To date, I have published at least 190 research papers in various renowned worldwide journals & repositories, including three co-authored books that can be seen on Google Scholar. I also advised numerous MSc & Ph.D. students for their research studies and have been invited to examine Theses' and dissertations' final presentations & defense at various universities in Ethiopia, Eastern Africa, University of Rostock, Rostock, Germany, and the Philippines. I have been in academia for more than 20 years and teaching courses in the Master's programs of Civil Engineering (Construction Engineering and Management, Highway Engineering, Transportation Engineering, Road and Transport Engineering) in Ethiopia, Eastern Africa, and the Philippines. In addition, my 22 years of experience at the Department of Public Works and Highways, Region 02, Cagayan Valley Region, Philippines, has added to my knowledge and made me comfortable demonstrating the actual situation during my class lectures and research work.
