Biography

Ir.  Dr. Ngu Lock Hei received her BEng (Hons) in Chemical from University of Science, Malaysia in 2011 and her M.Eng and Ph.D. in Environmental Engineering from University Malaysia Sarawak respectively in 2004 and 2008.  The research emphasized the development of enhanced circular phase gravity separators with coalescence plates for wastewater treatment.  Dr. Ngu also has a Professional Certificate in Teaching Practice from Swinburne University of Technology in 2014. She is also a Professional Engineers registered with the Board of Engineers, Malaysia (BEM), a corporate member of the Institution of Engineers Malaysia (IEM) and a registered Green Building Index (GBI) Facilitator. She serves as accreditation panel for Engineering Accreditation Council Malaysia (EAC).
