Eng. Geo. Ngabia Nyahili is an Assistant Lecturer in the Department of Mining and Mineral Processing Engineering at the University of Dar es Salaam. I hold a Master of Engineering in Geological Resources and Geological Engineering from Hohai University, China, and a Bachelor of Science in Engineering Geology from University of Dar es Salaam.

With both academic and field-based expertise, I have specialized in rock mechanics and engineering, stability analysis of rock slopes, underground excavations, and geohazard assessment and mitigation. My professional background includes hands-on involvement in mineral exploration projects across Tanzania, covering geological mapping, trenching, geochemical sampling, drilling supervision, and mineral resource evaluation for commodities such as gold, limestone, feldspar, quartz, and industrial minerals.

At UDSM, I teach undergraduate courses in Applied Rock Mechanics, Dam Engineering, and Rock Excavation and Support. I am also actively engaged in curriculum development and supervision of student research projects. Beyond teaching, I collaborate with multidisciplinary teams in the mining sector, contributing technical expertise in geotechnical investigations, geological data analysis, 3D modeling, and geospatial and geochemical datasets integration for exploration and mining decision-making.

My research interest focuses on numerical analysis of rock mass stability, mining geomechanics, and sustainable mineral resource development. I have participated in national and international projects and maintain strong academic networks, particularly with institutions in China, where I am pursuing a Ph.D in Geological Engineering under a CSC  scholarship.

My work reflects a commitment to advancing safe, sustainable, and efficient mining practices, while fostering the next generation of engineers and geoscientists through teaching, mentorship, and applied research.
