My advisor was more like my mentor. He is very open, honest and helpful, which made me very comfortable to express my ideas and also to discuss different issues concerning my academic life.
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.
I loved being a PhD student here. My advisors and labmates were all very supportive of my research endeavors. I enjoyed being in charge of my own research project.
Workshops offered through the library and OpenEd are so beneficial to help with your research goals and teaching tips/tricks. Definitely be sure to check these out!
There was a great graduate student community in my home department of Integrative Biology. As a group, we organized events ranging from salsa lessons and weekly communal meals, to wilderness retreats and a 'March Mammal Madness Bracket' pool.
Have really good time management! Being ahead on a project will do you wonders when deadlines start to creep up. And don't be afraid to make mistakes and not be entirely sure what you want to accomplish from the start. Faculty are there to help and guide you on your journey but you must also be willing to be challenged and accept productive criticism.
Make sure you need grad school for your future career before you do it. Reach out to other grad students while you're in undergrad; most people will be more than happy to share their experiences.
