This book is a celebration of our people’s minds. It is an acknowledgment of their relentless search for new knowledge; a testimony of their tenacious quest for excellence. Research has always been at the forefront of UPM’s commitments as one of the leading universities in the nation. Our research achievements on both the local and international front serve as proof of that commitment. If there is one thing about UPM that the academic and research world firmly attests to, it is the fact that we are perpetually evolving, both in knowledge and vision. There is no end to what we aspire to achieve in the world of research, development and innovation. More importantly, there is no end to our passion to want to contribute to humanity through the creation of new knowledge. The researchers featured in this book are people who have brought fame to UPM through their remarkable research achievements, and they are only a small part of the many more who form the backbone of our university.
