In the vast fields of agriculture, where innovation meets sustainability, young researchers like Alexa Nicole Peterson are paving the way for a greener tomorrow. With a passion for solving pressing global challenges and an unconventional journey that took her from computer screens to sprawling farmlands, Alexa is redefining what it means to grow for the future. 

Born and raised in Canada, Alexa Nicole Peterson’s educational journey started with a bachelor’s degree in Computer Science at the University of Manitoba. However, as she delved deeper into her studies, she realised her heart wasn’t in programming but in something more tangible, dynamic, and impactful. 

“I love understanding how things work, but staring at a screen all day wasn’t fulfilling,” she recalls. “I wanted to work with my hands, be outside, and make a difference.” 

This realisation led her to switch to Plant Biotechnology, where she focused on genetics and breeding. Her interest in sustainable agriculture blossomed during her master’s program in Breeding and Plant Science at the same university, where she worked on improving intermediate wheatgrass varieties for yield and disease resistance. 

Across borders for a cause 

Alexa Nicole Peterson’s leap into international academia was almost serendipitous. While exploring PhD opportunities, she searched for positions related to perennial crops and stumbled upon a program at Aarhus University. “I hadn’t planned on moving overseas,” she admits. “But the research aligned perfectly with my interests, and I couldn’t pass it up.”  

Seven months into her PhD, Alexa Nicole Peterson is immersed in understanding how perennial crops—plants that grow for multiple seasons without replanting—can transform sustainable agriculture. Her work focuses on optimising these crops for Danish conditions, examining fertilisation rates, and exploring farming practices that can unlock their environmental benefits.  

The appeal of perennials 

Perennial crops offer several advantages over traditional annual crops like wheat and canola. Their long growing seasons reduce the need for frequent tillage and planting, leading to less soil erosion, better carbon sequestration, and overall reduced environmental impact. 

But the research is not without its challenges. “We’re still in the early stages of understanding how these systems function,” Alexa Nicole Peterson explains. “It’s exciting to think about how this knowledge could transition from being just an idea to something that’s implemented on farms in the future.”  

One of the standout findings from her first field season is the extensive root depth of these crops, which not only improves soil health but also offers promising solutions for compressed soils and carbon storage. 

A personal connection 

Alexa Nicole Peterson’s passion for sustainable agriculture is deeply rooted in her upbringing. Growing up on her family’s grain farm in Saskatchewan, she witnessed firsthand the challenges and rewards of farming life. Her grandfather has even started experimenting with planting perennials, inspired by her research.  

“It’s like having an on-farm experiment back home,” she says with a smile. “It’s rewarding to see my family embrace the potential of these systems.” 

Her background also gives her a unique perspective when communicating with farmers. “Understanding their concerns and decisions is crucial. It helps me frame my research in ways that are practical and relatable to them.” 

Balancing curiosity with impact 

When asked what motivates her, Alexa Nicole Peterson highlights her desire to bridge sustainability with practicality. “I want to create systems that benefit both society and farmers. Even if the difference is small, every step toward sustainability matters.”  

Her curiosity also drives her forward. “I’ve always been the kind of person who reads the instruction manual first,” she jokes. “It’s about understanding how things work and then figuring out how to improve them.” 

While Alexa Nicole Peterson’s career goals are still taking shape, she envisions herself contributing to the green transition and circular bioeconomy. She’s particularly interested in exploring how on-farm practices can combine economic viability with environmental sustainability.  

Her research area, though still novel, holds immense potential. “The next decade will likely bring significant advancements,” she predicts. “I hope we can move from theory to practical implementation, making perennial crops a valuable addition to farmers’ toolkits.” 

Life beyond the lab 

Despite the demanding nature of academia, Alexa Nicole Peterson maintains a healthy work-life balance. An advocate for strong organisational skills, she plans her weeks meticulously but also finds time to unwind. She plays volleyball, exercises regularly, and has recently taken up painting—a hobby inspired by her artist mother.  

“Painting is a way to tap into my creative side,” she shares. “It’s a reminder to stay grounded and enjoy the simple pleasures in life.” 

The roots of change 

As Alexa Nicole Peterson continues her research, she embodies the hope and determination needed to tackle agriculture’s biggest challenges. Through her work, she not only seeks to enhance the sustainability of farming systems but also inspires others to see the profound impact of small, meaningful changes.  

With her passion and persistence, Alexa Nicole Peterson is proving that the future of agriculture lies in the hands of those willing to dig deep—both in the soil and in their curiosity.
