Reader, BCAST

Dr Hari Babu Nadendla joined Brunel University London in 2006. Prior to that he was a Research Fellow (1999-2002), then a Senior Research Fellow (2002-2003) and, ultimately, Advanced Research Fellow (2003-2006) at the University of Cambridge. He has published over 200 papers in international peer reviewed journals and holds 4 international patents. He was awarded the PASREG award of excellence in 2007 for his outstanding contribution to the development and characterisation of bulk high temperatures superconductors. During his post-doctoral career, he received best poster presentation awards. Since joining BCAST, his research has expanded from processing of superconducting materials to understanding the heterogeneous nucleation process during solidification, developing chemical grain refiners for Al and Mg alloys, processing of high performance MMCs using intensive melt shearing, and twin roll casting Al-alloys from a recycled source for automotive application.
