ZALFA MAULIDA IHSANI

I am a Doctoral student in Civil and Environmental Engineering at Ehime University. I am deeply passionate about exploring sustainable materials for infrastructure development. I have acquired expertise in both theoretical principles and practical applications, collaborating with interdisciplinary teams. I am a well-adapted person, having conducted research in a foreign country. I am enthusiastic about the prospect of contributing my knowledge and skills to address the evolving challenges in soil improvement and sustainable infrastructure within your laboratory.
