Teaching is my preferred career path. At the Faculty of Food Science and Technology, my teaching activities includes mentoring, supervising, and teaching the next generation of thought and practice leaders to be a wonderful privilege. Giving back to the profession I love and believe in is one of the primary motivators behind my teaching. My teaching strategy is to engorge the students to learn and make them realize that they are responsible for their education that will guide them to success in their life and future career. My main concern is to make my students understand the differences between urgent and important tasks during their few years at the university. Moreover, my students will learn how to use the time wisely to have leisure time that does not have effects on their main goal for excellent education. Off course, students are the center of the classroom, but they need to understand the purpose of each course they study so they can make striking progress and achieve academic success.
The future challenges in food security and safety have urgent need for future researchers with critically thinking and ability to analyse situations to solve problems including social and economic issues. Therefore, I always give examples of current and future challenges for providing healthy foods to the increasing number of human populations. The students still have to know the basic terms used in the discipline that will be very necessary for the success of the learning process. During the lecture I allow my students to ask questions related to the discussed subject because I believe there is no point to proceed to the next line if the students did not fully understand the previous point. I also give some time to discuss the topic with the students and listen to their own opinions and defend it in an intelligent and articulate manner. I believe that my responsibility and duties is to teach the student and the students’ responsibility is to learn, and my job as a lecturer is to make their learning easier. I do not do that by spoon feeding my student but by making them interest to learn my subject by using innovative methods, respond to questions, and encourage my students to seek knowledge.
I love teaching because is the best way to learn and improve my knowledge especially if I assigned to teach new subjects. I enjoy teaching topics of food science including dairy technology, food chemistry and food microbiology. My future task to teach food microbiology and food safety classes involves teaching students from different backgrounds and they are unfamiliar with course, therefore I often depart from conventional teaching methods to ensure the entire class develops the requisite skills and grab the information presented. I taught great number of students for laboratory exercises in food microbiology and actually I prefer to carry out the teaching and the lab exercises of the same subject to make the students comfortable and able to transfer the knowledge they acquired in the class to the lab.
The courses that I teach are presented in-depth to address the current and future issues, I follow the syllabus of the faculty, but I also highlight modern challenges that are not covered. My 3 hours lecture is usually divided as the first hour I present the topic information, second hour I carry out workshop with examples and the last hour I ask the students to present the information they received. The topics have broad range that covers microorganisms and their use in food production, control point in food industry. Emphasis is placed on applied technology rather than microbial theory. Thanks to my great teachers, I learned how to summarize the significance of the course and discuss the points with the students to make them interested in the subject. By the end of the course that I teach, my students will realize that food science is great major of study that has great impact on the socioeconomic of the society.
Part of the learning process that helps to build the confident between the lecturer and the students is the interaction outside the classroom. I have no set office hours, rather I encourage students to visit my office when they have an opportunity and discuss issues relevant to the course and their undergraduate or graduate career. I also encourage my students to contact me by Email or whats app if I am on travelling and by phone if I am at the campus. I want my students to feel I am approachable, and I care for their concerns regarding my teaching courses.

The recent Covid-19 pandemic demonstrated the willingness of our students at Universiti Putra Malaysia to engage with via virtual classrooms. I have started the utilization of the technology in teaching before the recent shifting from conventional classrooms to virtual classrooms. This has given me the opportunity to benefit from some forms of technology in the virtual classroom and to make teaching and learning more effective for all my taught courses. The technology has improved my student’s engagement, individual learning, collaboration, and learning useful life skills. The technologies I implemented includes the following:
1. Putrablast: Used in virtual classrooms, share the lecture notes and external readings. Carry out quizzes and final exams.
2. Zoom: This App was heavily used in virtual lectures and for students’ group presentations.
3. Biorender: I used this online App to develop a very comprehensive and effective slides with life drawing that can simulate real food industry.
Current Research Interest:
My research interests include the development of bioactive peptides from sustainable low-cost plant-based sources for the applications as natural preservatives. Currently, as the Research Leader of International Collaboration Fund (ICF) between the University of Alberta and Universiti Putra Malaysia, my research is focused on producing functional food and beverages that enhance the functions of the immune system. My research has focused on bioactive compounds from fermentation process. The work involved long hours of laboratory work to isolate the peptides, a lot of knowledge about LC/MS-MS and proteomics to analyse the obtained data. I developed my skills of using advanced software for analysing the data and identifying proteins and peptides.
Research Accomplishments
1. Application of lactic acid bacteria in food preservation
Lactic acid bacteria isolated from Malaysian environment and screened for their antifungal activity against spoilage fungi the cause damage to foods and health risk because of the toxins they produce. The selected isolates inhibited the growth of spoilage fungi in broad range of foods. The bioactive compounds identified were antifungal peptides with strong activity towards several spoilage fungi. The significant of the project was to develop natural food preservatives from lactic acid bacteria fermentation to fulfill the two important current gaps in food industry which is the need for natural preservatives. My research expanded the potential to apply lactic acid bacteria antifungal peptides in selected foods to extend their shelf life. My research papers were published in highly cited journals including Food Control, LWT-Food Science and Technology, and Journal of Food Science.
2. Probiotic fermented foods with potential to improve the immune system function
My research focus on developing plant-based fermented foods that has probiotics as co-culture to enhance the health benefits. I developed a probiotic fermented glutenous rice (Tapai Pulut) with enhanced health benefits compared to the traditionally fermented glutenous rice. I received fund from Ministry of Science, Technology, & Information (MOSTI) and appointed as Research Leader of International Collaboration Fund (ICF) between the University of Alberta and Universiti Putra Malaysia. The objective of the research project is to develop plant-based functional foods that enhance the immune system function.
3. Lacto-fermented camel milk for health promoting
Fermented camel milk is consumed by the traditional tribes in the Sahara of Iraq as source of energy and is believed by the locals to have many health benefits. The main issue for the production of fermented camel milk by natural fermentation is the safety issues and the variation of the product from batch to batch. In this project, I solved that issue by testing and developing the suitable strain that result in highly acceptable taste and strong antimicrobial activity. The fermented product was confirmed to inhibit the growth of several pathogenic bacteria in comparison to the fresh milk. The active compounds were identified as bioactive peptides that have the potential for several biological activities and can promote the health of the consumers. My research group observed the healthy status of the dessert people in the Sahara, and we started to study their diet. Our group found the fermented camel milk to be the significant food that promoted the health of the tribe people. We optimized the fermentation conditions to produce stable product with higher antibacterial activity that will help the consumers to improve the general at low cost. The fermentation technology was transferred to many local companies that produce dairy products to include the fermented camel milk as regular daily produced and consumed product for easy access by the consumers. The finding and the recommendation of the project led to increase the public concern regarding the health benefits of fermented camel milks. Three papers were published as a result of this project.
4. Traditional foodstuff role during disasters
Recently, I am studying the traditional foodstuffs and their important role in household food security. I started the research to strengthen the food security and bring the attention of policy makers towards the traditional foods as a strategy to ensure the food supplies for communities during natural and man-made disasters. No research has, however, attempted to examine traditional foodstuffs in light of disasters and crises. Such research can provide a useful outlook on how traditional foodstuffs can aid households in a situation of disrupted food supply. I published the first article at Appetite on ScienceDirect.
Achievements
1. Developed method for the production of bioactive peptides and applied as natural preservatives in processed foods.
2. Determined the antifungal peptides mode of action against food spoilage fungi and reduce the economic losse.
3. Developed number of fermentation methods to produce several fermented food products with health benefits to the consumers.
4. I have published 40 papers in the last five years in ranked and recognized journals, and this was my contribution to the field of food science.
