In the quiet of a greenhouse at Trent University, a PhD candidate is proving that breakthrough science often begins with a single, focused question. Tyra Lewis, a Materials Science doctoral candidate, has spent seven years investigating how electrical energy drives chemical reactions—a field known as electrochemistry. Her work has earned her three major awards in a single year, including the Electrochemical Society (ECS) Canada Section Student Award, a first for any Trent student. But beyond the accolades lies a story that matters to anyone following innovation in agriculture Canada, environmental science, or the direction of graduate research at Canadian universities.
This article examines what Lewis’s achievements reveal about Trent University research excellence, how Canada electrochemistry research is addressing real-world agricultural problems, and what prospective graduate students and researchers can learn from her path.
Why Electrochemistry Matters for Canada’s Environmental and Agricultural Future
Electrochemistry sits at the intersection of chemistry, energy, and environmental science. It studies how electrical energy and chemical reactions interact, and its applications extend far beyond batteries and industrial processes. Researchers in this field are developing greener ways to synthesize compounds, recycle materials, and detect substances in the environment.
Lewis’s early research explored electrochemistry as a cleaner approach to synthesizing and recycling organic compounds derived from environmental pollutants. This kind of work addresses a pressing global need: finding alternatives to traditional chemical processes that generate waste and rely on harsh reagents. In Canada, where environmental monitoring and sustainable resource management are national priorities, this research area is gaining significant traction.
For students considering graduate studies, the lesson is clear—fields like electrochemistry offer the chance to work on problems with tangible environmental and economic consequences. The Trent University News-Canada coverage of Lewis’s work highlights a broader trend: universities are investing in interdisciplinary programs that connect fundamental chemistry to applied challenges in agriculture, forensics, and environmental health.
Tyra Lewis Awards: Recognizing Research Excellence at Trent University
Lewis’s list of recognitions is substantial for a doctoral candidate. In addition to being the first Trent student to receive the ECS Canada Section Student Award, she earned the Analytical Chemistry Division of the Chemical Institute of Canada (CIC) Graduate Student Award and the International Conference for Analytical Sciences and Spectroscopy (ICASS) Burgener Research Graduate Student Travel Award.
These awards reflect more than individual talent. They demonstrate the quality of mentorship and research infrastructure available at Trent. Dr. Sanela Martic, associate professor in Forensic Science and Lewis’s supervisor, noted that her contributions have extended well beyond his lab, earning national and international recognition.
What makes this trajectory notable is its interdisciplinary breadth. Lewis joined the Martic Lab in 2019 and completed both her undergraduate degree in Forensic Science and her master’s in Environmental and Life Sciences at Trent while conducting research. Along the way, she contributed to projects spanning forensic science, environmental chemistry, biochemistry, and aerosol science.
For prospective graduate students, this illustrates an important point: modern research careers rarely follow a single disciplinary track. Programs that allow students to move across subfields—and supervisors who encourage that movement—can produce researchers capable of tackling complex, real-world problems.

From Pollutants to Soil Health: Applying Electrochemistry in Agriculture
Lewis’s current research direction shows how fundamental expertise can pivot toward new applications. She is now focused on a problem that directly affects Canadian farmers: measuring soil health quickly and affordably.
Sugars in soil serve as a natural food source for microorganisms. When microbial activity increases, soil health improves—supporting nutrient cycling, plant growth, and overall productivity. But traditional methods for detecting sugars in soil rely on large analytical instruments that are expensive and time-consuming to operate. This creates a barrier for on-site testing, especially for farmers who need fast answers in the field.
Lewis is developing two solutions:
- A smartphone-compatible electrochemical sensor that can deliver rapid results using a device most people already carry.
- A colour-change test kit that provides a simple visual readout, making testing accessible even without specialized training.
Both approaches aim to make soil health assessment faster and more affordable, giving farmers the information they need to make informed decisions about crop management. This is a concrete example of how Canada electrochemistry research is feeding into innovation in agriculture Canada—a sector under increasing pressure to adopt sustainable, precision-driven practices.
The agricultural implications are significant. On-site soil testing could help farmers optimize fertilizer use, reduce waste, and improve yields. In a country where agriculture contributes substantially to the economy and faces challenges from climate variability, tools that support faster decision-making carry real value. Researchers and entrepreneurs interested in agri-tech innovation should watch this space closely, as sensor-based soil diagnostics are an area of active development worldwide.

What Lewis’s Path Teaches Aspiring Researchers
There are practical lessons in Lewis’s story for anyone considering a research career in Canada:
Start Early and Build Across Disciplines
Lewis began working in the Martic Lab as an undergraduate and continued through her master’s and doctoral studies. That continuity allowed her to develop deep technical skills while exploring adjacent fields. Students who get involved in research early—before graduate school—often find themselves better positioned for awards, publications, and funding opportunities.
Choose Problems with Real-World Relevance
Her shift from pollutant recycling to soil health testing reflects a deliberate choice to work on problems with global impact. Funders and award committees increasingly look for research that addresses practical challenges. Framing your work in terms of its applications—whether in agriculture, environmental monitoring, or public health—can strengthen both grant applications and award nominations.
Seek Mentorship and Institutional Support
Lewis’s success is inseparable from the environment at Trent. Her supervisor’s endorsement and the university’s interdisciplinary graduate programs gave her room to grow. When evaluating graduate programs, look beyond rankings: examine the specific labs, funding structures, and award track records of the departments you’re considering. Prospective students can review Trent’s graduate program offerings to compare options in environmental and materials sciences.
Award Applications Are Worth the Effort
Three national and international awards in one year did not happen by accident. They required applications, nominations, and a supervisor willing to advocate for her work. Graduate students sometimes overlook award opportunities, assuming they are too competitive. Lewis’s example suggests otherwise—consistent, high-quality research paired with diligent applications can yield significant recognition. Students preparing award submissions should start early, gather strong letters of support, and clearly articulate the impact of their research. If you are navigating the awards process, reach out to university research communications teams for guidance on preparing competitive submissions.
The Broader Context: Canadian Universities and Applied Research
Lewis’s story fits within a larger narrative about the role of mid-sized Canadian universities in applied research. While large research-intensive institutions often dominate headlines, schools like Trent demonstrate that focused programs with strong mentorship can produce nationally recognized scientists.
The connection between Trent University research excellence and innovation in agriculture Canada is particularly relevant now. Canadian agriculture is under pressure to adopt technology that improves sustainability—precision agriculture, sensor networks, and rapid diagnostics are all growth areas. University research labs are often the incubators for these technologies before they reach commercialization.
For students, this means graduate training in fields like electrochemistry, analytical chemistry, and materials science can lead directly into careers in agri-tech, environmental consulting, government research, and industry R&D. The skills Lewis describes—core technical competencies paired with adaptability across projects—are exactly what employers in these sectors seek.
Looking Ahead: Soil Sensors and the Future of Farming
The smartphone-compatible sensor and colour-change test kit Lewis is developing could reshape how soil health is monitored. If successful, farmers would no longer need to send samples to distant labs and wait days for results. Instead, they could test in the field, adjust their practices immediately, and track soil health over time with minimal cost.
This vision aligns with broader trends in agricultural technology, where low-cost sensors and mobile integration are making data-driven farming accessible to smaller operations—not just large industrial farms. As Lewis noted, the potential global impact motivates her to keep pushing the work forward.
For Canadian readers—whether farmers, students, or researchers—the takeaway is that meaningful innovation often comes from unexpected places. A forensic science lab at a university in Peterborough, Ontario, is contributing tools that could influence agricultural practice here and abroad.
