In an era where the global community is confronting critical environmental and energy challenges, few scientists stand at the intersection of Materials Chemistry, nuclear waste remediation, and sustainable innovation. One such rising figure is Oketola Oluwaseun, a Ph.D. candidate in Chemistry at Jackson State University, Mississippi, whose work is redefining how we manage radioactive and industrial contaminants.

Hailing from Nigeria, Oluwaseun’s journey began with a Bachelor’s degree in Chemistry from Olabisi Onabanjo University, where he developed a strong foundation in Analytical and Environmental Chemistry. After gaining industrial experience in quality control, research and development, and environmental safety roles, he transitioned to graduate studies in the United States, where his academic and research trajectory accelerated.
Oluwaseun is developing advanced porous materials known as chalcogels, which are capable of capturing and immobilizing toxic radionuclides like technetium-99, a hazardous byproduct of nuclear weapons production. These amorphous, sponge-like materials are tailored to meet the demanding requirements of U.S. nuclear waste remediation efforts across contaminated sites in the United States. What sets Oluwaseun apart is not just the novelty of his materials but the national relevance of his work.

“My goal is to design materials that not only bind radioactive contaminants efficiently but also remain stable in real-world nuclear waste environments,” he says.

His research, conducted in collaboration with the Savannah River National Laboratory (SRNL) directly supports national cleanup efforts at high-stakes locations such as the Hanford Waste Treatment Plant in Washington State.

Through cutting-edge analytical techniques, including X-ray Absorption Spectroscopy (XAS) methods such as X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS), as well as Pair Distribution Function (PDF) analysis, Oluwaseun investigates how radioactive ions interact with the structural frameworks of his chalcogel-based materials at the atomic level. XANES provides information about the oxidation state and electronic structure of the absorbed elements, while EXAFS reveals their local coordination environment and bonding distances. These advanced characterizations allow for the precise tuning of sorbent materials to improve their selectivity and stability in the complex chemical environments of nuclear waste streams.

While his work on nuclear waste remediation is groundbreaking, Oluwaseun is also exploring how these materials can be applied to industrial wastewater treatment and energy storage systems, advancing research in environmental protection and clean energy. His chalcogel-based materials are being investigated as electrochemical cathodes for lithium-ion batteries and as sorbents for removing heavy metals like chromium and lead from contaminated water aligning his work with broader U.S. goals in environmental protection and clean energy technology.

As a published author in high-impact peer-reviewed scientific journals, Oluwaseun has demonstrated exceptional ability and thought leadership in his field. His publications not only disseminate original research findings but also serve as compelling evidence of his ability to conduct work of national and international significance, contributing meaningfully to the advancement of his field. These contributions have further strengthened his reputation as a rising expert in Nuclear Chemistry and Materials Science. His commitment to mentorship and diversity in STEM also underscores his role as a leader beyond the laboratory.

Oluwaseun’s research is more than academic—it addresses core U.S. national interests in public health, environmental remediation, and energy innovation. His scientific contributions align with long-term government priorities and reflect the kind of extraordinary ability that America seeks in its future citizens. As policymakers and agencies search for transformative thinkers to help solve today’s toughest challenges, Oketola Oluwaseun’s work stands as a model of global talent driving national progress.
