Biography

Dr. Chuma Nnaji is an assistant professor in the department of civil, construction, and environmental engineering.

Nnaji holds a bachelor’s degree in building from Imo State University, Nigeria, an MBA from Oregon State University’s College of Business and an master’s and doctorate degree in civil engineering from the School of Civil and Construction Engineering at Oregon State University.

His research focus is on formulating strategies and developing decision support tools that enhance construction safety and health, sustainable construction, human-machine interactions, construction automation, workforce development in different construction environments. Specifically, Nnaji leverages computational tools (e.g., predictive modeling, agent-based models, and discrete event simulations) and emerging devices (e.g., smart sensors, augment and virtual reality, exoskeletons, and building information modeling) to develop and evaluate innovative solutions needed to attain a sustainable construction workforce.

Nnaji has published his research in reputable outlets such as the American Society of Civil Engineering Journal for Construction Engineering and Management and the American Society of Safety Professionals Professional Safety Journal. He has presented his research to local, regional and international audiences.
