To date, I have published at least 190 research papers in various renowned worldwide journals & repositories, including 3 co-authored books that can be seen on Google scholar. I also advised numerous MSc & Ph.D. students on their research and have been invited to examine Theses' & Dissertations' final presentations & defense at various universities in Ethiopia, the Philippines, and the University of Rostock, Germany. 
I have been in academia for long 18 years and teaching courses in the Master's programs of Civil Engineering (Construction Engineering & Management, Highway Engineering, Transportation Engineering, Road & Transport Engineering) in the Philippines and Ethiopia, Eastern Africa. 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 in demonstrating the real situation during my class lectures and research work.
