There are so many ways to pursue your passions and interests. I'd recommend that prospective grad students be certain that they are ready for the rigour and commitment required by graduate studies. Be open to new ideas, critiques, and other ways of seeing the world. Learn from your peers, students, university staff, and the wider community, in addition to your professors. Be generous with others and build community. Don't forget where you come from.
A right step taken at a right time completely changes your identity. I won't say that your academic journey will be easy, but I am sure it will be worthy.
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.
My research dealt with using biostimulants as environmentally friendly alternatives to fungicides, for preventing dollar spot disease, which is one of the most prevalent disease that affects turfgrass on golf courses worldwide. My research will hopefully help to identify species and cultivars of turfgrass that respond positively to various biostimulant applications and therefore have a lower disease incidence. This will potentially allow golf course managers to use fewer fungicides in the future by switching to biostimulant applications, which will reduce the environmental impact that they have on the surrounding ecosystems.
Remember that research never goes as planned and to not let failed experiments or unwanted results keep you from working hard on your degree. No one gets through graduate school without failed experiments and huge changes in their project plans.
In graduate studies, you will work harder than you have ever worked, but it is going to be so rewarding. There are experts in every field at the University of Guelph, who will support you and offer so many resources that are available to help you succeed. You are also going to meet some incredible people along the way, especially since there is such strong comradery among fellow graduate students. I know this is a cliché, but I think you get out of your time here what you put into it, and there are so many opportunities available to take advantage of, to ensure you have a great experience.
Words of advice for someone considering graduate school.
Do not hesitate to ask questions in all aspects of overseas study. Your peers, professors, graduate coordinators, and everyone you meet here would love to help.
To future graduate students, it is important to keep a clean, legible, and logical lab notebook! Also remember that your brain is your best weapon to succeed in graduate school and it functions best when it is well-rested; only pull all-nighters if necessary. Learn to manage your time and try not to do multiple things at once; multi-tasking in the lab can lead to errors in experiments. Finally, enjoy your time and get all the food and freebies from conferences and other events!
Smart or slow, doesn't really matter in the end, the point is everyone has their own time zone, all you have to have is your own balance of work, play, and all other stuff, the others don't really matter.
