IGBARIAM, Anambra State — Chukwuemeka Odumegwu Ojukwu University (COOU) is celebrating a standout research milestone as two faculty members—Dr. Johnbosco C. Egbueri (Department of Geology, Faculty of Physical Sciences; Associate Director, Research Management Office) and Engr. Dr. Titus Chinedu Egbosiuba (Department of Chemical Engineering, Faculty of Engineering)—have been listed in the 2025 World’s Top 2% Scientists ranking compiled by Stanford University and Elsevier.
The globally benchmarked assessment, drawn from comprehensive Scopus analytics, evaluates scholars on a rigorous blend of indicators including scholarly impact, citation frequency, and sustained research productivity across international networks. For COOU, the recognition lands as both validation and signal: the University’s research profile is rising—and fast.
In Dr. Egbueri’s case, the honour extends a remarkable run of five consecutive years (2021–2025) in the Top 2% lists, reinforcing a reputation for consistent, high-impact scholarship. Earlier in April, ScholarGPS named him a 2024 Highly Ranked Scholar (Top 0.05%), with distinctions spanning Overall (All Fields), Physical Sciences and Mathematics, and focused domains such as Earth and Planetary Sciences, Water Resources, Groundwater, Health Risk Assessment, Heavy Metals, Drinking Water, and Pollution studies—evidence of the interdisciplinary reach and real-world relevance of his work.
Engr. Dr. Egbosiuba earned his place in the 2025 cycle, joining an elite community of researchers worldwide. His ranking cuts across Engineering, Environmental Sciences, Biotechnology, and Biomedical fields, propelled by influential contributions in Nanotechnology for water treatment, materials science, catalysis, fuels production, agricultural productivity, and cement technology in the built environment. The scope and utility of his research underline how COOU’s scholarship is tackling urgent global challenges with solutions that benefit society and the environment.
What makes this dual recognition especially resonant is that both honourees are COOU alumni—a powerful narrative of talent nurtured at home and scaled to global impact. Their journeys from the University’s lecture halls to international research leaderboards affirm COOU’s capacity to develop scholars whose work travels well beyond campus.
The achievements also map cleanly to COOU’s strategic 3Vs framework—VALUES (research excellence and academic distinction), VISIBILITY (global recognition of institutional expertise), and VIABILITY (reputation capital that attracts collaborations and opportunities). As the University deepens its research culture, these wins add momentum to COOU’s expanding global profile.
In messages shared with COOUNewS, Engr. Dr. Egbosiuba expressed gratitude to University leadership: “I am truly grateful to the Vice Chancellor, Prof. Kate Azuka Omenugha, for her exceptional leadership… and for her commitment to the 3Vs mandate, which has fostered an environment of intellectual growth and strong character development, thereby making COOU excel in research and ethics, positioning the university for global recognition, and inspiring ongoing excellence.”
Dr. Egbueri highlighted both humility and institutional vision: “Divine providence has been instrumental throughout this journey… My sincere appreciation goes to our Vice Chancellor for her encouragement and visionary leadership, which continuously inspires our academic community toward excellence that would reposition COOU for enhanced global visibility and scholarly impact.” He added: “I have long held the conviction that COOU harbours talents capable of bringing immense pride to our alma mater… My hope centers on seeing more distinguished scholars emerge from COOU in coming years… I am confident that more COOU researchers will earn these prestigious international rankings.”
For COOU, the take-away is clear: impactful research is now a defining feature of the institution’s identity. With Dr. Egbueri and Engr. Dr. Egbosiuba serving as catalysts and exemplars, the University is strengthening its standing in the international academic community and offering a blueprint for future generations of scholars—proof that graduates can shape global knowledge while advancing solutions that matter at home.
