Alemayehu Dubale (PhD)

Dr. Alemayehu Dubale is a Senior researcher and Director of the Nanotechnology Directorate at the Bio & Emerging Technology Institute in Addis Ababa, Ethiopia. He obtained his Ph.D. in Applied Chemistry and Nanotechnology from National Taiwan University of Science and Technology (NTUST), Taipei, Taiwan in a year 2018. Before his PhD study, he was serving as a lecturer and head of Chemistry department at Aksum University. His research interests include nanomaterials for sensors, energy storage and energy conversion, Agro-industry waste utilization, green chemicals, waste treatment. He is currently working on synthesis and characterization of nano-structured metal oxides for waste treatment and various value-added products. Generally, green synthesis technique that led to innovative and commercially viable materials including composite materials, whose relative applications fall in catalysis, water treatment, and replacement of toxic and hazardous chemicals by greener alternatives are also areas of focus.
