About

Isaac is specialised in the field of physical and powder metallurgy, as well as nanoscience and nanotechnology. His research interests range from advanced consolidation and alloy development of commercial micron-sized powders for pore-free engineering components to novel green (e.g. precursor-free) synthesis of nanoparticles with well controlled structure and composition, for industrial applications in transport, energy, healthcare, defence and electronic sectors.

Isaac holds 4 patents and has published over 97 research papers in scientific journals, book chapters and conference proceedings. He has been a member of the editorial board for International Journal of Powder Metallurgy.

In the past, he has received research funding from EPSRC, AWM, DSTL, AEC, AlPoCo, MNL, IMPT and the Royal Society. He has most recently received a major NERC funding, together with colleagues from Schools of Health & Population Sciences, BioSciences, Chemistry and Geography, Earth & Enviromental Sciences at The University of Birmingham. This award aims to research on the impact of nanoparticles to health.

He is a member of the Particulate Engineering Committee for the Materials Science & Technology Division, which gives advice to the Institute of Materials, Minerals and Mining on strategies for promoting new particulate engineering technologies and raising the profiles of UK particulate engineering technology sectors. He is the Founder and Director of a spinout company, known as Metal Nanopowders Limited at the University of Birmingham, specialising in the novel and cost-effective synthesis of well controlled metallic and non-metallic nanopowders.

Biography

Isaac Chang graduated with a BSc(Hons) degree in Materials & Metallurgy from Imperial College, London University in 1986. He pursued his postgraduate study under the supervision of Prof Brian Cantor at the Department of Materials, Oxford University, where he obtained a DPhil in Materials Science in 1991.

He stayed on and worked for Prof. Brian Cantor as a research fellow at The University of Oxford University in the field of rapidly solidified metallic glasses and nanocomposite thin films. In 1995, Isaac joined the School of Metallurgy and Materials, Birmingham University as a Lecturer.

He was promoted to Senior Lecturer in 2003. He obtained Chartered Scientist and Fellow of Institute of Materials, Minerals and Mining in 2005. He became the Head of Learning and Teaching for the School in 2010
