Courses Include: • BME 551L: Biomedical Optics, Spectroscopy and Tissue Optics, Duke University. • BME 303: Modern Diagnostic Imaging Systems, Duke University. Junior level course covering multiple imaging systems including ultrasound imaging, X-ray radiography, computerized tomography (CT) and magnetic resonance imaging (MRI).

Specialization in optical design and instrumentation, medical device design, image processing, and machine learning. Projects include: • In vivo detection of esophageal dysplasia using angle-resolved low-coherence interferometry light scattering with optical coherence tomography (OCT) image guidance. • Automated cervical dysplasia classification using depth-resolved angular scattering measurements based on convolutional neural network. • Computational reconstruction of angular scattering distribution through a single multimode fiber. • Evaluation of diagnostic impact for angle-resolved low-coherence interferometry (a/LCI) and its implications for a/LCI probe designs.

Graduate Researcher

• Cooperated with other graduate researchers on designing and building a combined angle-resolved photoemission spectroscopy (ARPES) and molecular beam epitaxy (MBE) system to map the electronic band structure and Fermi surfaces

• Developed and implemented a novel 3D Fourier iterative reconstruction algorithms for high-resolution 3D imaging using Matlab • Constructed and calibrated 3D imaging phantoms for gamma-ray imaging • Developed and implemented novel image-quality-enhancement algorithms to reduce "bad pixels" and improve 3D image quality

• Designed and nanofabricated a six-terminal electronic-transport measurement microchannel using ultraviolet lithography • Fabricated ultrathin FeSe films using ultrahigh vacuum low-temperature molecular beam epitaxy (MBE)
