Philip Zhang is a senior research scientist in Callaghan Innovation’s Data Science team.

He joined Industrial Research Ltd (now Callaghan Innovation) in 2008 with a PhD in applied maths from Massey University, working on mathematical modelling of industrial processes.

Philip has been working in Data Science fields and Industrial Modelling since 2010 and he has completed numerous projects for New Zealand companies.

Before immigrating to New Zealand, he was an associate professor at Chongqing University. Philip has established and maintained active connections with many applied mathematicians in New Zealand and overseas.

He was a visiting scholar at Cambridge University in the UK, Dresden University of Technology in German, Cergy-Pontoise University in France and the Institute of Computational Maths of Chinese Academy of Science in China.
