Chunyu Qiao

Experience

Chunyu “Joe” Qiao joined WJE in 2021, bringing his academic and industry expertise analyzing building material quality and durability. He has consulted on numerous materials problems, integrating petrographic, chemical, and electrical techniques. His experience covers a wide range of topics, including concrete quality control, surface defects, durability, early-age shrinkage, supplemental cementitious materials, chemical admixtures, and service life modeling. Dr. Qiao is skilled in visualizing and quantifying his investigation findings using multiple state-of-the-art methods, such as fluorescence microscopy, image analysis, and electrical resistivity.

Prior to joining WJE, Dr. Qiao was a visiting scholar at Purdue University and a postdoctoral researcher at Oregon State University. Since his doctoral studies, he has conducted extensive research on concrete microstructure, transport properties, freeze-thaw damage, deicer damage, electrical resistivity and formation factor, service life modeling, and low-carbon footprint construction materials. Dr. Qiao has published more than thirty peer-reviewed journal articles and presented his research at international conferences, including the American Concrete Institute (ACI), the American Ceramic Society (ACerS), and the International Congress on the Chemistry of Cement (ICCC).
