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.
Choose a supervisor who makes you excited about your project. There will be times when your project does not go as planned and reminders of that enthusiasm and why you are doing the work are crucial to continuing through the hurtles.
I would tell prospective students that pursuing graduate studies at UofG is a good choice, as they provide students with the opportunity to learn in a classroom, along with research opportunities. The research opportunities give you an opportunity to put the knowledge you learned in the classroom into a real-life situation. The research that you will pursue will add valuable information to the academic and industry community.
I have found success in graduate studies by having a solid group of people supporting me. Academia can be daunting and difficult, but having friends and colleagues who are like-minded, engaged, and generally supportive has made my journey possible. Pick your department and supervisor with care, seize opportunities, explore new and old interests, maintain hobbies outside of research, and most of all: stay curious.
Make your research project/thesis something you're passionate about. If you have a great idea, take it to a professor and see if you can make it into a project.
The graduate life experience is great! There are a ton of activities and ways to get involved on campus. The administration, faculty and fellow student truly provide a supportive environment to learn, grow and be challenged.
