Biography

Biography

Dr. Amos S. Kiyumbi is a Physics lecturer and Nanophotonics Physicist at Dar es Salaam University College of Education (DUCE), a constituent college of the University of Dar es Salaam in Tanzania. He specializes in plasmonic nanomaterials and metamaterials for optical biosensors, integrating experimental and theoretical approaches. Kiyumbi holds an MSc from Ulm University in Germany, where he focused on single-crystal gold nanostructures, and a PhD from Stellenbosch University in South Africa, (graduated March 2026), on plasmonic nanostructured sensors for malaria biosensing. His work includes developing ultra-sensitive biosensors for in vitro malaria detection, with significant contributions such as conference presentations and peer-reviewed article publication.

 

In his teaching role, Dr. Kiyumbi delivers high-quality undergraduate courses in Nano and Materials Science, Photonics, Quantum, and Optics, emphasizing practical applications for resource-limited healthcare diagnostics. He co-founded the Tanzania Photonics, Quantum, and Laser Technology Initiative Consortium, with a launch forthcoming, and advocates for a National Center of Excellence in Photonics and Laser Technology to build a skilled nanotech workforce through modern optics labs and industry partnerships. As an active member of Optica (formerly OSA) and SPIE, he engages with leading international optics and photonics societies. Additionally, Dr. Kiyumbi leads a community-based organization (Reg. No. MDC/CBO/4196) in Magu, Mwanza, Tanzania, dedicated to supporting underprivileged young science students and promoting inclusive STEM education.
