Dr. Zaka Emad
Associate Professor, Department of Petroleum Engineering
Mining Science & Engineering Program
Dr. Zaka Emad, a distinguished expert in Mining Engineering, joined the College of Petroleum Engineering and Geosciences (CPG) at KFUPM in November 2024, bringing a wealth of expertise and passion for innovation in the field. Before this, he spent a decade shaping minds at UET Lahore, focusing on underground mine design, rock mechanics, and rock fragmentation.
His impressive postdoctoral research at Creighton Mine in Sudbury, Canada, explored numerical modeling of destress blasting, while his Ph.D. work delved into the dynamic performance of cemented rockfill under blast-induced vibrations. With over 17 years of teaching and research experience, Dr. Emad is a pioneer in underground mining, excavation techniques, rock mechanics, mine safety, and numerical modeling. His commitment to advancing knowledge and solving complex challenges makes him a vital asset to the CPG and the broader mining community.
