Hhayuma Emily Sixberth received his B.Ed. in Science (Chemistry) from the University of Dar es Salaam in 2020, after completing his secondary education at Kisarika High School with a focus on physics, chemistry, and biology. From August 2020 to July 2023, he worked as a high school chemistry teacher at St. Dominic Savio Kigonzile High School, where he taught chemistry and supervised laboratory practicals. His teaching experience strengthened his expertise across analytical and physical chemistry, chemical thermodynamics, inorganic chemistry, electrochemistry, and chemical kinetics. In August 2024, he joined the NanoElectroChemistry Laboratory (NECL) at Daegu University, and since September 2024, he has been pursuing his M.S. degree in Chemistry at Daegu University Graduate School. His current research interests focus on electrochemical energy conversion and storage, with particular emphasis on catalyst development and structure–property relationships for sustainable reactions such as water splitting and nitrogen reduction. By combining his background in education with advanced research in chemistry and materials science, he aims to contribute to the development of efficient, low-cost catalytic systems that address global energy and environmental challenges.
