Pursue research that you are passionate about and that inspires you. Graduate studies are a lot of work and can be difficult, and if you're not passionate about your research then you probably won't enjoy it. That being said, don't be afraid to step out of your comfort zone and experience new things, whether that be academically or personally. Also, don't be afraid to get involved, some of my greatest experiences at the University of Guelph have been outside of the classroom.
Absolutely take the time to reach out to current students, alumni, and faculty members affiliated with the grad programs of consideration. Your grad school experience will very much be influenced by the people you are surrounded by during your education and the culture of the program. Hearing from other's experiences and talking to current students is one of the best ways to find the right fit for you.
Pursue research that you truly believe has the potential to improve life. Knowing you are working toward something more than just a degree can help you find the drive to make it through the difficult or dry aspects of your time in graduate studies.
Your time in graduate studies will provide many opportunities, but don't lose touch with yourself. Take the time to do what you need to in order to maintain your sense of purpose and direction, then live out of that. Don't be afraid to try new things, but remember that no one can do everything. Be selective.
A graduate student at the University of Guelph is a lot of work, but it is very rewarding. My schedule was even more flexible now than when I was an undergraduate student, which is very important because you have to make time for everything. There are classes and seminars, research, meetings, Teaching Assistantship(s), mentoring, and readings happening constantly. If you plan things well, you can get involved on campus or have a social life, too!
I would encourage all prospective graduate students to research their program of interest and speak directly to faculty prior to applying as this can ensure that your research goals align with your prospective advisor/program of choice.
My advice for prospective grad students is to reach out to people. When I was looking at the CDE program, I reached out to a couple of graduated students in different fields to talk about their experience in the program. This information was very valuable and helped me to make a confident choice. If you have any questions about the program or my experience please feel welcome to reach out.
From my experience as an international student, I would request every prospective grad student to understand the core details offered by every course in the food safety and quality assurance program. I know every course is research-intensive and requires dedication and time management, but trust me, if you are passionate to establish yourself in the industry and want to ensure consistent delivery of safe food to the customers, you will develop a strong interest in the course. The application-level offered in the assignments is a reflection of how it is applied in an industrial setting and helps you crack the real-life hurdles faced in the rapidly growing industry and globalization. I would also suggest the prospective graduate students engage themselves in thoughtful conversations with their peers and develop a strong sense of food safety leadership to facilitate those conversations. It is also highly recommended to attend the food safety seminars provided by the department.
My advice to any prospective grad student is to not rush into graduate school without some self-reflection about your passions, what you love doing and what you would like to study. This is because grad school can be a challenging place but also incredibly rewarding as it teaches you how to read critically, learn systemically, and think deeply. As such, I invite potential students to engage in some introspection and self-reflection about your motivations, desires, and commitments as this is a weird (but wonderful) experience distinctive from both undergrad and from other jobs so its important to not rush into anything without thinking.
