Ching Lik Hii

Associate Professor,



Dr. Hii received his BEng (Hons) degree in Chemical Engineering (University of Manchester Institute of Science and Technology, 1996), MSc degree in Food Processing and Engineering (Universiti Putra Malaysia, 2004), and PhD degree in Chemical Engineering (University of Nottingham Malaysia, 2010). In August 2010, he joined the Department of Chemical and Environmental Engineering (UNM) as Assistant Professor and promoted to Associate Professor in 2013. He is also Director of Undergraduate Studies for Dept. of Chemical & Environmental Engineering. Dr Hii is a Professional Engineer (PEng) registered with Board of Engineers Malaysia, Chartered Member of the Institution of Chemical Engineers (MIChemE), Chartered Engineer of the Engineering Council UK (CEng) and Fellow of the Higher Education Academy UK (FHEA). He is also Committee Member of the IChemE Food & Drink Special Interest Group and Chair of the F&D SIG Malaysia Chapter. Beside teaching and research, he is involved in student activities as Advisor to UNM-IEM Student Section and Co-coordinator for the UNMC BlueSky Charity Project.

Current Research

Dr Hii current research interests are in the areas of modern drying & dehydration technologies, preservation of food antioxidants/nutrients, bio-products processing and computer simulation on heat & mass transfer during drying/diffusion (Google Scholar). In the past and including to date, he has carried out research for several types of agriculture/food products such as cocoa beans, chocolates, star fruits, herbs, kedondong, chicken meat, papaya leaf and also investigated/developed several processing technologies such as heat pump drying, adsorption drying, stepwise drying, hybrid drying and solar drying. Particularly, he is interested to investigate the effect of processing on the quality and antioxidants/nutritional properties of underutilized agriculture materials in his current research. Outcomes of research have been published in several international peer review journals such as Drying Technology, Journal of Food Engineering, Journal of Food Process Engineering and International Food Research Journal. His current research collaborations are with Universiti Putra Malaysia (UPM), Forest Research Institute Malaysia (FRIM), Malaysian Cocoa Board (MCB), Diponegoro University (Indonesia) and Crop for the Future (UK-Malaysia).

Currently, Dr Hii is also looking into aspects of engineering education and have carried out studies in classroom design attributes and web interactive technology in teaching.
