Fidelis Onwuagba, a master’s student in geology, was drawn to K-State’s academic excellence, renowned faculty, and especially how well the geology department fit with his own research interests.
“My interest in geology stems from my early exposure to the dynamic processes that modify the Earth,” he said. “I have always been fascinated by the thought that under the surface of our world lies a complex world of rocks, minerals, and geological formations, each telling a unique story of our planet’s history.”
According to Onwuagba, understanding geology is critical to tackling modern environmental concerns. Therefore, it has become essential to his academic and professional career.
Also, the multidisciplinary nature of geology combining elements of chemistry, physics, and biology – appeals to his approach to scientific research.
“I chose geology as my course of study because I wanted to investigate the Earth’s subsurface, comprehend its geological history, and contribute to sustainable resource management,” he said. “Geology is not just a career path for me. It’s a passion that allows me to delve into the very foundations of our planet and contribute to the responsible stewardship of its resources.”
He has conducted research into uranium as a natural contaminant in groundwater, which he said has significance as uranium and other trace metals above certain limits in groundwater pose significant health risks.
For instance, Onwuagba has investigated levels of uranium in groundwaters located in the Cherokee Basin in southeast Kansas. He said this is critical for understanding potential human exposure through drinking water.
“The research looks at the geological processes that lead to the occurrence of uranium and other toxic trace metals in groundwater. Understanding these processes gives insights into natural contamination pathways and helps forecast and manage similar occurrences in other geological environments,” he said.
This research helps improve water management for many communities as it identifies locations that are prone to trace metal contamination so that policies to protect the safety and sustainability of water sources can be properly implemented.
Onwuagba has also taken the opportunity to communicate the value and impact of his research audiences outside of his field of study. This year, he participated in the Switch International Energy Case Competition and K-State’s Research and the State Poster Forum, and his participation paid off.
Onwuagba and his international team, EnerGreen, were selected as the winners of the Switch International Energy Case Competition. He was also selected with 10 other participants in the Research and the State poster forum to present his research poster to Kansas legislators at the State Capitol in the annual Capitol Graduate Research Summit in March 2024.
Fidelis Onwuagba presents his research at the 2023 Research and the State poster forum at Kansas State.
“These competitions honed my research, critical thinking, communication, and problem-solving abilities,” said Onwuagba.
This is particularly true for the Research and the State Poster Forum. Onwuagba said the experience in participating in the forum enhanced his ability to communicate technical information to a diverse audience – a skill that’s essential for him in both academic and public engagements.
“Research competitions provide a unique platform to immerse myself in intellectually stimulating challenges,” Onwuagba said. “The opportunity to delve into complex issues, devise innovative solutions, and present them convincingly taps into my innate curiosity and passion for problem-solving.”
After completing his master’s program, Onwuagba hopes to make significant contributions to the clean and renewable energy field.
“I am excited about pursuing a Ph.D. in this field because it aligns with my passion for sustainable solutions and addressing the world’s energy challenges,” he said.
Onwuagba said his ambition is to gain advanced knowledge while actively contributing to the on-going clean energy discourse so as to make a positive impact on our global transition to more sustainable practices.
“Kansas State University’s academic reputation, faculty expertise, and welcoming and collaborative community made it the ideal choice for pursuing my graduate studies, as I believe that diverse perspectives contribute significantly to the richness of academic discourse,” he said. “The experience has been really fulfilling, and I am grateful for the opportunities for learning and research that the university has provided me.”
