Meet student researchers solving real-world challenges

Developing sustainable solar energy solutions, deploying fungi to support soils affected by wildfire, making space education more accessible and using machine learning for semiconductor material discovery — these are just some of the ways students at Arizona State University are addressing real-world challenges through hands-on research.

At the Ira A. Fulton Schools of Engineering at ASU, undergraduate and graduate students have several opportunities to conduct use-inspired research in which they can apply their classroom knowledge and build new skills. Through individual projects mentored by Fulton Schools faculty members, students deliver innovation that matters in the research themes of data science, education, energy, health, security, semiconductor manufacturing and sustainability.

The Fulton Undergraduate Research Initiative, or FURI, and the Master’s Opportunity for Research in Engineering, or MORE, programs give participants valuable experiences in which they conceptualize ideas, develop plans and investigate their research questions over a semester.

Students participating in the Grand Challenges Scholars Program, or GCSP, can apply for additional funding to conduct research through the GCSP research stipend program. Conducting research is part of a GCSP student’s rigorous competency requirements designed to prepare them to solve complex global societal challenges.

These three programs enhance students’ ability to innovate, think independently and solve problems in their communities. They also benefit from the technical and soft skills they gain, which prepare them for their careers and the pursuit of advanced degrees.

Each semester, students who participate in FURI, MORE and the GCSP research stipend program are invited to present their findings at a poster session. The Fulton Forge Student Research Expo is the culmination of the students’ hard work to forge meaningful research paths and connections to make an impact.

Learn about four students who are participating in the spring 2024 Fulton Forge Student Research Expo. Meet them and more than 100 other student investigators at the event, which is open to the public, on Friday, April 19, from 1 to 3 p.m. at the Student Pavilion on the ASU Tempe campus.

Clara Chaves Azevedo

Civil engineering major Clara Chaves Azevedo is conducting research to reduce the toxicity of promising perovskite materials to implement solar energy generation on windows with faculty mentor Nick Rolston, an assistant professor of electrical engineering.

Henry Nakaana

Civil engineering first-year student Henry Nakaana’s FURI project with Emmanuel Salifu, an assistant professor of civil and environmental engineering, involves engineering fungi that could help support areas affected by increasingly frequent wildfires and heavy rains that make soil vulnerable to erosion and landslides. 

Q: What made you want to get involved in FURI and the project you’re working on?

Nakaana: I joined FURI to gain experience in research, obtain knowledge that can help me improve my career and technical engineering skills, and also contribute valuable insights to the scientific community. My project explores the engineered growth of fungi as a novel method to improve stability and erosion resistance on post-wildfire soils. I chose this project because it aligns with my passion for using nature-based solutions to solve engineering problems.

Q: How will your engineering research project impact the world?

Nakaana: Today the occurrence of wildfires is expected to increase greatly in the northern parts of the U.S. and Canada, which will leave soil exposed to erosion and landslides. My research project offers an effective, budget-friendly and fast way to protect post-wildfire soils compared to other available solutions. My project also shows the additional advantages of using fungi on soil such as carbon sequestration, which helps reduce global climate change.

Q: What has been your most memorable experience as a student researcher?

Nakaana: One of my most memorable moments was when I realized the initial fungi growth on the soil. It was so amazing how fungi can grow in as little as two days to cover the whole soil surface. It made me feel more like an explorer uncovering secrets in a scientific space whose potential has not been discovered.

Q: How do you see this experience helping with your career or advanced degree goals?

Nakaana: The unique combination of engineering and ecological considerations in this project aligns perfectly with my career aspirations to use sustainable technology. Furthermore, this experience not only adds depth to my academic qualifications but also establishes a valuable network within the scientific community on a research topic that is just growing globally.

Collaborating with experts in the field through my mentor has broadened my perspective and allowed me to contribute to cutting-edge research. These aspects, combined with the tangible outcomes of the project, will increase my credibility and open doors to opportunities for further education and advancement in my engineering career.

Ritwik Sharma

Aerospace engineering sophomore Ritwik Sharma is working on a cross-disciplinary project with Daniel C. Jacobs, an assistant professor in the ASU School of Earth and Space Exploration, to share his passion for space. His work, funded by the GCSP research stipend opportunity, involves developing a wayfinding method for the Completely Hackable Amateur Radio Telescope, known as CHART, an inexpensive and simple way to use radio waves to see features in outer space not visible to the human eye. He aims to make the system more accessible for individuals and K–12 classroom instruction.

Q: How will your research project impact the world?

Sharma: The guidance system I am designing for CHART will give K–12 students a way to understand how astronomers observe different parts of the universe with radio telescopes. This will improve their understanding of astronomy as a field by teaching them how astronomers locate objects in the sky, and why they have to rely on coordinates as opposed to general directions.

Since the Earth is constantly revolving around the sun, our frame of reference is constantly changing, which makes coordinate systems like right ascension and declination and galactic an important part of the subject because they make tracking objects like galaxies and nebulae easier.

Q: How do you see this experience helping with your career or advanced degree goals?

Sharma: I plan to pursue a doctorate after I graduate from ASU, and I see this experience helping me by showing my future supervisors that I am capable of pursuing a project on my own, under the instruction of a mentor. This arrangement is common in graduate school where students work under the direction of their advisor on projects like their theses, dissertations or other items necessary to complete their doctoral or master’s degree. By showing my ability to work efficiently on a project like this, I can also show my future thesis advisor that I will be perfectly capable of completing something like a doctoral thesis, which will give me an advantage over other applicants.
