About Me

Yin Leng, Kua is currently an Assistant Professor of Chemical Engineering at the School of Energy and Chemical Engineering, Xiamen University Malaysia. Back in the year of 2012, she worked as an engineer in the industry of inorganic coating and electroplating on rare-earth magnets with Shin-Etsu after she completed her undergraduate master degree from the University of Nottingham Malaysia. Dr. Kua is currently teaching Unit Operations of Chemical Engineering II, Oils and Fats Technology and Bakery Engineering. She also contributes to the supervision of final year capstone design and research projects for the programme of Chemical Engineering as well as New Energy Science and Engineering.
