Tsegaye Lemmi was born in Ethiopia. He earned his bachelor’s degree in Textile Engineering from Bahir Dar University, Ethiopian Institute of Textile and Fashion Technology, Ethiopia, in 2015. Following the successful completion of his BSc, he began working as an Assistant Lecturer at the same university. In 2016, he was awarded a full scholarship from the Government of Poland under the "Ignacy Lukasiewicz scholarship program." This opportunity enabled him to pursue a master’s degree at the Faculty of Material Technologies and Textile Design, Lodz University of Technology. He obtained his master’s degree in Textile Engineering in 2019.
Determined to further his academic pursuits, Tsegaye continued his journey by undertaking a Ph.D. in Materials Engineering at the Interdisciplinary Doctoral School of Lodz University of Technology, completing his doctoral studies in 2023. During his doctoral studies, he collaborated with industry leaders in the field of Mechanical Rubber Goods (MRGs), focusing on the physio-mechanical property analysis of Textile reinforced conveyor belts. He also received various scholarships and awards during his studies.
Tsegaye’s academic journey is complemented by practical experiences gained through internships and collaborations with esteemed institutions, including Saygin Dima Textile Share Company in Ethiopia, Bahir Dar Textile Share Company in Ethiopia, the Łukasiewicz Research Network – Lodz Institute of Technology in Poland, University of Boras in Sweden, Sempertrans bełchatów Ltd. in Poland, Kordarna a.s company in the Czech Republic, and many more.
Since October 2022, he has been actively contributing to the academic community as a Project Administrator at the Lodz University of Technology, working on the EU-funded project "Sustainable Industrial Design of Textile Structures for Composites." Additionally, since October 2023, he has been serving as a lecturer and researcher at the Institute of Architecture of Textiles, Lodz University of Technology.
Tsegaye’s research interests encompass the design and property analyses of textile reinforced composites, textile reinforced mechanical rubber goods, the design of woven fabric structures, and the mechanical property analyses of fibers, yarns, and fabrics for technical purposes. He has showcased his scholarly abilities as the author and co-author of various scientific papers, including conference proceedings.
