Tim Pasang

Dr. Pasang received his Ph.D. from Monash University, Australia in 2001. He spent a number of years as Research Engineer at the Indonesian Aircraft Industry. He worked as Senior Consultant at the PSB Corp, Singapore in 2001-2004 before moving to New Zealand. His research area covers various aspects of materials and manufacturing especially welding, metal forming, machining, biomaterials and metal additive manufacturing. He was the Head of Department of Mechanical Engineering at Auckland University of Technology - AUT (2012-2020), and also the Director - Engineering Research Institute (ERI: 2016-2020), Auckland - New Zealand.

Prof. Pasang was a Loewy Visiting Professor at the Materials Science and Engineering Department, Lehigh University between 2010 and 2015; Visiting Professor at the Department of Mechanical Engineering, Akita University Japan between 2009 to 2019, and also Honorary Professor at the Department of Mechanical Engineering/Institute of Mechatronic Engineering at National Taipei University of Technology (NTUT) - Taipei, Taiwan since 2019. Prof. Pasang was a recipient of the Japan Society for the Promotion of Science (JSPS) Fellow in 2013.
