She has also worked in sales, making the business case for technological change amongst brand and shopper marketers within CPG companies. She studies Sustainability Management in order to grasp these sustainability skills needed to make the business case for sustainability.

Q. You’re pursuing a degree in an environmental-related field. Are there hands-on experiences you’re using to supplement your online learning?

A. Yes! At Columbia University we have a program called Net Impact, which is a club for pro-bono consulting. This consulting work focuses specifically on sustainability and impact. I, alongside of a team, participated last semester consulting for a fashion brand to calculate their carbon footprint comparison and market that to consumers. It really helped me apply a real-life business situation to my sustainability studies.

Q. What was the biggest challenge for you when it came to online learning?

A. The biggest challenge was naturally meeting people. You don’t realize how easy it is to make friends in person when you no longer have the luxury of small talk waiting for class to begin or walking out together! I definitely took that for granted during undergrad.

I’ve since learned to proactively set up Zoom chats with people outside of class. It’s certainly helped!

Q. On the flipside, what was the best part of online learning for you? What advantages did you enjoy?

A. I loved the flexibility of being able to take classes wherever. For the first time in my life, I don’t feel the pressure of making life choices with regard to moving or staying in one place due to a commitment such as graduate school. It’s allowed me to be able to try living in Arizona to see if I want to long term. If school wasn’t virtual, I wouldn’t be able to do this.

Q. What advice would you give someone who is considering an online degree in a field related to environmental science?

A. I think the field is growing exponentially and there is so much demand for this kind of expertise inside of corporations. When you look at applications for respective jobs, there are specific skills needed that generations were not taught during undergraduate curriculums. Therefore, the Masters and higher-level learning is so imperative to be considered in this field to actually enable positive environmental change.

Q. What do you wish you had known about online learning, especially at the master’s level, before you started the program?

A. I was unsure as to whether or not I would be able to handle the coursework. I decided to take five courses my first semester which is one more than the normal, full time graduate student. What I’ve found, however, is that there is barely any memorization, which was always my downfall. I learn best by doing, and practicing, and that is what graduate school is all about.

Therefore the coursework was right up my alley. Rather than being bogged down with all of the assignments, I felt super engaged since most of them were all about practicing the skills and developing the respective work

Q. Anything else you’d like to add about earning the master’s in environmental science or a related field?

A. It is such a great field to study. You’ll find that a lot of the people you are studying with have so much heart, given the purpose of study. I think it’s different from studying something like Accounting or Finance where your passion can be abstract, or not really even in it. Environmental students can always come together on one thing – caring about the Earth in an altruistic manner.
