Dr Guangyao Si is an Associate Professor at the School of Minerals and Energy Resources Engineering. He was initially trained as a mining engineer at the top mining university in China, China University of Mining Technology. He graduated as the top student among nearly 280 mining peers in 2010. Due to his excellent academic performance, he was awarded three scholarships by Imperial College London to sponsor his PhD research under the supervision of Professor Sevket Durucan. Guangyao defended his thesis in 2015 with outstanding research outputs and then continued his work at Imperial College London as a Research Associate until the end of 2017. In December 2017, Guangyao moved from the UK to Australia to take a faculty position at UNSW. Having been studying and working for the mining industry on three different continents, Guangyao is determined to devote himself to exploring fundamental knowledge boundaries as well as developing industry-oriented research solutions.
