Radin Maya Saphira Radin Mohamed (PhD) is an Ascociate Profsessor at the Department of Water and Environmental Engineering, Faculty of Civil and Environmental Engineering, Universiti Tun Hussein Onn Malaysia (UTHM) in Batu Pahat, Johor, Malaysia. She has been working with the UTHM since 2004. She graduated with a PhD with her thesis on Environmental Impacts of Greywater Reuse on Home Gardens, from Murdoch University, Perth, Western Australia. Radin Maya Saphira's research involves issues related to improve environmental quality related to their improper discharge. In the last few years, she has extended her research interests to include the low cost treatment system to alleviate the untreated greywater discharge. She is most interested in the use of natural processes and locally available materials. She has coauthored 36 articles in international research journals and a chapter in the book "Cellulase: Production, Applications and Health Benefits" NOVA Science Publishers(2016) and Fourchapters in Handbook of Environmental Materials Management (Springer publisher, 2018). She has also contributed to three teaching modules on environmental engineering.
