Julianna Lee: From extension to education

Julianna Lee '24 joined the Nutrient Management Spear Program (NMSP) as an undergraduate. During her time at Cornell, she earned a bachelors of science in agricultural sciences and minored in education and Asian American studies. Read on to learn more about her work with NMSP’s dairy sustainability team and to see what’s next for her.

When you first started with NMSP, what was your position like?

I started with NMSP in 2022 as a precision agriculture intern, working with Data Analyst Manuel Marcaida. I already had an interest in agriculture and engineering at the time, so one of my professors recommended that I apply.

Why did you decide to continue with the team? How did your position evolve after your internship?

Every week, different NMSP research teams present their work to the rest of the members of the program, so I got a good idea of what opportunities were available. After learning more about ongoing projects, I realized that my true interests aligned more with the dairy sustainability program’s work.

What really drew me to this program was the amount of extension involved — my passion for teaching was growing, and extension was a good way for me to get more experience with that.

What was your day-to-day experience once you joined the dairy sustainability team?

Working directly under Olivia Godber (research associate and head of the Dairy Sustainability Program), I spent a lot of time analyzing data using Cool Farm Tool and developing nutrient mass balance reports. We would use information about farm operations provided to us by collaborating farmers and produce reports that could be brought back to the farmers as data-supported feedback.

As a part of my work with the team, I also looked into nutrient balance for the whole state of New York, contributing to a paper that is currently under review. I got to experience the research and paper-writing process from start to finish.

On top of that, I helped with a number of extension-related deliverables. I revamped the slides for nutrient mass balance and Cool Farm Tool reports to make them clearer and reader-friendly for our audience. I contributed to a What’s Cropping Up? article, helped write four fact sheets, and I put a lot of effort into creating a one-pager summarizing the dairy sustainability program. I also reworked the poster about our project, which is used to show prospective members and supporters what our work is all about and what we’ve accomplished over time.

I’m really grateful that I got to contribute to so many resources that strengthen NMSP’s connection with farmers and stakeholders.

You were really looking forward to getting more extension experience. What are some of the different hands-on extension activities that you helped with?

Quirine Ketterings (professor of nutrient management in agricultural systems and NMSP lead); Olivia, who was my direct supervisor; and several of us on the dairy sustainability team periodically visited with farmers and reported what we’d learned from our analyses of their operations. We had conversations with them about potential improvements, as well as what they are already doing phenomenally well. Besides being enjoyable, it was always clear that this was an impactful, critical part of our extension mission.

I also got to present our work to larger groups many times every year. As an intern, I presented at poster sessions to other undergraduates, professors and peers. I showcased our work at the Aurora Farm Field Day and the Cornell Cooperative Extension Agriculture In-Service Conference, and contributed to NMSP’s dairy sustainability webinar.

After being a part of the team for a while, I was a teacher’s assistant for the Whole-Farm Nutrient Management class, ANSC4120/6120, taught by Quirine Ketterings and Mike Van Amburgh (professor of dairy nutrition). Karolyn Auer, who was an NMSP team member at the time, and I worked together to help students conduct whole farm mass balances and greenhouse gas footprint assessments. This brought together everything that I’d worked on up to that point and gave me even more hands-on teaching experience.

These opportunities really solidified my passion for teaching, extension and supporting New York farmers.

Can you share more about some highlights of your time with the team?

Lunch was always a great time to connect with people. I learned so much about other team members — and about life — during our lunch discussions. I really enjoyed the long talks during drives to the field and all of the inside jokes we’ve had through the years. It was great to consistently push myself out of my comfort zone and find my passion in the professional world while also feeling more confident in myself as I connected with others.

As someone that is not from an agricultural background, this experience was a great way to learn about what a dairy farm is, the collaboration between farmers and various stakeholders, and the importance of extension. It made me appreciate the work that farmers do.

Where are you going next? What will you take with you from your time with the team?

This fall, I’m attending Columbia Teachers College to pursue my master’s degree in sociology and education.

Working for NMSP showed me how important it is to be professional in the workplace, the true meaning of collaborating with a bunch of different stakeholders and how to adjust my communication methods based on my audience. I also learned how great it is to chat with people from diverse backgrounds, whether they are from different countries or educational contexts. I know that I will take many personal and professional lessons, as well as many friends, with me moving forward, and I’m very grateful for that.
