation, acoustic impedance imaging, and image correction on a logging-while-drilling tool aimed at oilfield exploration.
The left figure shows a drilling tool equipped with four transducers positioned 90 degrees apart from each other. Additionally, 2D and 3D images depicting borehole radius and borehole impedance are presented.
03 Ultrasonic Shear Wave Scattering Characterization & Quantification
This is my ultrasonic research on quantitative non-destructive evaluation while working as a graduate research assistant at the Georgia Institute of Technology.
​
My Ph.D. research mainly focuses on shear wave scattering characterization and quantification from various defects in aluminum plates, aimed to mimic actual ultrasonic defects in the aerospace industry.
​
The right figure shows an example of through-hole scattering characterization and quantification in the time-space domain.​
04 Ultrasonic Array Imaging
This is an ultrasonic project on array imaging before my Ph.D. research at the Georgia Institute of Technology.
​
The project considers ultrasonic guided-wave structural health monitoring with sparse transducer arrays to achieve detection and localization of discrete damage.
​
There are two figures on the left side, with the first one showing the specimen of an aluminum plate mounted in the testing machine equipped with six transducers and the second one showing an example of damage localization result based on Rayleigh-maximum-likelihood estimation.
05 Smart Clock
This is a pretty fun class project that integrated electronics and mechanics at the Georgia Institute of Technology.
​
We designed a smart clock, also called Revolutionary Time, which mainly consisted of a flip clock and a spin LED clock (i.e., the persistence of vision display).
​
There are two figures on the right side, with the first one depicting the smart clock without spinning and the second one showing the smart clock with spinning.
