Dr. Koh Soo Jin Adrian received his PhD degree in Mechanical Engineering and Integrative Sciences from the National University of Singapore in 2008. He is currently an Assistant Professor at the Department of Mechanical Engineering, National University of Singapore, and an Adjunct Scientist at A*STAR, Institute of High Performance Computing. He was a post-doctoral fellow at Harvard University, School of Engineering and Applied Sciences, between 2008 and 2010. His current research interest is in soft electroactive polymer systems, in particular, using soft materials like dielectric elastomers as artificial muscles for soft robots, and generators for motion-based energy harvesting. He is the recipient of the inaugural Philip Yeo Prize in 2007, which recognizes outstanding research performed by a graduate student or post-doctoral fellow in Singapore. In 2013, he was awarded the “Promising International Researcher Award” by the European Scientific Network for Artificial Muscles (ESNAM), for his contributions in the field of electroactive polymers.
