Brief Biography

Junxing Zheng is an assistant professor of geotechnical/materials engineering. He explores fundamentals of particulate materials using advanced computer vision, machine learning, programming, sensor technologies and numerical/physical modeling. Zheng developed computational geometry techniques for material particle shape analysis and rotational haar wavelet transform for material fabric analysis. Those techniques have been used by many researchers in various disciplines. He also has four year industrial experience as a geotechnical engineer prior to attending the University of Michigan.
