Biography

Dr. Obinna Onuaguluchi joined the Department of Civil Engineering as a postdoctoral fellow in 2014. He obtained his Ph.D. from the Eastern Mediterranean University in 2012. As a Research Associate, Dr. Onuaguluchi’s studies over the past years have been centered mainly on material sustainability and the reduction of the negative carbon footprint of the construction industry. In collaboration with industrial partners, the development of durable cement-based applications, reinforced with biomaterial, and the valorization of industrial byproducts as additives in cement composites are the main thrust of his recent research activities.
