From pioneering supercritical impregnation methods to exploring bio-based chemicals, Obiora Muojama’s research career reflects an unwavering commitment to sustainability and innovation. Currently a PhD student at the University of Alabama, USA, Muojama’s body of work spans renewable materials, biomass valorization, and sustainable chemical processes.

Muojama’s academic journey began at the University of Benin, Nigeria, where he graduated with first-class honours in Chemical Engineering. “My early exposure to biomass research sparked my curiosity about turning waste into value,” he recalls. That curiosity has blossomed into a career defined by green chemistry and Engineering.

Among his notable publications is a comprehensive review on oxalic acid biosynthesis from bio-derived substrates, exploring sustainable production methods that could replace fossil-derived processes. “Oxalic acid has huge industrial potential, but current production methods aren’t environmentally friendly,” Muojama explains. His review maps out alternative pathways using renewable feedstocks.

In another project, Muojama applied machine learning and global sensitivity analysis to optimize citric acid production from yam peels, a common agricultural waste in Nigeria. This work not only advanced biotechnological conversion but also demonstrated the power of data-driven modelling in chemical engineering.

Beyond biochemicals, Muojama has investigated the use of natural oils, such as Cucumeropsis mannii, as biodiesel feedstocks and heavy metal sorbents. His research into heavy metal sorption using thiolate oil provided low-cost solutions for wastewater treatment, aligning with his broader goal of accessible, sustainable technologies.

A distinguishing feature of Muojama’s work is the integration of advanced techniques, from Design of Experiments (DOE) to spectroscopic analysis and material characterization tools like FTIR, XRD and SEM. These skills have allowed him to bridge theoretical models with practical applications.

His impact extends beyond research papers. As a recipient of the prestigious MTN Foundation Technology Scholarship for four consecutive years and multiple international scholarships, Muojama has gained recognition for academic excellence. Notably, he served as a judge for the 2024 USA STEM Showcase and significantly supported in the construction of a new chemical research laboratory in Nigeria, highlighting his commitment to community development.

Muojama’s leadership is equally evident in his role as President of the National Association of Akwaeze Students (NAAS) and his service with the Nigerian Young Researchers Academy (NYRA). “Science should not happen in isolation,” he says. “Mentoring and community service ensure research benefits everyone.”

Active participation in conferences; including the ACS (American Chemical Society) Green Chemistry & Engineering Conference and AIChE (American Institute of Chemical Engineers) Annual Meeting, has amplified Muojama’s influence, connecting him with researchers worldwide. These engagements have helped translate complex findings into accessible solutions.

In the profession of teaching, Muojama has served as a Graduate Teaching Assistant, supporting courses like Reactor Design and Transport Phenomena at the University of Alabama. “Teaching keeps me grounded,” he reflects. “It reminds me why this work matters.”

Currently, Muojama’s doctoral research focuses on Engineering Cellulosic Substrates through Supercritical Impregnation Technology’s, a topic central to advancing natural materials for industrial applications. His work aligns with global sustainability goals and the push for renewable alternatives.

Looking forward, Muojama envisions a research career where innovation directly addresses pressing environmental challenges. “My goal is to develop materials and processes that industries can adopt without sacrificing performance,” he says.
