Dr Stephen Asomani Ntiri has over six years’ experience in analytical physics and mathematics. He has worked in academia and his research has led to many publications. He has experience of teaching a wide range of analytical physics and mathematics to audiences from foundation year to M.Sc. On August 1, 2022, he began teaching science modules on the Foundation Year Science programs at the University of Nottingham's Centre for English Language Education (CELE) in Ningbo, China. 

I have experience of teaching under-graduate and post-graduate taught modules in Analytical Physics. I also have experience of teaching statistics and mathematics for scientists.

My Scientific research interest is in the area of fluid machinery and engineering, and has made some innovative work on theoretical and numerical optimization of flow performance, unstable flow inside centrifugal pump and its flow-induced vibration and noise.
