Dr. Hao Gao is a Professor of Biomedical Engineering. He is also a Professor of SJTU Department of Mathematics. He was an Assistant Professor in Departments of Mathematics & Computer Science, Radiology & Imaging Sciences of Emory University, an Assistant Professor (Ph.D. program faculty) in Department of Biomedical Engineering of Georgia Tech/Emory University, and a recipient of NIH R21 Exploratory/Developmental Research Grant Award, 1000 Young Talents Plan Award and Qiu Shi Outstanding Young Scholars Award. One of his major research directions is on the fast multiscale algorithms and high-performance parallel computing for radiative transfer equation and its inverse problems, such as diffuse optical tomography, fluorescence tomography, bioluminescence tomography, quantitative photoacoustic tomography, multi-modal optical imaging, and computational radiotherapy. Another major research direction is the effective compressive sensing models, sparse Fourier transform, and fast optimization algorithms for medical imaging, such as four-dimensional cone-beam CT, spectral CT, helical CT, and diffusion-weighted MRI.
