Amid the global call for sustainable and more economical energy solutions, a Nigerian engineer, Nkechi Nwaogaraku, is standing out for her groundbreaking work in sustainability research and innovation.

Nwaogaraku is a committed researcher and process model simulation expert currently pursuing her Master’s in the Engineering Department at Iowa State University in the United States. With a solid academic background in Applied Physics from the University of Lagos and a Master of Science in Renewable Energy Technologies from KNUST in Ghana, Miriam has steadily built a reputation for excellence in renewable energy systems and biorefinery process modelling. Her research focuses on transforming biomass into valuable chemicals and fuels through sustainability assessments and high-performing simulations.

Among her most notable achievements is her recent presentation at the 2024 AIChE Conference, where she showcased her work titled “Techno-economic analysis and life cycle analysis of itaconic acid under a biorefinery approach.” The project demonstrated her ability to use powerful modelling simulation tools such as BioSTEAM, GREET and OpenLCA to evaluate the technical and environmental impact of bio-based chemical products.

At Iowa State, she works as a research assistant developing and evaluating integrated biorefinery systems. Her contributions include designing process models, conducting techno-economic evaluations, and performing environmental assessments, all with the aim of promoting more sustainable industrial practices. Her collaborative spirit is reflected in her regular presentations at research meetings and symposiums, including the Virginia and William Binger Graduate Research Symposium in 2024.

Miriam’s journey is supported by several prestigious scholarships which including the Engineering Education Project award from KNUST and the Seward, Ratcliffe and Galloway Foundation scholarship from Iowa State University. She is also a recipient of the Ohanaeze Ndigbo Southwest Scholarship Award during her undergraduate program.

Outside of academics, she has gained practical experience in the energy industry during her internship at Rubitec Nigeria Limited, where she worked on solar installations and energy systems analysis using tools like PVsyst and SAM software. Her practical skills extend to troubleshooting machinery, supporting workshops, and mentoring peers in operational best practices.

Miriam is also an active member of the American Society of Mechanical Engineers and the National Society of Black Engineers, and has participated in various scientific and technical conferences. Her career path reflects a rare combination of technical brilliance, commitment to environmental sustainability, and a drive to create real, practical solutions
