Biography

I obtained my PhD in 2012 from Universiti Kebangsaan Malaysia, of which the area that I investigated was the improvement on the data envelopment analysis. I am an associate professor in the School of Mathematical Sciences since 2016. I was involved in various revamp cycles of mathematics modules in the foundation level, setting up the BSc Mathematics and Management programme as well as leading the programme accreditation process.

Expertise Summary

I contributed in computational improvements in various areas including data envelopment analysis, fuzzy models, long memory processes, Markov switching models and state space models.

Teaching Summary

I currently convene the modules of statistics and statistical inference.

Research Summary

I am interested in various aspects of computational statistics, My research area involves state space models, Markov switching models and long memory processes, and time series analysis.
