Dr. Mariod is the founder of Ghibaish College of Science & Technology, Ghibaish, Sudan. He is a professor at the Department of Biology, Faculty of Science & Arts, Alkamil, University of Jeddah, Saudi Arabia. He obtained his PhD in Natural Sciences at Münster University, Münster, Germany. Dr. Mariod was considered for inclusion in WHO‘S WHO in the World, 28th Edition by Marquis Who’s Who Publications in May of 2010. He was also classified among the top 2% global highly cited researchers published in PLOS Biology by Stanford University in 2019. Dr. Mariod has obtained more than eight innovations medals and awards as well as nine scholarships and grants. He serves as an editorial board member in nine international journals, and he has published 212 articles in peer-reviewd journals. Dr. Haroon Elrasheid Tahir is an associate professor at Jiangsu University, where he obtained his PhD in Food Science and Biological Engineering. His research areas include nondestructive detection techniques for food quality, natural product chemistry, edible coatings, colorimetric sensors, and analytical chemistry. Dr. Tahir has published 61 papers and 30 book chapters, and he coedited the book "Roselle (Hibiscus sabdariffa) Chemistry, Production, Products, and Utilization"; and "Colorimetric Sensors: Techniques to Measure Food Safety and Quality", both published by Elsevier. Dr. Mahunu is an associate professor at the University for Development Studies, Ghana. He is a full-time lecturer at the Food Science and Technology Department. He obtained a BSc in Agricultural Technology (Horticulture option) from the University for Development Studies, Ghana; an MSc in Pomology, the Kwame Nkrumah University of Science and Technology, Ghana; and a PhD in Food Science and Biological Engineering, Jiangsu University, China. His main research areas include studies on the mechanisms of action of microbes and other bioprotectants (such as natural plant extracts) acting as biocontrol agents of postharvest pathogens of horticultural and fruit crops, the optimization of the activity of these agents, mycotoxins in foods (e.g., patulin in apples), prevention induction, monitoring, and detoxification of mycotoxins in postharvest fruits and vegetables, improvement of quality and food safety practices in the food production systems, functional foods, and food product development.
