Prabir Kolay serves as a Professor and Director of Geotechnical Engineering in the Department of Civil Engineering at Southern Illinois University's College of Engineering. With extensive experience in both academia and research, he teaches courses including Soil Mechanics, Civil Engineering Materials, Foundation Design, and Advanced Soil Testing.
- Ph.D. from Indian Institute of Technology (IIT), Bombay (2001)
- M.Eng. from Bengal Engineering and Science University (BESU), Shibpur (1996)
- B.Eng. from North Bengal University (NBU), India (1993)
Dr. Kolay's research focuses on geotechnical engineering with emphasis on soil stabilization techniques, recycled construction materials, and geoenvironmental applications. His work spans soft and expansive soil stabilization using chemical additives, characterization of coal combustion byproducts like Pulverized Fuel Ash, and development of sustainable construction materials using recycled concrete aggregates. He has made significant contributions to understanding the thermal and electrical properties of soils, liquefaction potential of local Illinois soils, and cyclic behavior of stabilized soils, advancing both theoretical knowledge and practical applications in the field.
His recent publications (2016-2020) demonstrate a strong focus on sustainable geotechnical solutions, with particular emphasis on soil stabilization using alternative materials, recycled construction aggregates, and fiber reinforcement techniques. The research spans fundamental soil mechanics investigations to practical applications in infrastructure development, with growing attention to environmental considerations in geotechnical engineering.
